    Im Dan from the UK and a bit stuck with the UZ swap. I have done one before, as 1st gen 1uzfe into a surf.

    As you probably know the old 1st gen LS is hard to get hold of (well over here anyway) and we are getting the vvti 1uzfe’s with the A650E gearbox which there seems no adaptor to go to the vf1a / rf1a transfer case.

    Knowing next to nothing about autoboxes and the black magic they work, I have a theory but not sure that it will work.

    What is it is, is bolting a A341E to the vvti uz engine and using the vvti ECU to run the A341E gearbox by splicing the relevant wires to give the signals for it to work. Below are the operating sequences for both boxes so would wire the A341E ‘L’, ‘2’ & ‘D’ to the A650E ‘2’, ‘3’ & ‘4’ as the solenoid sequence looks the same but the C,B & F are different but question is doe the solenoid sequence control them? I guess I would have to not wire 5th gear and low from the ECU. Also not sure about solenoids 3 & 4?

    I know I am sacrificing a good gear box for a not so good one but until someone makes an adaptor im pretty snookered.

    If im talking a load of rubbish im sorry to have wasted your time.

    Thanks Dan
