Tranny pan leakage

06 325i · 01-02-2011, 05:28 PM

The dealership told me the tranny pan is warped and that is the reason for the leak does anyone know what causes this? My e90 was bought brand new and has never been abused and this is the second time this problem has occured in the last 20k miles. Every time I go in my garage now I'm expecting to see a puddle of fluid (not the way i pictured owning a bmw). First fix was just the seal not the whole pan but i was still under warranty for that repair.

Don't know the cause but I do know that the pans are plastic. Plastic can warp.

Hopefully a better pan is in the works

I hate when trannys leak. No one likes a leaking tranny...

Probably would be a good time to change out the fluid when you change the pan. Check out the DIY section.
