Brand new clutch got ruined because oil leaked onto it from tranny front seal. I know cuz the gear oil i use is purple. While im at it i will also replace the rear main seal. Do any of you fellas know if the 2nd gen 3sgte rear main and front tranny seal are the same as the 4th gen 3sgte? If not do you guys know where i can order one? Primemr2 is usually my main place to go but i cant find it there. Thanks guys!

The part number for the rear main seal on the Gen4 is 90311-89001. This cross checks to all of the 4th gen and 5th gen Celicas (ST16*, AT180, ST18*) as well as the MR2 (SW20, SW21).

Not sure what seal for the transmission you're looking for though. Is this on an alltrac? I see there is a transmission seal (P/N 90311-50010) but it's not in the bellhousing.

Thanks for the part number Tim. I probably have my vocabulary for the seal wrong which is why I'm having a hard time finding it. It's the seal that is around the input driveshaft. Does anybody know the correct word for this part?

I'm not seeing a gasket around the input shaft for the St185 model for the blowout I'm looking at. You can ask Lithia and they may be able to help better :-\

Oops sorry. It's a s53 tranny mated to a 4th gen 3sgte
