e46 manual transmission noiseTo start viewing messages,Any input is appreciated. Thanks, Kevin.What sounds loud to me might not be noticeable to you, and vice versa.But its wild guessing.Its sounds like it is something that occurs during a load transfer.The noise I described is definitely coming from the front of the car.Not how I'd describe the sound, but that can get pretty subjective. Good luck.I hear a loud banging noise at 3.5k rpm comming from under the center console.I had found a thread a while back that had a solution but I didn't bookmark it. Did you ever come up with a solution. Hope all is well.Start the car and replicate the sound, verify where it's coming from. Then get under the car and have your trusted partner (not someone who's named in your will) start the car and try to replicate the sound. You should then be able to hear and see (from movement) just where it's coming from. If the trans has been replaced on the advice of your mechanic and at great expense, and it didn't solve the problem, time for another mechanic. They should never suggest major expense repairs that don't work. Still they are human. It's possible that the clutch release bearing is binding (not sliding back and forth as it should) but you should feel a pronounced jerk when shifting, not just a noise. And since the trans was replaced, all should be good in there.As the noise occurs without shifting, check your motor mounts, which your mechanic should have done, but check them anyway. Can do this from above or below, jack the engine and look from above for relative motion, or inspect the mounts from below as you jack the engine.Digital Point modules: Sphinx-based search.

This may reset the engine control unit and the transmission malfunction message may turn off. It doesn't always work but it is worth a try. There is a high chance that you will experience the same transmission problem again. This procedure is very simple, requires no tools, and only requires a couple of minutes. For the next few driving cycles, your BMW will be monitoring your driving patterns; do not drive aggressively. With a BMW scanner, you can perform a full system scan. If you use a generic OBD2 scanner you will get generic fault codes such as P0720 or P0732 which don't provide enough details on what could be the cause of the problem. It is possible that a fault code can put your BMW automatic transmission in Fail-Safe mode even if there is nothing wrong with the transmission. As the level is low, there is no transmission fluid for the oil pump which causes the transmission to go in FailSafe or Limp mode. Make sure to allow the transmission to shift through all the gears. Transition fluid temperature should reach around 100 degrees F. during this driving cycle. If the level is low, there will be no oil coming out. It is important to point out that there are a lot of discussions and often disagreements whether you should or should not change the automatic fluid in a BMW especially on a transmission that is sealed for life. If you are not going to flush the whole system but only drain the oil pan you need about 4.5 qt of oil.http://www.extrusiongroup.com/fckupload/craftsman-clamp-meter-73756-manual.xml If there is any oil the communication between the transmission control unit and the mechatronic valve body is interrupted. Remove the splash shield from under the transmission and unplug the wire harness. When this happens the fluid pressure at the mechatronic valve body is reduced. Aluminum Part Number SFC-MA-001 is available. These harsh upshifts and downshifts are often due to a TTC clutch failure, overheating, damaged solenoid, worn selenoid springs, and other problems with the mechatronic unit. If you have some basic DIY skills, you can replace the mechatronic unit on a BMW. Before you purchase a replacement mechatronic unit, check with the seller or BMW dealer if programming or coding is required for your model. Drive the vehicle around for about 15-20 minutes making sure transmission cycles through all the gears several times to recalibrate the shift points. These updates change the shift points which improves the shifting. Typically a BMW will go into failsafe mode if the voltage is under 9 volt. To verify that the problem is with the first gear, set your BMW transmission in Winter mode, which forces the transmission to start in second gear. Keep the transmission in winter mode, until you get your BMW transmission repaired. To verify that this is the issue, it is recommended that you stop your car and let it cool down. A check engine light may also come on. Symptoms often happened between 50-70 mph. This is often because the torque converter locks up, is wearing out, and not locking the torque converters. These messages vary between models, but they all point to problems with BMW transmission. Gearbox position P may not be available. Set parking brake when completely stopped. Engine start may be possible with a delay. Continued driving possible. Reduced acceleration.

