89 corvette manual transmission fluidThe expense is great and a lot of things can happen to your car while it’s in the shop. Make sure you find a top quality shop. The quality of the work is going to be a lot more important that final price. Most Corvette owners prefer the automatic transmissions to the manual transmission. This means that most of you reading this article have an automatic transmission in your Corvette. These are very solid transmissions and seldom need repair. The most common reason for repair is simple abuse and the most damaging abuse comes from neglect. You can make two very simple checks. First, you should check the fluid level. Make sure you do this when the car is completely warmed up. Also, make sure you always check the car with the engine running. On the other hand, after twenty years in the service business and a few years with a major transmission chain, I have to point out that very few people know how to properly check the level of the automatic transmission fluid. Low fluid levels are a major reason that automatic transmissions have to be repaired. High speed driving will give you a false reading on the dipstick, or as GM calls it, the fluid level indicator blade. Wait at least three minutes with the car in Park before you check the fluid level. After you remove the dipstick place it on a white paper towel. The fluid should soak into the towel fairly easily.Just for comparison drop some brand new Dexron III ATF fluid next to the spot being checked. This will give you a good side by side comparison of how drastically your fluid may have changed since it was last serviced. I’m a fanatic about regular fluid and filter changes for an automatic transmission. I recommend that you change it on an annual basis even though that may be a little excessive. There’s a good chance that the dirt and crud inside your transmission is what’s holding it together. At this point any possible damage has been done and changing the fluid and filter might only make things worse.http://www.ferruccigroup.it/userfiles/del-sol-hot-tub-owners-manual.xml

Just start putting money aside for a rebuilt transmission. Changing the automatic transmission fluid in a Corvette requires dropping, or removing, the oil pan. Some shops use transmission service equipment that can replace the fluid without dropping the transmission pan. This equipment either taps into the ATF oil cooler lines or connects to the dipstick filler tube. The problem with this approach is that the service doesn’t include a filter change. The only way to change the filter is to drop the oil pan. You should be more concerned about changing the filter than you are about changing the fluid. The higher the car is off the ground the easier this job will be. Next I would put some large plastic sheeting on the garage floor. Make sure that you spread it the width of the entire car and possibly three feet in front of and behind the transmission. Just assume you’re going to make a mess. It wouldn’t hurt to have a bag of kitty litter handy as well. They may be either boxed or in flat shrink-wrap packages. Flat shrink wraps are typically used with cork pan gaskets to protect the gasket from bending that could damage it. Rubber (neoprene) pan gaskets, on the other hand, are flexible and can be folded to fit in a box. Different technicians have different preferences as to which is the best gasket material to use. Silicone gasket material can cause you more problems than you can imagine. When you use silicone gasket material it’s squeezed between the transmission body and the pan. You’ll notice how it squeezes out of the sealing faces. Just keep in mind that just as much has been squeezed into the oil pan area. If this material gets loose inside the pan there’s a very good chance it will find it’s way into internals of the transmission and clog a very important passage. The transmission’s fluid capacity is important because automatics must be run very close to the full level, and never over that level.http://www.kantoromega.pl/userfiles/del-liftgate-manual.xml Overfilling your automatic transmission can aerate the fluid causing shifting problems. Underfilling can cause slow engagement and slipping. The amount of ATF required is usually listed in the vehicle owners manual. Also, make sure you read the dipstick properly. It’s dark under your Corvette and you want to make sure that you see everything that’s going on. This is one case where those inexpensive halogen lights carried by Home Depot come in very handy. They focus the light directly into the correct area. You only need to worry if you find lots of fiber material and big chunks of metal. Just continue on the task and remember to start setting some money aside for a rebuilt transmission. None of them are good for your transmission. The only time I would use and additive is out of desperation. A case in point is where the seals have started to leak and you want to postpone any real repair. The additives designed to stop leaks contain chemicals that swell the seals and gaskets to reduce fluid leakage. This might hold you over until you can reduce the balance on your Visa card so your transmission can be properly repaired. Just don’t think of it as a real repair. The large transmission shops always keep a variety of units on the shelf. That’s how they