Thread: Need to know TD5 Auto to 300TDi bellhousing??

From what I know of the 4HP22, the Tdi bell housing should bolt up no problem, not sure if the flex plates are different though.

Also, the Td5 box will be an EH variant, so you'll need something like an Ashcroft compushift to make it work.

The Ashcroft Compushift is designed to work with an engine like the TD5, with all the electronic gizmos, like a TPS which the 300TDi doen't have. So are all the TD5 autos electronically controlled, Regards Frank.

TD5 ZF has an ECU so yes you will need a compushift.

Trouble with that is Ashcroft want 795 British Quid for one, could buy a complete 300TDi auto and T/C for less than that here, no way round it??, Regards Frank.

Would the internals, TD5 ZF, other than the electronics be the same as the 300TDi box internals, clutch packs, etc., Regards Frank.

I seriously doubt there'd be a lot in common, the 300tdi would have a hydraulic valve body, the td5 would have a set of solenoids. You'd be better off finding an old V8 D1 trans which should be more similar.

Bee utey, I just found my ZF-4HP-22 workshop manual and it covers both the standard and the EH box, seems, aside from the solenoids and wiring it is only the valve bodies that are different, the mechanical side looks to be the same as they only show the different valve bodies in a supplement at the back of the manual. I was thinking it might be feasible to swap the standard valve bodies over to the electronic box, any thoughts, regards Frank.
