Syncro mesh / tranny fluid? - 2003-04 Mach 1 Registry Owners Club

Chad464v · 11-03-2011, 06:12 PM

Noticed my output shaft is leaking a little, no big deal but now that the fluid is a little low im planning on topping it off but ive heard a rumor that using GM syncromesh will help assist those fast shifts under high torque any thoughts?

Use this, wild bill's not-so-secret secret sauce.

Couldnt find the orignal but here is a post with the correct mixture, I'm putting almost 700tq down at the wheels on a stock trans with this mix, shifts great.

I have been using GM syncromesh for years and it's been like butter for me in every tremec it has ever been used in.

Tremec Manual and ProMotion told me to use GM Syncromesh in my T-56.

Seems what works for one car, doesn't work in the next.

In my own car i've tried a few different fluids, including the "secret sauce". Nothing has worked better than the GM synchromesh. It wasn't a huge difference right away, but over time it got better and better. You would never know its a tr3650 now!

GM part # 89021808

3.0 liters