can offer same day service on a transmission repair. Since the transmission used in the Corvette is popular across the GM product line they may have a couple on the shelf. Then just to be on the safe side crawl under the car with a light and locate the VIN number on your transmission. This VIN number can be in more than a half dozen locations so check carefully. Then when you get your car back home check this number again. Just ask the people who own 1968 and 1972 Corvettes how much they would be willing to pay to get the original transmission back in their Corvettes. Having the original driveline in your Corvette will become a big deal at some point. Don’t neglect it now. It may sound a little silly if you know what you’re doing, but on the other hand fluid neglect is the single largest cause of transmission failure. Make sure you read the dipstick correctly and that you also check the condition of the fluid at the same time. You really won’t look all that silly with your nose on the dipstick to check for a burning smell. You’ll feel a lot sillier if you have to get a home equity loan to pay for a new transmission in your Corvette. The Vehicle Identification Number could be in any one of six different locations. Just keep looking until you find the numbers. While you’re under the car you can also copy down the Identification Code which has a lot of interesting information once you decode the letters and numbers. It was still a 4-speed transmission and it still had fluid and a filter that needed changing. All of the changes were part of the quest for improved fuel mileage and smoother shifting. Actually, if you look around a transmission shop you’ll most likely find a variety of different materials. The real secret to keeping your transmission oil pan from leaking is to make sure that both surfaces are very clean and you use a torque wrench to tighten the oil pan bolts evenly, using a variation of the star pattern you use when tightening lug nuts. When your transmission is rebuilt everything comes out of the case and then parts are checked, replaced and everything goes back in as a stack Some shops only repair the first broken item they find and stop. Everything is put back together and they hope it holds long enough for the check to clear. Stay away from that sort of shop. Ask questions and shop around.

I’m fairly handy around cars (such as installing new head gasket in GM v6), but I don’t have lift for the corvette to get under to attempt the trans fluid change. So should I try changing the trans fluid and filter to if it cures the issue. Or just take it into shop that can rebuilt the 3-4 clutch pak. I adjusted the tv cable and the low gears shift much smoother. Please also give advice. Shaking stops when the foot is removed from the gas. We don’t know where to look for a mistake. Please help. Thanks Josef The transmission goes into drive and reverse hard. I will check the fluid as well as the TV cable.Thankyou for the suggestions, most helpful. On occassion and quite unexpectedly whilst driving normally, the car will not change up and out of 1st gear and then when pushing the revs without an increase in speed she will then change suddenly and jolt forward and the change into the next gear will then be successfully achieved. Then after limping to my destination in first gear, and when the car is stationary for about an hour or so, the transmission will again behave quite normally and the shifting through the gears will be very smooth once again. As I mentioned this is an occassional problem and my driving the car yesterday presented absolutely no problems whatsoever. Could there be an intermitant problem be with one of the shift sensors. I would appreciate receiving your valued response C5 started in 97 It goes in gear until it gets up to running temperature than it doesn’t go into gear again can anyone help If this is OK, It could possibly be an issue with the T.V. cable. Refer to section 7A (automatic transmission) in your GM Shop Service manual. It states that if the T.V. cable is broken, sticky, misadjusted, or the incorrect part for the model, the vehicle may exhibit various malfunctions. Be sure the transmission oil level is correct, inspect the cable for damage and proper attachment, then consider adjusting. There is a “re-adjust” tab on the cable back from the throttle lever attachment. Depress the re-adjust tab. Move the slider back through the fitting, away from the throttle body until the slider stops against the fitting. Release the re-adjust tab. Open the throttle lever to “full throttle stop” position to automatically adjust cable. Release the throttle lever. Do not use excessive force when adjusting the T.V. Cable. If excessive force is required to adjust cable, it most likely needs replaced. In the 89 corvette? 700r or is a turbo 350 thanks. Shift changes are correct also fluid level, what are your thoughts? Did you find the cause? It was quite informative. I have a 1987 Corvette convertible with 53,000 miles. It drips transmission fluid but the mechanic cannot find the source. He has dropped the pan, changed the fluid, filter and gasket and torqued the bolts according to specs. He says there are no leaks around the pan. Is there someplace else the fluid can be leaking from? In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page.

