Thread: ZF4HP22 do it yourself overhaul

Have bought this tool on eBay to make it easier to strip the clutch packs and am in process of making a clamp to mount the transmission onto a engine stand to make it easier to work on.

looking forward to following this as i will be in the same boat soon i expect.nearly 300000 ks

Stevo, I installed an Ashcroft rebuilt zf, having them install the 24 c1/c2 clutch and planetary gear set.

Dave reckoned at the time he would be happy to sell these 24 items to home rebuilders. Bit expensive, but there if you can't get a 24 box to scavenge from.

Ashcroft Transmissions

Lewy, when you've practiced on yours you can rebuild one of mine If you can do it yourself it does save an lot of money. Local Darwin entity wanted $6k for the whole job - is why I went Ashcroft in the end. My '94 Disco 1 auto box has over 590,000km on it.

realistically its probably\definatly beyond my bush skills,$so is $6000

Do you even need that puller?
You stirred me to watch [ame]https://youtu.be/JGbsgpp2YJQ[/ame] and part 2. It actually makes the inside a bit less scary.
There is also a 2 hour video of a honda auto rebuild.
My fear is paying out, doing all the work and *still* not having a working box. I don't have the kind of workspace to cleany tear down and rebuild.
Does that pack have all the o rings throughout the box?

I asked Ashcrofts about something similar and he said he had a few NEW 24's,,
I am resigned to my needing one at some stage--

maybe we should do a group buy

Nope it is not a puller, it is for compressing the springs on the clutch pack you could make one up but as time is a factor for me and it was a good price, on one of the BMW sites there is a video of some one doing the ZF4HP22EH valve bank and forward clutch pack.
