Anyone know of a transmission specialist in Sydney who can put the 4hp24 clutch packs in and do a service/rebuild without ballsing it up? Was going to send it to ZF, haven't spoken to them yet.

Hey Mate;

AFAIK , ZF only carry out a Standard Rebuild , another words they replace worn parts with OME parts. not sure if they put in heavy duty clutch pack out of a 4hp24 , assuming your existing one is 4hp22.

Yep, existing is 4HP22.

So we need a guru then!

I know a guy in Canberra.

Just out of interest.... who do you recommend in Canberra? My ZF went a bit erratic and one guy told me i needed to spend around $5k fixing it. However, after a service it has been fine so far for around another 30 to 40 thousand k's. But would rather take it to someone who knows for next service.

Hey Ed

did you ever post a list of gearbox mods?

or did you have to sign a non-disclosure?

When I had mine packed with all of the 4HP24 parts I had AMV do it and they sent it off somewhere, but just about everybody said that A&B transmissions (???) in Melbourne to do it. Apparently they are the guru's outside of ZF in Germany and ZF sends people there for training on the ZF transmissions.

I don't know half of the work done.
I do know that the new clutch packs have extra meat on them and there are more plates than in a standard box. Valve sprigs are heavier to.
It now has a custom oil pickup in the sump.
Since it was done at mates rates it was a case of only listing some of the work on the bill.
I did get a load of bits back for my amusement.