With each passing model year, on-going modifications to the engine, drive train, suspension and steering had transformed the C4 Corvette from a car that was recognized more for its handling than its performance into a machine which had successfully mated technology and horsepower. With fuzzy spy photographs and a growing rumble amongst the Detroit automotive community, there had been a growing speculation that a new “King of the Hill” Corvette was on its way. Chevrolet neither confirmed nor denied the rumors, at least until the 1989 Geneva Auto Show, when the ZR-1 was officially debuted. Boasting an incredible 375 horsepower LT-5 engine (which had been developed by a team of engineers led by Lotus’s former Technical Director Tony Rudd ), and a fully redesigned performance package, the car achieved an almost instant legend status amongst both Corvette enthusiasts and automotive critics alike. Additionally, General Motors employed a Good Year test track in Mireval, France to show off the new supercar’s performance and improved handling abilities in a series of high-speed and wet-pavement tests. Within days of its unveiling in Geneva, the ZR-1 owned the cover of virtually every magazine in the world. It was featured prominently in publications such as Germany’s Auto Motor und Sport as well as England’s Car and AutoCar, to say nothing of the assorted American publications which hosted the new ZR-1 as their cover story. While both the media and Corvette fans vehemently protested the announcement, GM gave the reasoning that there was “insufficient availability of engines caused by additional development.” Eighty-four 1989 ZR-1 Corvettes were built for evaluation, testing, media preview and photographing, but no 1989 model ZR-1’s were made available for public purchase. The first significant improvement to the Corvette in nearly half a decade involved the introduction of an entirely new manual transmission for the 1989 model year. When operating the Corvette in low throttle conditions (anything under 35 throttle) or at speeds of between twelve and nineteen miles per hour, the CAGS system would lock out second and third gears, forcing the driver to shift directly from first to fourth. This feature, combined with a monumentally tall sixth gear for highway cruising, would help to keep the Corvette out of the EPA’s records. For the series, Chevrolet built sixty cars, thirty of which would have their stock engines swapped with higher-output engines from the CPC (Chevrolet-Pontiac-Canada group) engine plant in Flint, Michigan. At the end of the series, Chevrolet returned the original, numbers-matching engine to each of the Corvette race cars. While the Z52 option had been optional in previous years, it was now made standard on all models of the 1989 Corvette. For 1989, seventeen inch wheels and tires replaced the smaller, sixteen inch wheels which had been used on the C4 Corvette since 1984. For cars that were equipped with the new six-speed manual transmission, Chevrolet standardized the heavy-duty engine oil cooler, the heavy-duty radiator and the auxiliary radiator fan. RPO FX3 featured a selective ride and handling package.These, in turn, operated rotary valves that controlled the flow of fluid into the pistons. The system monitored and adjusted itself ten times per second and functioned during compression as well as during rebound. Within each setting, the damping rate increased with the car’s speed in six, twenty-five-mile-per-hour steps, from 25 miles per hour to 150 miles per hour. When set to touring, the suspension would partially absorb ruts and pot-holes on back roads whereas when set to performance, the Corvette was effectively transformed into handling like a race car. Both the cloth, the standard leather and the more expensive sports leather material options remained available, though the leather was restricted to cars equipped with the Z51 option. A cloth headliner and window weather-stripping were included, as well as an electrically heated rear window (which plugged into a special rear-deck socket.) For consumers that preferred the factory soft-top, the convertible mechanism was simplified for easier operation. Even with the knowledge that the ZR-1 Corvette’s arrival was certain in 1990, Chevrolet sold a total of 26,412 Corvettes in 1989, of which nearly 10,000 units were convertibles. Each Vehicle Identification Number (VIN) is unique to an individual car. The 5hp increase came from less restrictive mufflers which were deemed too loud for convertibles and 2.59:1 axle coupes. Due to weight and fuel economy factors, Chevrolet intentionally limited sales of the sports leather seats by making them available exclusively with Z-51 optioned models during the 1989 model year. Due to weight and fuel economy factors, Chevrolet intentionally limited sales of the sports leather seats by making them available exclusively with Z-51 optioned models during the 1989 model year. The cars were then drop-shipped to Callaway’s Connecticut shop for installation of Callaway-modified twin-turbo engines. The Callaway Corvette could be ordered through participating Chevrolet dealers. Fully assembled Corvettes were then shipped from the Bowling Green Corvette plant to Callaway Engineering in Old Lyme, Connecticut, where it received engine (and other) modifications. Later production with Z52 had Z51’s larger front brakes, less restrictive mufflers, longer air dams, and steering coolers because option B2K triggered these through Special Equipment Option Z5G. The Z52 springs and stabilizers provided for a greater range of suspension control. The G92 Option was available when ordering either the Corvette or the Camaro throughout the 1980’s and early ’90’s.

