Hi,

I've just brought an 2002 Land Rover Discovery II with bad Automatic transmission!!

It doesn't move any direction with little move backwards.

the ZF4HP22EH gearbox cost 500usd here ... and I find a Range Rover P38 gearbox in the junk yard for about 150USD !! ... why not to try!

here is the complete trans:





different mount :



Different selector switch :

24



22



Removing the Transfer box:








The output shaft is 4cm shorter for the 22:







The Body of 24 is 1.5cm taller:

hp24 into disco 2 or defender v8

1: is there an easy way of drilling the hole in the end of the 4hp24 output shaft or doesnt it matter too much? do i take it to an engine shop or do I just give it a crack with the battery drill?
2: does the 4hp24 and lt230 fit back into a disco 2 ok or defender with its extra 15mm length or is there enough adjustment in the engine and gearbox mounts?

great pics and info!

Something to think about... will the Disco 2 XYZ switch mount onto the P38 auto box? I know for certain each XYZ switch is wired differently for each model... P38 4-wire connector vs. D2's 10-wire connector.
