I'm just about to put my 4th transmission back into my truck (a 1940 Chevrolet) Trans was initially out of an 84 chev 3/4 ton diesel, but has is fresh, just back from the transmission shop with a fair bit of performance type additions. It is a 700R4, and will be driven hard (mostly street use, with occasional 1/4 mile drag race) behind a 427ci Big block chev. Looking for recommendations for what oil to use in the 700R4. Hoping to get a lot more life out of this trans than the last go around (3000 miles)...
Thanks!
Matt