Any ideas(poss software reload to fix?). Thanks. Joe Got an F25 N47 automatic transmission Sdrive. After replacing the engine control, the automatic transmission shifts to safe operation mode and reads the following error message (420321) does not shift in or out of 2 gears. Cables are OK.The measured voltage was 11.3 in the positive cables.I've already done the adjustment and calibration and nothing has improved. It was fine when I parked it the next morning my battery was dead I got a jump and boom it was in this mode.i did just read it is possible my battery stored some bad codes. My battery light does come on every time I hit the Has But then goes a way when i let up.Has this happened to anyone else. I hate to put my business out there but I don't have any money since my ex emptied my account 2 weeks ago. Won't be cheapest would be great. Thank you Thanks. Andy I was doing around 140mph and the trans went into limp mode. When i check to see if my battery was good it reads 14 volts running with no accesories. With all my acceseries running such as radio, fan, headlights and heated seats on it only read around 12 volts. Could my alternator cause this problem? Thanks a lot and best of luck My 2005 BMW X5 is doing the same thing and I have not been able to get any answers. Thanks so much! Had issues with alternator, charging etc. I put in a new battery. Also monitored voltage each day. I found it only started charging after a few miles. I got a replacement control module for the alternator. Also stopped all the oil leaks that were dripping onto the alternator. Now okay. My theory: Oil was leaking into the alternator. Overnight this would accumulate.https://eurodente.com/images/canon-powershot-s110-manual-focus.pdf So in the morning the oil, being an insulator, was stopping the alternator from charging properly until I had driven a few miles. By this time, centrifugal force had thrown off the oil and the alternator resumed charging. I turned it off and it cleared and has been fine for 5,000km then I had a transmission fault again today but no error code recorded on the DTC list. Does the transmission need to be programmed or recoded. I have 5hp19 trans It runs and drives great under normal conditions. I have noticed that If I really step on it causing it to hold in gear longer it will hesitate on shifts above 4k or so rpm and jerk a little. It seems to have an issue a higher rpm shifting to the next gear. I have not checked the fluid level yet nor do I know when the lats trans service was done. The car has just over 150k on it and was a well maintained 1 owner car. I did not notice this on the test drive since you really have to get on it to make this happen. It typically does not register as any sort of fault but did yesterday for the first time. I tried getting it up to around 5k in 4th gear (using the manual shift feature) and it seemed to not want to go into 5th, even though it said it had on the dash. I tried shifting again and it really didn't like that and immediately gave me an error message. I am assuming it tried to go into 6th gear from 4th and this is why I received the message. I reset it and the message went away. I plan on doing a filter and fluid replacement in the near future and was wondering if I could get any advice on what may cause this issue. Other than this the car up shifts and down shifts smoothly without issue under normal driving conditions. Thanks I've done transmission filter and fluid change it hasn't changed it. However after a few minutes it worms up and losses all drive. Let it cool down and it will drive again ? It went away completely when I replaced the two forward shift solenoids and did the band adjustment (4L30E GM transmission). Now there is a pause when I shift from reverse to Drive first thing in the morning then an occasional odd shift in D, but not in 3rd. Next I'll try resetting the Transmission and check fluid levels again just for good measure. I'll post an update if the reset helps. Electronic Transmission Control ModuleThings I've tried to fix this:So to look for leaks, loose wires and check trans fluid level.Great job on Wright up just as others have said.

The release bearing is designed to operate with minimum friction between the rotating and stationary points of contact. If noise develops from the bell housing area, a few checks can be done. Listen for noise with the transmission in gear and the clutch pedal to the floor. Next release the clutch with the transmission in first gear. Noise under this condition indicates a worn release bearing or a worn pilot bearing. If the noise persists, the release bearing is bad. If the noise is gone, the pilot bearing is bad. Check the clutch linkage for binding or mis-adjustments. Check clutch pedal free play and pedal reserve for proper setting. Check the clutch fork and input shafts for proper alignment.

