Hi can anyone help me i am doing a td42t conversion and i want it to remain Auto, now i have still in the car the td42e auto which is in very good order. I also have a Sahara auto with no transfer case so i could use mine, i know is 24volt but this will be changed. Ok so are the internals the same ie gearing etc or should i just put it in as it was behind a turbo motor originally. i already have the flex plates bell housing etc, i just dont want to waste time if its the same box...
