Transmission issue?!?

E90Graphite07 · 02-01-2012, 08:21 AM

About a year ago, brought in my E90 to the dealer regarding a transmission leak. They ended up replacing the Mechatronic sleeve. Now, the vehicle has left a small residue on the same area as last time, and I'm also noticing the vehicle shifting a bit weird. From a cold start, as you coast from first -> second (6AT), the engine idle revs up another 200-400rpms between shifting. It goes bout 200rpms when shifting from second to third gear. Any thoughts?

You are probably low on fluid. Run, don't walk, back to the dealer and have them check it out.

Not so sure it is a level issue. There are a lot of possibilities but all will involve the dealer figuring out what is wrong. Small residue and no fluid on the floor makes it fairly unlikely it is a fluid issue and if it was from the last transmission service I think it would have been an issue long ago. There is a series of solenoids that actually initiate the shifting so it could be one of them. Best of luck