While the intent of this page is to identify the common issues pertaining to the 1989 Corvette, it is not an all-inclusive list and should be used for reference only Intake and Exhaust Manifold gaskets are known to leak and will require replacement. In either case, the rear tie rod breaks, causing the right rear wheel to pull the car off road to the right. This malfunction can occur without warning, and often while during vehicle operation. This same problem is known to exist in 1988 Corvette models as well. The common problem is that the brake pedal itself depresses completely to the floorboard with no brake response. Probable cause is a defective master cylinder or a leak in the brake system. Braking system can also cause erratic braking conditions which have resulted in loss of vehicle control. The Anti-Lock Braking System may lock up during vehicle operation causing the vehicle to skid out of control. When the catalytic converters deteriorate (either from age, usage, or both), the upstream converters literally disintegrate internally, and the deteriorated material may pass through the exhaust to the downstream converter, creating a blockage the can affect horsepower and performance. If this happens, the converters must be replaced to restore power to the car. Battery requires recharging before vehicle is operable. To correct this issue, the computer ECM must be replaced.Multiple cases have been reported of rims being warped simultaneously during vehicle operation, resulting in a bad shimmy between 35-55 miles per hour. If the computerized dashboard is diagnosed as defective, the entire dashboard assembly must be replaced. GM issued a factory recall for this item. Check all button locations. Also, if a brake warning light comes on or flashes, or the anti-lock (if equipped) comes on or remains on, something may be wrong with part of the braking system. Have it inspected and repaired at once. These are signs the system may be leaking or overheating. Also see “Engine Exhaust Gas Caution (Carbon Monoxide)” and “Catalytic Converter” in your Owner’s Manual. This may mean a wheel balance is needed. Also, a pull right or left on a straight, level road may show the need for a tire pressure adjustment or wheel alignment. An inspection is needed when the steering wheel is harder to turn or has too much free play or if unusual sounds are noted when turning or parking. If beam aim doesn’t look right, headlights should be aligned. See your Owner’s Manual for further details. NOTE: A large loss of oil in this system may indicate a problem. Replace if dirty or rusty. See your Owner’s Manual for further details. NOTE: A large loss in this system may indicate a problem. Have it inspected and repaired at once. Pressure should be checked when tires are “cold”. Water dripping from the air conditioning system after use is normal. If you notice fuel leaks or fumes, the cause should be found and corrected at once. NOTE: A large loss in this system may indicate a problem. NOTE: A low fluid level can indicate worn disc brake pads which may need to be serviced. All others, check clutch pedal free travel and adjust as necessary. See your Owner’s Manual for further detail. Have it inspected and repaired at once. NOTE: A large loss in this system may indicate a problem. Also, check for damaged wheels. To equalize tire wear and obtain maximum tire life, it is suggested that tires be rotated at 7,500 miles (12,500 kilometers) followed by 15,000 miles (25,000 kilometers) thereafter. See “Tires” in owners manual for further information. Inspect disc brake pads for wear and rotors for surface condition. Also inspect drum brake linings for wear and cracks (if applicable). Inspect other brake parts, including drums, wheel cylinders, parking brake, etc.Inspect boy near the exhaust system. Look for broken, damaged, missing or out-of-position parts as well as open seams, holes, loose connections or other conditions which could cause a heat build up in the floor pan or could let exhaust fumes seep into the trunk or passenger compartment. Adjust or replace as needed. Cars equipped with limited-slip differential should have gear lubricant and any required additives drained and refilled at 7,500 miles (12,500 kilometers). See your Owner’s Manual.Have it inspected and repaired at once. The proper lubricant should be used. Make sure the recliner is holding by pushing and pulling on the top of the seatback while it is reclined. See your Owner’s Manual for seat operating information. Make sure the spare tire, all jacking equipment, any tire inflator and any covers or doors are securely stowed at all times. Oil jack ratchet or screw mechanism after each use. Also lubricate