getrag top cover question
 
ok so i changed out my top cover the other day when my old one crapped out. when i took my old one off, there was no gasket between the top cover and the housing, and it never leaked with the 90w that was in there. but now that i have a synthetic oil in there its leaking.

does anyone know if there is supposed to be a gasket inbetween the two or not?

i used rtv to reseal mine when i had the tranny out for the clutch. no leaks so far

do you know if its supposed to use it normally? or did you just do it for extra protection

Would you rely on a pull-out method or wrap it?:humm:
The extra protection is worth the headache that comes from not using it.:scare2:
ha ha ha

thats funny:choochoo:

i just wanted to know if they normally use one because if they dont and mine leaks and no one elses does must have another problem somewhere.

a rebuild kit comes witha gasket for the top cover and i assume they had one from the factory but i just use rtv and mine never leak.

Early getrags used no gasket...

Later there was a TSB about leaks (amazing... no gasket and now we have leaks), so later Getrags got a gasket as well as some older ones had gaskets installed...

the gasket acts as a shim and a seal it holds the shift forks up off the collars to prevent premature where and also seals the top of the case
