Thread: Has anyone reco their ZF transmission

Jazzman recently pulled his Auto to pieces, He's on a trip at present, but he might be able to give you some advice.

Not a D2, but we had our previous D1's ZF auto reconditioned last year. It cost $4000.

Sent from my GT-P5210 using AULRO mobile app

Can rebuild a Road Ranger, Spicer, Mack, in my sleep, but never tried an Auto.
If I ever do, I will attain a workshop manual, and video/photograph every stage of dismantling, have everything set out in order on a clean bench, have all the parts at hand that need replacing and do it in one go.
It can't be too hard, can it?, Regards Frank.

I have seen kits from Ashcroft with the clutch packs and oil pump, bearings would be easy to source, seals and O rings come with the kit as well.

Have parts cleaner and compressor would be replacing torque converter and oil cooler too.

This vid shows fixing a reverse ZF 5HP19, shows some tricks , probably similar to other Zfs. Clean work area is a must with Autos.

I did find a schematic of the ZF Disco unit on the net in PDF, can't recall the URL now but it showed each part in order.

JPAT UK for parts. dont use genuine land rover drive plate . they are to soft & bend under load. mine ended up shaped like a saucer after 600klm towing a caravan. wrecked a good oil pump on mine.

Steve, your Disco is still "resting" peacefully out the front.

Had a look at the Jpat site does show an exploded view of the trans with the order of parts etc.

Stevo, I have a Workshop Manual for the ZF 4HP-22 sent to me from Florida, USA by a retired ZF mechanic.
I'm willing to post it to you if you are willing to look after it and post it back when you are finished with it, shows full exploded photos and diagrams and tools to use, let me know, Regards Frank.
