Re: Transmission fluid
I assume it's an Allison M20 - it doesn't use "Transmission" fluid, at least in this application. Use the same oil you use in your 8V71s. Should be straight 40Wt meeting CF2 Spec.

If you want a specific brand, I use Exxon XD-40 in mains, trans, and genny.

Re: Transmission fluid
Straight 40 in the gears - same as in the engines.
DO NOT run multigrade in the gears.http://www.denninger.net - Home page with blog links and more
