Leaking Transmission Pan

Digitalism · 08-03-2015, 10:26 PM

My transmission pan was leaking, which is a common item that fails so I had the transmission pan replaced along with the mechatronic sealing ring.

After a few days I came back to a small puddle of tranny fluid. I took the car back to my mechanic who cleaned it up and re-tensioned the bolts. Again after a few days it leaked again, the shop has replaced it with a second brand new transmission pan.

It continues to leak even after a second pan is fitted, the leak has been isolated around a few bolts and these bolts have been replaced just to make sure they were not stretched. All bolts a torqued to the correct value.

Has anyone experienced this? Any solutions?

My mechanic is stumped. He even called mates at the BMW dealership, who haven't encountered this problem before.