Its stylish, understated looks, combined with a world-class straight-six engine and expertly tuned chassis dynamics, make it a true joy to drive. Despite the car’s rising status as a collector’s item, prices have remained reasonable over the years, meaning pretty much anyone can own one. Thinking about picking up an E46 M3 of your own. Great choice. Here’s how to get a good one. The Making of a Legend The E46 M3 was first shown to the public as a concept at the 1999 Frankfurt Auto Show in Germany, before making its debut as a production vehicle at Geneva the following March. Based on the standard 3-Series, it was longer, wider, heavier, and more powerful than its predecessor, the E36. In our initial 2001 test, we were able to clock a 0-60 time of just 4.7 seconds, and a quarter-mile of 13.3 seconds at 106 mph—not bad for a car that’s now two decades old. Under the hood sits one of BMW’s most iconic motors, the S54. An evolution of the Euro-model E36 M3’s S50B32 straight-six, it displaces 3.2 liters and made 333 horsepower and 262 lb-ft of torque when new. That’s thanks to things like an increased bore, new camshafts, a higher compression ratio, individual throttle bodies, and a VANOS (a German acronym for variable nockenwellen steuerung ) solenoid attached to the front of the engine that uses oil pressure to adjust cam timing. There’s also a one-piece aluminum head casting to save weight and an oil scavenging pump to keep oil flowing during cornering. This motor can also be found in the Z4 M and later versions of the Z3 M. A year into production, BMW added the second iteration of its Sequential Manual Gearbox (SMG) as an option for those who preferred shifting with paddles. In the rear sits a purely mechanical clutch-type limited-slip differential. Like most M-badged BMWs, the E46 M3 doesn’t actually look too different from a standard 3-Series of the era. Most of the changes are subtle, but easy to spot if you know what to look for. The fenders are almost one inch wider all around, with model-specific grilles found on both sides. There are bespoke side mirrors, wider kidney grilles, a quad-exit exhaust, and a raised “power dome” hood. Inside, the M3 got M-specific sport seats with side bolster adjustment, a three spoke steering wheel with M-colored stitching, an illuminated M-badged shift knob, M-specific gauge cluster, M3-badged door sills, and a handful of model-specific cloth and leather material. Although the car didn’t change much visually during its production run, BMW continuously added new standard features and options to keep things fresh. Bi-Xenon headlights became available in late 2001, while an in-dash CD player was added as standard. Starting in early 2002, a front strut bar became standard equipment, and buyers could option things like 19-inch forged alloy wheels and brushed aluminum interior trim. LED taillights, a bluetooth phone interface, and two new colors were added in 2003, while the steering rack was revised in late 2004. BMW offered the E46 M3 in just coupe and convertible body styles, despite one of the car’s main competitors of the time, the Audi RS4 Avant, coming in wagon-only form. An M3 Touring was, at one point, heavily considered for production by BMW, however. The company went as far as to have a single, complete, running prototype built. That prototype currently resides at the BMW museum. BMW’s decision not to put it into production hasn’t stopped people from building their own custom versions, of course. So Which One Is Right for Me. Which M3 suits you best will depend heavily on how much you want to spend, and how you plan to use it. If you plan to do any serious driving, like track days or autocross events, we’d suggest eliminating the convertible variant from your search. Sure, it’s always more fun to drive with the top down, but removing the roof means less structural rigidity, and a compromised experience behind the wheel. Plus, many HPDE organizers won’t let convertibles without fixed roll bars to participate, and the E46 doesn’t have any.If it were us, we’d get the manual. It makes the car a better experience, no matter what you plan to use it for. Thinking about making an E46 M3 your dedicated track or autocross machine. We’d suggest finding a manual coupe that’s had all of the common maintenance issues (addressed in the next section of this article) taken care of. The last thing you want is something expensive failing while you’re out on track. It might cost you a bit more up front, but in the long run, it’ll likely save you a lot of trouble. It also may be worth it to go one step further and find a car that’s already been prepped for the job, with things like a roll cage, aftermarket seats, a more aggressive suspension, better brakes, and stickier tires, if you really want to save some cash. What About Maintenance. Like most German performance cars, the E46 M3 has its fair share of known issues, some more serious than others. If you’re inspecting one for sale, it’s important to know what to look for, and what sort of work has been performed before you buy. BMW issued two engine-related recalls for the M3. The first, affecting 01-03 model-year cars, had to do with the connecting rod bearings that hold the piston rods to the crankshaft. They were incorrectly sized at the factory, leading to oiling issues which caused premature engine failure. By now, most of the cars affected have either had the recall done, or had their engines replaced, so it’s no longer as prevalent an issue as it used to be. But just to be sure, we recommend checking the VIN with your local BMW dealer to see if the car in question has had the work done. The second recall had to do