which redline synth tranny fluid?

[l.leung at juno.com]

Redline MTL or MT-90 are GL4 and are NOT 
appropriate for the diff. 

I forgot what Redline calls the GL5 
gear oil, but I believe that it is
a 75W-90 synthetic. Also Mobil 1 
synthetic Gear Oil (same weights)
is appropriate.

For the transmission you can use either MT-90 or MTL.  MT90 is a little
heavier and potentially provides a little better lubrication.  MTL is
suitable for colder climates or if you want to lighten the shift feel.

The rear diff is specified to use GL5 gear oil.  I am not sure if MT90
is the correct fill.
