I have a 98 4r70w will it work on a 01 with the 4r70w both are 4x4?? Anything different or mods that will have to be done??
Same engine? As long as the length didn't change, connectors are the same, and hole patterns match up, I see no reason why it wouldn't work. I've been wrong in the past though
It'll work fine. They didn't really mess with the transmissions until 09 when the new 6-speed came out. I would do a rebuild with upgraded valve body on the replacement before installation as well.
I though some of the wiring changed around '99. I could be wrong, but I think I remember reading that somewhere when I did an engine swap on mine. Something about the shape of some of the connectors on the harness. Edit: OOPS. Just realized how old the thread is.
