Thread: simple differential question

All HD diffs are 3.29 in a 4T65 trans. Make sure you put the sun gear in the correct way and you'll be good.

ATSG manual says to put a big screwdriver or wedge in there and give it a whack... it's all good as long as it's a fast hit to make the compression ring compress.
