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:




Now you have two options:

1) remove the whole internals to get the rear output shaft out and swap it with the 4hp22>

2) Cut the extra 4cm and drill a thread in the center.

I've go with option 2:

 

Good work! If..., I mean when you pull this off that will be quite the accomplishment!

 

true bush technology

 

you are right ... at least this will help someone on swapping ZF 4HP24 & 4HP22.

-----------------------------------

Will fix it to the car soon and see if the 15mm extra length will affect the rear drive shaft.

I'm planning to do 2" lift in the rear ... so it will take the 15mm easy.
