Hello!!

Yes... I've search every ware ...

The car with bad trans is 2002 discovery (MENA) with ZF4HP22EH ..

I'm replacing it with ZF4HP24 from P38 ( with a Borg Warner transfer box. with speed ratio reducing gearbox) can't tell the model or any info since its in the junkyard alone without engine

Some say it will work if the 4HP24 is from P38 by just swapping the extension housing and rear shaft (not sure about the shaft) ..

others say it will not work since the internal wiring is totally different!

It will work with me with no problems ?

I need to buy it since its about 250USD instead of the D2 trans (1000$)

any advice please!!

 

Ok, If I replace the Borg Warner transfer box along with extension housing .. with LT230SE along with transmission extension housing to be fit into Discovery ... it will work?

 

I really don't think it will work, but I have never tried.

I think that putting the p38 trans and Borg Warner is the worst idea. If anything only try the trans, but I still don't think it will work.

I know that the flywheel/flex plate on a D2 is slightly different than P38(one sticks out further), so you will have problems mating the torque converter to the motor.

Where are you located? A D2 trans is the same price or cheaper in the US.

 

Sorry, just saw Saudi Arabia. Good luck

 

Hi!

I've already buy the P38 4HP24 without torque converter ... will post some pictures soon.

first thing ... the gear position switch need to be swap

 

The torque converter between 4HP22 and 4HP24 are different sizes, so you'll need to source the correct converter if you were planning on relying on the 4HP22 torque converter.

Also, the 4HP24 is slightly longer than the 4HP22, so you'll need the transmission and transfer case mounts from a 4HP24/ 4.6L equipped Discovery II to complete this fitment.

 

RacerX- I have used a 4.0 motor on an HP24 D2 trans, but never swapped in an HP22 trans on an HP24 equipped vehicle(vice/versa)... But, I know a local guy that "claims" an HP22 and HP24 (D2) can be interchanged without regard to the mounting points. He says his 2003 has an HP22 in it that he installed without issue. Have you done the swap? I'm curious. I have never laid the 2 side by side, but the next 24 I pull I am going to.

 

I've always been told that the 4HP24 was a few mm longer to accommodate for a slightly longer tail housing, but in reading into it some more, apparently there was an early and a later version of this transmission, and apparently the later version is the same length as the 4HP22.

Possibly.

I have no idea what denotes an early vs. a late 4HP24, but if the OP finds that the tail end between the two are different, swapping one from the other might be the way forward.

 

Unfortunately I started to hijack his thread.

He is attempting to put a P38 trans into his D2,and they are very different, but also have the HP24/22 numbers associated with them.

I do realize that the D2 HP24 is longer than the HP22, but was told that the length is negligible when it comes to swapping the 2 back and forth.

 

From what I've read .. there are three torque converter types , and you could interchange any with regard of input shaft diameter and flex plate.... my plane is to re-use the 4HP22 one.

for the extra length its 15mm only ... And I think if I re-use the rear extension from the 4HP22 (~10cm) it will solve the issue for the length and mounting .
