Tranny fluid - 6G Celicas Forums

Topic #32058 4 posts Started by marcusk
What weight fluid should i use when i change my manual tranny fluid. I know everyone recommends Pennzoil synchromesh, but i cant find that here, nor can i find redline. So what weight should i use, or what does the owners manual recommend (i dont have one).
I'm pretty sure it's 80w.

I use atf in my manual tranny. The only difference is that ATF is lighter weight... so it shifts really smoothly... wont hurt anything.

I used 80w in my car and it shifted really horribly, really mushy feeling. I just switched to 75w90 the other day and I could shift through every gear with my pinky it's sooo smooth.
