Important: Steps 8-13 are for vehicles equipped with the differential cooling system. Note 2: To properly flush the rear differential remove the left differential cover and get all of the old fluid out off the differential, wipe out the residue replace the cover o-ring and then reinstall the cover and fill with the appropriate amount of fluid and friction modifier additive. Fuel injected engines need careful inspection of the inlet air. When you add or change transmission fluid, be especially careful to use the correct designation fluid. The fluid should also run out when the unit is filled. When that temperature is reached, remove the drain plug and see if any fluid comes out. Tighten the differential drain plug to 35 Nm 26 lb ft.
I found this set up to be too short and too small a diameter, plus after a while the nozzle gets oily and the hose starts slipping off the nozzle no matter what you do. There are only two ways to solve it eliminate chatter and they both require a lot of work if the oil is not doing the trick. Many consider this an important step so do not overlook it. Changing the oil is paramount and synthetics are beneficial for engines, transmissions, and differentials. If that was not enough, the clutch application systems use the low viscosity clean fluid for proper shifting.
Once the differential fluid has been changed, the vehicle must be driven in 8-10 tight figure eight maneuvers to heat the fluid and allow the additive to be worked into the clutch plates. This FloTool fit really nice and made the oil fill a breeze. Bearings in place of bushings lower the friction of the shift rail movements for the Corvette, making the shifter feel naturally lighter and more direct. Do the drain, replace fluid and new filter service. I too have seen instances of failures after flushing but only in cases where the maintenance was put off until it was too late.
We use synthetic transmission fluid in all of our vehicles because of the heat load they must endure. With the proper tools, replacing the fluid is a straightforward process that helps keep this high-performance transmission running smoothly. If you need a little more help jump over to Smokinvette. Since you need to access the rear axle from the rear, you cannot block the rear with a jack. In the 1998 service guide I have on hand, the clutch bleeding procedure is also covered in section 7, sheet-351. Without the slipping clutch plates during cornering, the tires would chirp the tires while rounding every corner.
See fluid amounts listed below. Keeping the oil away from the reciprocating components and out of the cylinder walls lessened friction, thus saving fuel. Note 2: To properly flush the rear differential remove the left differential cover and get all of the old fluid out off the differential, wipe out the residue replace the cover o-ring and then reinstall the cover and fill with the appropriate amount of fluid and friction modifier additive. Add oil to the differential until oil starts dripping out of the axle oil fill hole. If your tranny fluid is muddy looking, a flush just might put your transmission over the edge and an overhaul is probably a better idea but if your changing the fluid every thirty thousand miles a flush shouldn't hurt it.
The wrench will barely go between the body panel and the bottom panel. A regular maintenance doesn't get the fluid out of the torque convertor. Changing the oil and filter will take care of the acids. For 100K items I usually cut the numbers in half to 50K and then do the maintenance. Install the drain plug and washer to the differential. Z06s have differential coolers base C6's do not and require a bit more effort.
Short trips on the other hand exacerbate the production of condensate that causes corrosion over time, making fluid changes every two years an excellent idea. What needs to be done is to have the car elevated and level. Changing transmission fluid every two years is a good rule of thumb regardless of mileage. Add fluid until the recommended level is reached. When the trans is flushed, the fresh fluid, with fresh detergents, cleans out the oxidation, creating transmission concerns.
This is why replacing the fluid with new additive may only temporarily cure the problem. First, run the car a while to get the axle oil warm. Many race engines have pre-oilers forcing lubricants through the system before the engine is started. Tighten the differential fill plug to 35 N·m 26 lb ft. To protect your engine, the acids have to be removed or neutralized. Drain and refill the rear differential fluid using the procedure listed below. A transmission flush will only harm a transmission that is already damaged, but is working due to oxidation of the fluid.
Ready to give it a try? The transmission exchange machine has a clean fluid reservoir that we use to evacuate the pan before pan removal. Note in the photos that the socket wrench handle extends down through the middle of the aluminum cross member. One solution is to buy an aftermarket fill tube at the local auto store. Oil and grime is on top and all over the front of transaxel. Friction surfaces on the automatic transmission clutch packs clamp down onto gear sets to propel a Corvette. The latest technology uses a fibrous material on the blocker rings. See fluid amounts listed below.
