I decided to go with the Redline fluids for the tranny and transfer case.

I mixed the MTL and MT-90 50/50. So far so good. (2 days, 40 miles)

You can get redline oil at many performance shops. I got mine at Jegs (local) but you could also get it through their catalog.. $7.99/qt. with free shipping.

Beware though, others have expressed problems with the MT-90 (ChuckH?)
