Sorry I did not mention the price. The price they quoted me was $400 which includes gasket, filter and full flush with genuine ZF fluid. I know ZF don't only do BMW.. All I said was they deal specialize in BMW/zf and use genuine ZF fluid.. I know how to service a car lol.. I've probably taken out other motors and fiddled and fixed and modified more times than I can remember. Like I said there's such a dilemma when it comes to servicing transmissions and I don't want to fork out 3-5k if anything did happen to the transmission.

The reason why I wanted these guys to perform the service is..if anything were to happen its on them.. Not me. You can use your nulon fluid lol that's your transmission not mine. If you don't believe the $400 quote... I'll screenshot it from grant at A&B automatics.
