DIY: Transmission Oil Change

spearfish25 · 09-22-2010, 09:01 AM

Sure thing. Looking at the motive pump again, I'm tempted to just make my own adapter and use my brake bleeder Motive pump to do the diff oil. Since it already includes a fitting to change the different caps you use, it should be easy to make a tube that screws on and has a 90deg hollow metal end to go in the diff.

I installed straight MT-90 in the transmission but can't say I would recommend that overall. The transmission felt great on the track but is notchy on the street especially when cold, the oil is too viscous when below 200F. The new MT-85 looks to be a better recipe for our transmission.

I am currently shipping back the 90 to Z1, and in a few weeks when it arrives

they will ship out the 85.

If you don't mind the wait, that's fine. If you want it done sooner, just mix them. Very simple to do.

It's not gold, it's brass, I'm guessing from the syncro's. A small amount during break in is ok but if it continues you have a problem. How many miles?

Not to worry- that's not too much glitter. The other thing to watch for is any large chunks of brass or steel in the shavings. It's normal for there to be some syncro wear, but anything that looks like a small mass should be examined more closely. Whenever I change the tranny oil in my road race T2 Z, I look very carefully at the "glitter" to make sure no major damage is showing up.
