335i Steptronic AT: Smelling ATF under heavy load shifts

hasta la pasta 27 · 04-22-2014, 11:02 AM

So my AT os shifting fine....minus that i am getting a smell of ATF under loaded shifts. regular driving, i do not smell it but i step on it and shift...the smell is apparent. Im guessing it could be the mechatronic sleeve. i did my transmission fluid and pan/gasket about 15k miles ago. My question is, has anyone had this and is it JUST the mechanic sleeve causing this or is there something else i should be looking at?

Thanks guys

I would first check if there is a leak to begin with, Is there any red fluid dripping when you have your car parked? If you did not change the sleeve then most likely that my be the cause, but first check if a leak is present before throwing money at it.
