    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:crazy:

    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.
