Range Rover Sport L320 Auto ZF Gearbox Fault Reading / Coding / Strip down ( how not to swap TCU ).

So we take a look at our new project car to see if we can work out how to get the replacement gearbox talking to the car. There are 2 ways to do this - one is via software to recode the gearbox... the second method is to swap over the computer from the original gearbox to the replacement one. In this video we strip down the gearbox / remove the solenoid valve pack / mechatronic pack and dig out the ECU... turns out the ECU cannot be removed but we should have replaced the whole electrical pack !
