Automatic Transmission fluid, Automatic Transmission fluid for ST Options

[rapid36]

Hey guys i have a 94 Celica ST Automatic Transmission that i brought back to life after 3 years of sitting I drove it 3 years ago and it ran perfectly fine, but now that I brought it back to life I was doing some exhaust work on the car and every once in a while revving it up quite a bit to test the exhaust. Well after i was all finished with the exhaust i decided to check everything else, I checked the transmission fluid and saw that it was a little low, I saw that the transmission had d2 stamped on the drain plug (dexron 2 or dextron 2) and so just to be sure i consulted my Haynes book for it. It said to use dexron 2 or dextron 2. So ok now that i know what it needs i decided to see where i could buy some, I couldnt find any locally and only found dexron 3 or dextron 3. So I did my research online and 95% of the people said yes it is backwards compatible and 5% of people said that some cars such as the supra MUST have dexron 2 or dextron 2. So I went out and bought some dexron 3 or dextron 3 and poured in a quart, the level on the dip stick (while the engine is running) was now at an acceptable level, However I cant drive it now cause at 2.5k rpm and above and 900rpm and below i get torque converter shudder. It seems that i bought crap dexron 3 or dextron 3. Can anyone confirm that they did this with their car? does anyone have similar issues? Does the ST only take dexron 2 or dextron 2?

You can use Dexron VI in most older transmissions as well. It's synthetic and helps to keep the transmission cooler as it causes less drag than the older Dexron fluids. It costs more, but it's worth it on cars that can upgrade to it. Then again as it lasts longer and reduces the wear on your transmission it really pays for itself anyway.
