Been running diaqueen for years with no problems. MT90 for trans and Wavetrac but obviously the trans fluid only sees the LSD and not the ring and pinion. Checking into see what everyone else uses for tcase fluid. My car sees only track day mileage and a few street miles for tuning or beer runs. As we all know the tcase holds less than 1qt of fluid, seems to me that would be a very easy quantity of fluid to overheat. I typically change tcase fluid every other track day.

I go with Diaqueen or redline 75w140. Whichever is more convenient for me to get when I go get it...lol. Same for rear diff.

I use TRE recommended oil. REDLINE 80W-140 GL-5 GEAR OIL. I change it once a year and add 1/2 a pint more than OEM recommendation.

Dang! Good read.



I use RL 75w140 in rear diff, Weir performance clutch plates are happiest with this stuff. Never thought about using in tcase.
