Transmission Oil & Rear Differential Oil

[gotboost]

Iam going to be ordering Red Line MT-90 for my transmission, just want to know how many quarts I should get? And what should I get for my rear diff.... Red Line 75W90 or 75W90NS and how many quarts? And also were is the cheapest place to get the drain bit?

Thanks

just use same stuff for rear diff. You can add a little redline shock to the MT90 if you'd like, or just use the MT90 or MTL. germanautoparts.com for 2 in 1 trans tool. I think I used 5 quarts total (trans, diff)

Get Motul Gear 300!




This way the same oil goes in gearbox and rear diff!

Keeps life simple!

I also bought Gear 300, though I have not yet put in in. 5 quarts total, three for the trans, two for the rear diff. I use it in my supermoto trans as well with superb results (and that's a race motor).

so mt-90 will work in both.....

Yes MT90 is fine for both like I said. I personally use Motul 300. It's a tad easier on shifting smoothness...

you use the gear 300 all around? and the others guy too.

anyone here compare this to amsoil in the tranny/reardiff.

I have friends who have used the amsoil products and was going to go that route. I have not heard anything one way or the other on the gear 300 in audis. I know the subbie guys LOVE it!!

I am going to change mine soon. I can use either one, just wanted to see if one was better than the other one.

Where is the best place for the Motul 300?
