FWIW, Castrol Syntorq is the only MTF that GM and Chrysler authorize for use in the New Venture NV4500 transmission that is used in GM and Dodge trucks. I do know for a fact that the NV4500 uses some type of fiber synchro's. I won't swear to it, but I *think* that the fiber used is carbon fiber. so I doubt that Castrol Syntorq would have any deleterious effects on the synchro's.

NV4500HD Specs:

Manufactured by New Venture Gear

well that doesnt apply to us since we dont have CF synchros in ap2 transmissions. We have carbon coated brass.