with improper seals on the VANOS solenoid, and wasn’t as widespread. A cracked or torn subframe mount means the subframe itself can shift while the car is on the move, making the car unpredictable to drive. The most important thing to do when buying a used M3 is get a good look at these mounting points to see if there’s any damage, or if any repairs have been done. Bring a floor jack if you have to—this could cost you thousands in repairs if you miss it. If, for whatever reason, you’re interested in buying an M3 with the SMG transmission, know that the pump that actuates the gear changes is known to fail, and costs a lot of money to replace. Clunky gear changes are normal, but if you find on your test drive the paddles won’t respond to your commands or the transmission is shifting especially slowly, it could be in need of a replacement pump. Well, like any car, as M3s accumulate miles, more “old car” problems will start to appear, like worn bushings, cracking rubber, and failing seals. It’s best to check over all of those things should you do an inspection yourself—though we’d recommend spending a few hundred bucks on a proper pre-purchase inspection using a BMW specialist shop, if you can. Also, keep in mind the S54 uses expensive 10W-60 oil, so oil changes won’t come cheap. What About the Community. The E46 is one of the most successful M cars of all time, with over 43,000 examples sold in the U.S. alone, according to the BMW M registry website. As such, there’s an active collection of past and present owners on call to answer pretty much any question you might have about the car, and give unique insights on what it’s like to keep an M3. Clubs and online forums are a great way to interact, with organizations such as the BMW Car Club of America setting up meets, track day events, and group drives across the country. We recommend joining if you want the full BMW experience. Check out the rest of our buyer's guides right here ! You may be able to find more information about this and similar content at piano.io. GM's 5 speed automatic transmission was used widely between 2000 and 2007. BA Transmissions The GM 5L40-E transmission is very common in cars of a certain age and, as those cars continue to age, more and more of them are finding themselves in the shop for transmission faults. Fortunately, because the 5L40-E has been around for some time, a lot of the faults you’re likely to find are well known and understood, and in this article we’re going to look at some of them. Please be aware that this article assumes some (but not a lot of) working knowledge of cars and terminology. The GM 5L40-E Automatic Transmission: A Brief Overview Before we get into the faults and foibles, I thought I'd include a little bit of background information on this transmission. I've also included a nice video overview below. The GM made 5L40-E (sometimes referred to as “A5S360R”) automatic transmission is a five-speed transmission that saw common use between 2000 and 2007. There are many vehicles that use the 5L40-E, but some of the more common instances include the BMW 5 Series (E39), L322 Range Rovers, and a range of Cadillacs—check the end of this article for a more comprehensive list of vehicles. It features five forward gears and one reverse, with 4th gear being a 1:1 ratio and 5th gear being “overdrive.” The 5L40-E can come in both two- and four-wheel drive flavours, though many of the components used are the same or very similar.If your transmission seems to slip first thing in the morning, or when it's been sat unused for a while, it’s probably a bit low on transmission fluid. As the transmission warms up the oil thins out and expands which, in turn, raises the fluid level, but when it’s cold the fluid level is lower. If the level is low enough, the transmission might struggle to get enough fluid to apply the clutches, hence the slipping. If this is your problem, you can perform a temporary fix by topping up the oil level; however, I must stress the “temporary” part. If your 5L40-E is low on transmission fluid, that fluid must have escaped somewhere, and if you don’t plug that leak, you’ll be topping up your transmission fluid indefinitely.Common places for leaks to occur are around the sump (metal pan underneath the gearbox), from the rear seal around the output shaft, or from the pump seal. Unfortunately, a leaking pump seal would require the removal of the transmission to remedy. This does tie in nicely with the next fault, however. Behind the pump seal is a bush that is responsible for keeping the torque converter steady and central as it spins. In this particular transmission, they seem to wear down relatively quickly, allowing the torque converter to “wobble” slightly. In addition to certain driving issues such as a juddering sensation, this “wobble” squashes the seal out to the point that it begins letting transmission fluid through. The best case scenario here is that you catch the problem early and “only” need to remove the transmission from the vehicle, remove the front end of the transmission, dismantle the pump assembly, and replace the bush and seal. However, in some cases, this issue can cause damage to the torque converter neck and even the pump itself, and replacing those parts is sure to run you up into a four-figure bill! If it's leaking from the front, it has to come out. As mentioned above, the transmission fluid expands when it heats up. This not only causes the oil level to rise, it also causes it to become thinner. Automatic transmissions employ a lot of pressurised components that maintain their pressure through a variety of seals and valves. When those seals start to wear, transmission