the body hood, fuel door and rear compartment hinges and latches including interior glove box and counsel doors, and any folding seat hardware. Then, firmly apply both the parking brake (see your Owner’s Manual for procedure) and the regular brakes. Do not use the accelerator pedal. If the engine starts, be ready to turn off the ignition promptly. Take these precautions because the car could possibly move without warning and possibly cause personal injury or property damage. On automatic transmission cars, try to start the engine in each gear. The starter should crank only in “Park” or “Neutral”. On manual transmission cars, place the shift lever in “Neutral”, push the clutch halfway and try to start. The starter should crank only when the clutch is fully depressed. The key should turn to “Lock” only when gear is in “Park” on automatic or “Reverse” on manual transmissions. On cars with key release lever, try to turn key to “Lock” without depressing the lever. The key should turn to “Lock” only with the key lever depressed. On all vehicles, the key should come out only in “Lock”. To reduce the risk of personal injury or property damage, be prepared to apply the regular brakes promptly if the car begins to move. To check the parking brake, with the engine running and the transmission in “Neutral”, slowly remove foot pressure from the regular brake pedal (until the car is only held by the parking brake.) To check the automatic transmission “Park” mechanism holding ability, release all brakes after shifting the transmission to “Park”. Take care to thoroughly clean any areas where mud and other debris can collect. Sediment packed in closed areas of the vehicle should be loosened before being flushed. If dirty or rusty, drain, flush and refill with new coolant. Keep coolant at the proper mixture as specified in your Owner’s Manual. This provides proper freeze protection, corrosion inhibitor level and engine operating temperature. Inspect hoses and replace if cracked, swollen or deteriorated. Tighten hose clamps. Clean outside of radiator and air conditioning condenser. Wash radiator filler can and neck. To help ensure proper operation, a pressure test of both the cooling system and cap is also recommended. His fascination with speed and fast cars was first fueled by his grandfather, who would frequently take him to car shows or to the local race track. In college, Scott studied automotive technologies, and would spend his formative years working for a Chevy dealership - where he developed an obsession with the Corvette - an obsession that he is still passionate about today.

Next, how easy would it be to change it. Good enough for a home mechanic. We do our own brakes and oil etc. If not, how expensive would it be and where to go. Lastly, I've noticed that it randomly goes into overdrive, and won't go when I push the button. And sometimes like 5 minutes after. Occasionally it'll pop out of third, and I'm pretty sure it's not user error. Its happened to my dad. I don't notice any clutch slippage, and the last owner replaced it a couple months before I got it about 6 months ago. Since I don't know what you know, the trans is two components and has the gearbox and the overdrive. The gearbox will run fine on straight 80W-90 gear oil. I use valvoline synthetic off the shelf at most stores. There is no way to check it. You drain it from the lower plug and then fill it until it flows out of the upper plug. The overdrive runs ATF Dextron III specifically, I think there are a few different Dextron levels. The overdrive has a breather tube but does not have a way to check it also. You drain the overdrive by removing the pan, clean everything up and then reseal it with a gasket and rtv (filter replacement is a good idea at this time also). You fill it up from a plug on the side of the overdrive and stop when it overflows. The only difficulties with changing these fluids is if your exhaust setup is in the way or not, otherwise it's very doable. As for automatically going into overdrive and popping out of third.Maybe when it kicks out of overdrive it jars the trans enough to let it slip out. My overdrive kicks in smooth but lets off harsh if you dont use the clutch. I typically leave the overdrive shut off.RTV will work fine for the gasket. All rights reserved Back to top. Double-check your spelling or try a new search. Manual transmissions use a variety of oils: regular motor oil, heavyweight hypoid gear oil or even automatic transmission fluid in some cases. Your owner's manual will tell you what your transmission calls for. Letting your car run low on transmission fluid can cause the transmission to shift improperly - or even not at all.
