Thread: zf-4hp24 into D2 td5

The xyz switches the same. Try readjusting the position.

Ok so i can't add pics here...
Check my switches album. There are two pics.


First pic is an eBay listing for a p38 xyz switch ie from a 24 box.
Second pic is my switch.
Note the mounting holes are reversed. The slot and solid bit are reversed.

Not sure where to look for the pictures, nothing in your album.. the Part number for the D2 V8 (HP24) is the same for the TD5 (HP22)

Where did you torque converter plate made for the conversion?

So I spoke to Dave Ashcroft.
The 22 has a O stamped on the end of the sector shaft.
The 24 does not.
The d2 switch must be used. A p38 one will not work.
So I need to drop the sump on my box and change the selector shaft for an o stamped one.
The shafts are very similar but the angle of the flat is different. That's why I keep getting m s faults.

So big thanks to Dave and I know what I'm doing next weekend.

I used my original d2 td5 flex plate and a custom built 2400rpm stall speed converter.

Good to know!

Thanks for the info. About to start my conversion, wish me luck!

So after lots of work. Some success. I lowered the box enough to get the selector shaft changed for the o stamped one and now I have much less s m faults. Yay.
It still will fault if you change from r to d too quickly but hopefully that's manageable. I'll strip my spare switch and see if I can clean up the contacts. I might refit that one to see if I can get it 100% right.
Took it for a test drive towing the horse float. Much better but when I got back engine temp was 107º!!!
I might need to wire in another fan.

Good work. My boxes are put also just need some clean bench space to switch some bits. My hp24 has the 0 stamped selector so I should be good to go!!

4hp24 is in! The lager TC is noticeable and have have some strange shifting going on and cruse control no longer is working. Just wondering if i should get hold of an auto ecu from a v8 disco??