fluid can escape, lowering the pressure. In cases where a transmission is worn but not completely gone, it may drive fine when the oil is cold and viscous. When that oil heats up and thins out, it can start finding its way out of these worn seals and valves, causing a lack of pressure when applying a clutch. Unfortunately, when this happens, there’s not much to be done below a complete rebuild that can cure the problem.Attempting to do so will almost certainly damage the pistons. Worse still, the entire drive of the vehicle passes through this shaft, so when it wears down, the vehicle no longer drives at all—and tends to make a horrendous racket when it tries. The shaft is connected to a drum inside the transmission, and as the drum is at the back of the gearbox, not only do you need to remove the transmission to replace it but you also need to take all of the guts out of the gearbox to get to it. The one silver lining here is that the wear of this shaft is external to the transmission, and will not cause any damage to the rest of the box. Replacing the output shaft and sliding into a half worn transfer box will not end well. If the oil were just shot into that chamber all at once, the clutch pack would apply with a harsh thud and make for a very unpleasant driving experience. The 5L40-E gets around this problem with the use of a number of accumulators which allow the oil to be fed in gradually until the pressure is sufficiently high. The accumulators work by sitting a small sealed piston on top of a spring so that when the oil is fed into the chamber, it pushes the piston against the spring. These springs, however, have a nasty tendency to break. Fortunately, repairing this problem is (relatively) easy. You don’t need to remove the transmission, just the valve body which can be found inside the sump at the bottom of the transmission. If the gasket rips, the valve body has to be completely stripped down to replace it. The accumulator spring on the far right has broken in two. Range Rovers.net Complete Loss of Drive Symptoms Partial or complete loss of drive The most common reason for a vehicle running a GM 5L40-E transmission to end up in a transmission repair shop is torque converter failure. For a variety of reasons (torque converter solenoid, worn valves, worn converter) the converter fails and begins contaminating the oil with debris. The debris circulates throughout the transmission and, eventually, begins blocking the filter. Once the filter is clogged up, the clutch packs are starved of oil and begin to slip. The slipping clutches begin to burn up, further contaminating the oil with debris and, well, you get the picture. For most motorists, however, nothing less than a full rebuild and replacement converter will remedy the problem. The easiest way to check for this problem is to remove the sump and check for debris. If the converter has failed in this fashion, the sump will be full of metallic debris. Many transmission builders just replace the cooler to be on the safe side. BA Transmissions Please remember that this article is only detailing the most common problems with the GM 5L40-E transmission, and the most common causes of those problems. There are other faults and there are other causes of these faults—they’re just far less common. Vehicles Using the GM 5L40-E Automatic Transmission Though I'd never be so bold as to claim this to be an exhaustive or complete list of vehicles, it is a fairly comprehensive one. Please be aware, however, that there are always exceptions, such as cross-over years where a manufacturer moved from one transmission to another, and even modified cars where a previous owner has fit a different transmission. The L322 version of the Range Rover is one of the more popular vehicles to utilise the GM 5L40-E automatic transmission. Ron ooke on December 18, 2019: Have an older Rolls fitted with the GM box I have fluid pushing out of the dip stick please advise where the breather is situated so I can check if is blocked Chris on October 30, 2019: Hi John, We have a 2004 bmw e46 with the 5 speed gm auto box. The gearbox works fine up and down through the gears except there is a slight shudder at about 40mph. We have been quoted 1000 pounds to replace just the torque converter or 2400 pounds for a complete overhaul plus vat. What should we do? Claudio on May 31, 2019: My GM has always worked fine until this morning. Now at the present moment I started the engine and when selecting gears the car does nothing. Switched it off, allowed me to go back but no drive so I left it at home. I have a e39 530d touring. Can you give me the real scenario I am facing I have knowledge of how the tranny works, just in the selector shaft have a small leak behind the engine near the floor pans. Is it low in ATF or the torque converter is gone. I am from Portugal, we have a huge heat wave right now of over 33.C so I am puzzled why having this afternoon nothing to move the vehicle at my door step. Percival Spence on March 28, 2019: I have a BMW x3 with a GM 5L40-e transmission i am trying to get the neutral saftey switch and i cannot get the pin out even figure out how to remove the rod holding the switch could you please give me any assistance on how to do this. Mohamed on February 02, 2019: Dear sir I have a problem in my car BMW e46 n42 318i 2002 The problem is that when I drive my car at after it’s been stop for hours, the first and second speed go fine, however, when it comes to the third speed the red cog light flash on the dashboard, which mean there is a problem in the transmission “gearbox 3”. Some people told me that this happens because there is air leak in the vacuum lines.
