Transmission/TC Grease

[David70FJ40]

Getting ready to install the H55. Any recommendation on which 90 weight to use?

Recommend using GL4 over GL5. GL5 is VERY slick, which can become a problem, specifically with the brass cone synchros in your tranny. Shifts have the ability to be harder to make because the snychros can't grab the cone of the gear.

Any GL4 rated gear oil in the 75w-90 weight will work fine IMHO.
