Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

What fill port is this on a ZF tipt gearbox? It's the allen socket plug to the left of the CV flange, passenger side.

POST 2Original post

That's the differential oil filler. It should take gear oil not ATF. I don't have the gear oil spec for the ZF tip.

POST 4 / ORIGINAL POSTEROriginal post

And this is the Factory-Fill-Port for the ZF fluid. It pops off and you put a small funnel into the hole to pour in the amount you need. This has restored my faith in German engineering because I absolutely know for sure the factory does not fill the transmission with the car on the lift, engine running at temperature. There are two similar ports on the Mercedes gearboxes for Porsche as well. When the engine is out, this is where you fill it. Or, overfill it and drain the excess out afterwards.

This is a source reference. Confirm exact model applicability in the original material.
