Tranny and Rear End Oil Changes
1.0 Six Speed Transmission (Getrag from Germany)
The Supra Twin Turbo six speed transmission by Getrag of Germany is one of the most durable transmissions ever manufactured for any production car, period. It also cost $7,000+ from Toyota and has NO replacement parts (although we are able to get them). That means if you blow this tranny, you CANNOT have just anyone rebuild it, you must buy a new one or used one ($5000+) or have our rebuild service done.
This transmission is notorious for its "rattling noises" being transmitted through the "dual mass" Toyota flywheel. Toyota from the factory recommends two types of oil that are both supplied by Toyota. One is $30 a quart (takes ~2) and the other is $90 quart.
Purchase an oil fluid pump at your local autoparts stores (cost about $10.00), so you can pump the oil in from your bottles of oil.
We at SupraStore.com recommend that you go with the factory OEM fluid. It has the correction friction modifiers and has proven to be an excellent product for this six speed tranny. A Supra owner has noted that Getrag does not recommend Redline D4-ATF or any other product which utilizes a "seal swelling" additive as it can cause issues with certain polymers within the transmission.
Changing the oil is as simple as removing the filler bolt first, then the drain bolt. When completely drained, wipe the bolt clean and sealing surface area and re-install the drain bolt (bottom of pan). Add the first quart, then begin to add the second quart until the oil start to drip out of the filler hole. Replace the filler bolt and you are on your way.
Change this oil every 30,000 miles or so.
2.0 Automatic Transmissions
This process is a little more involved. It's almost impossible to do a complete fluid change in an auto trans without removal, as much of the fluid is not just in the sump, but also in the lines, the cooler, and especially the torque converter. Usually the best way to tackle this is to drop the pan (since you should also replace the transmission filter as well), put back as much fluid as was taken out, and drive for a few days or few hundred miles. By then, the fluid should be a mixture of the old fluid and the new fluid. Repeat the process of draining the fluid--although you may refill at this point via the transmission dipstick. You still won't have all of the old fluid out, but a majority of it should be new and you should notice a difference immediately.
3.0 Rear End Oil Changes
The Supra rear end uses 75w90 gear oil and we at SupraStore.com recommend Redline once again. First remove the filler bolt (closer to top) and then remove the drain plug on the bottom. Install the drain plug after wiping clean the magnetic bolt (don't be worried if you have some metal on the bolt, that is why there is magnetized bolt in the first place and not uncommon regardless of vehicle). Re-fill using your oil pump with 1.6 quarts of oil and then re-install your filler plug. The MkIV does NOT require any special friction modifiers, as the factory LSD is a Torsen. Clutch type LSDs (such as TRD, OSGiken, etc.) DO require special modifiers however. Consult with the manufacturer of each for the recommended fluid type.
Change the rear end oil every 30,000-50,000 miles for comfort sake, even though it may well last longer.
