The auto is the same as the td5 disco auto box, though I'd 'guess' you'll need the td5 bellhousing.

I'm not sure on the td5, I only use the reverse light wire from my auto. Not fussed about the inhibitor, that's just a nanny.

if its out of a Disco1 then it will be a ZF4HP22 which doesnt have any electronics to worry about. If its out of a Disco2 then it will be the ZF4HP22EH which is the one which requires an ECU. You can get one from Ashcroft called the compushift for about a grand.

It's a discovery 2 gearbox. Think I am going to have a try with the discovery ecu first see if I can get it to control it.

if its not a manual box you wont get it to work without compushift, for one thing a def doenst have the pitch and yaw sensors that the box ecu looks for.

for non e box you will need to find a way to accelerator feed to box. alot revert to cable actuation just for the box.

note V8 TC is prob not ideal size for the td5. Cheers
