Thread: ZF tranny oil?

Google is your friend. Google ZF approved oils or suchlike and you will see the approved oils for a 4HP22 on the ZF site.
I use Castrol Transmax Z full synthetic ( which is beyond dex3)with no problems and it is an approved oil.
Regards Philip A

We use only Dexron III, no issues.

Yesterday i googled ZF and Transmax Z and the concensus is Transmax Z is highly regarded for auto's and some manual boxes.

And its cheap to

I looked at it and put Dexron 3 in, far to dear for me

Yep, its pricey but if it means i get a few more thousand k's before a rebuild (god forbid) i guess its worth it. Mind you if i was working it hard on a regular basis i would just use the dex3 and change more often.

Yep, there is only really 3 ways to kill an auto prematurely

1. fluid impurities, moisture especially

2. heat, cooked fluid ****s them real quick

3. mechanical failure, very rare, but when your abusive like myself, you get to see some strange stuff


Top 2 are prevented from regular fluid changes

the 3rd, well as mentioned, get of the load pedal

So if the fluid stinks/ looks of color, its burnt, change it promptly

Last two destroyed ZF autos we had in here had been so hot the plastic breather tubes had melted!
