My "Lifetime" tranny fluid at 115K feels pretty worn. Its getting notchy, feels like it sticks a bit, and I really have to baby it when its cold. If your not doing a soft 2nd start when cold, you really have to jump from 1st to 2nd gear(as you all know), and the ol girl doesn't like it one bit. I'm in a pretty cold region in northern Utah. Park City on weekends during ski season.

For everyone, I'm interested on opinions/experiences from using an aftermarket fluid vs oem fluid. On my e36 I used mobile one synthetic mixed with lucas synthetic additive and loved it, but on a more modern manual tranny that I think calls for something closer to ATF fluid and not typical MT fluid, I'm a little in the woods.

Not to hijack the thread, I'm just interested on what other people are running in their manual X. Glad to be part of this crew.

What I used:

Manual Trans - Redline MTL (70w-80 weight, OEM is 75w-80 BMW MTF-LT2)

Front/Rear Diff - Redline 75w-90 gear oil

Transfer Case - Redline D4 ATF

Picked her up today and it wasn't a HUGE difference shifting, but definitely shifted nice, I think it helped. I'm a big fan of keeping up on fluids!

Glad you're part of the 3-pedal crew and glad this thread is beneficial!
