The trans apparently has 5000km on it since new so it should be fine. With the trans cooler I was just going to install a p38 unit, apparently they're better?

Haven't had much to do with or heard about the p38 coolers? maybe someone else can enlighten us??? as far as the medium TC goes, you'll have to compare overall and seated heights with the old one using straight edges and rulers! and unless you've found out about the v8 flex plate fitting the crank, you'll also need to make up a drive plate and i suspect machine down the centre hub as i did.... i'm only guessing though as i don't have a medium tc here to look at.

Are you saying the v8/td5 auto is the same, I thought i heard there is some differences at the back of the auto/housing somewhere? or something being longer on the v8 auto

They should be the same at the rear as it's an interface between the auto and transfer case.

The 24 is longer in the pump section (10mm?) but the rest should be same same

How is the auto conversion going? I killed the auto in my TD5 a few months ago and I am looking for an upgrade.

I'd like to know too. A tutorial would be awesome as well.......

I have bitten the bullet and got myself a recondition 4HP24 to put in my TD5 Ute.

For anyone that is interested in this conversion I have found a company in Melbourne that will make a flex plate to suit the Td5 to 4HP24 conversion and as result it will become an off the shelf item.
So if anyone else wants to do this now or soon PM me as it will help bring the initial cost of the plate down.

Just a FYI. I asked Dave Ashcroft about this a couple years ago:

I have the opportunity to purchase a low mileage ZF4HP24 out of a P38 Range Rover V8. I appreciate they are different, but I was wondering if I could make it fit without too much drama. Are you able to offer any insights, or point me towards someone or some website who can? The 4HP24 has the serial 0175667,and model number 1043 030 061.

It's not possible to convert the 061 to fit the td5 box, too many differences in the front, rear and valve body, even if you found a 4.0 p38 4hp22 this would be closer but it would still need a full strip to change the output shaft

Regards

The guy who started this thread has done it. Also a few others in the uk.

Like I said, just a FYI. I wasn't saying the OP was wrong, I was merely putting that up to show that Dave says that particular trans (1043 030 061) was no good, and Dave Ashcroft is someone I listen to when transmissions are concerned.

Hi all.
I have an 04 td5 with lots of mods one of which is 4hp24 upgrade with 2400 stall speed converter etc.. it's going really well but I've had an issue since conversion and I can't figure it out...
Intermittent m s fault.
Is there a difference in the xyz switches between the 22 and 24? I'm using the original 22 switch.
The 22 switch needed a mounting hole enlarged a bit to fit and I can only use one mounting bolt.
I've tried another switch. Same fault.
New battery. Cleaned earth etc. No change.
It's not consistent fault. Seems worse when towing or when my wife drives!
I'm getting fed up with driving everywhere with my nanocom connected.
If I need a different xyz switch ill need the pin outs and splice the plugs I guess??
Any help appreciated!
Matt
