Yes it was my E90 325xi with a ZF Transmission, NOT GM Transmission. Exhaust bracket covers the gap to access the fill hole on the top of the ZF Transmission...
I used the ZF Fluid for the refill, they say it runs cooler for better mpg's...
Wow, OK, well wth do I know! My bad! I guess the e90 325xi has a different ZF tranny and different exhaust routing than the e90 330xi I have.
I also used ZF fluid, Lifeguard6.
