I have 2 good, 700R4 transmissions sitting in my garage. 1 trans is out of a Z28 w/50,000 miles and the other I am told, is out of a full size van. Which one should I install in my fullsize GMC 3/4 ton pickup that has a 300hp 350 crate motor?
I tow a car trailer at times, but I need the OD when I
I'm not towing.
Is there anyway to tell which one has more clutches in it , just by looking at the numbers on the case?
