I am wondering about trans fluids. I run Redline Synthetic Fluids in my Nissan Sentra SE-R (auto cross/track car) and 99 Mitsubishi Eclipse GS-T (Summer Daily Driver) but I have had my audi for over a year now and have had all the fluids changed by my independent mechanic (Redline automotive Richland Washington) but I still like useig Redline Synthetics in my cars I love the stuff as it makes the shiftig action allot smoother. My ? is dose anybody know what redline fluid to run in the trans and rear differential? I like the light duty shckproof in my sentra and would like the extra protection in my audi as I would like to go and do a rally cross in the car and want to have the best protection for the gears and such when I do.

 

ye, its fine, if you serious in rally, then chage fluids every 500 miles, evrywhere.

 

I am not rally rallying the car. I am just going to attend a rally cross (like autocross) on a closed airfield in spokane washington. It is going to be a snow and mud covered course, about 2-4 min long.

 

Sjm autotechnik had some info on his website about tranny and diff fluids

 

Thanks I checked it out. I will run redline MT90 in the trans and there 75/90 in the rear diff. thanks for the info.
