Transmissions are generally the same, the bell housing is a little smaller in the NA than the TT, but if you have the TT one, just swap the housing and it you will be just fine. Everything else is the virtually the same, the speed sensor is the same but the gearing is different that is on the sensor, very simple to swap out, either way it will work just fine. It will make your speedo off using the tt gear on a NA rear end, I think about 5-10 mph, about where mine is at.zswap0429 wrote:Also can i use the 5spd trans from the na on the tt?
