I have been told that the 700R4 trans to use is the 87 and up.I have a 93 jimmy that have a 4.3 in it and a new trans, I was told that it has to be a 700R4. If so will it work in my camaro with some up grades? What is some of the best mods to to do to make it strong enough to run in my 77 camaro with about 385hp.
