335i Auto question

snakedog · 04-07-2011, 03:18 PM

Im having a problem with my 335I auto. When im coming to a stop, say (7 to 0 mph) and ease off the brakes I get what can best be described as a thud/slap from the tranny. Its like its been braking the car up to the point of me releasing the footbrake and then releases. Its a noticable thud that makes you move in your seat. Its more so if the engine has been braking prior to stopping.
Any ideas? its been reset at BMW a few months back but made no difference.

Is it the sticky brake thing? Where the car still applies the brakes a little even after you let go of the pedal

I think there was a software update for this, which does not decouple the torque converter at stops.

Im convinced its the torque convertor, do you have any more info on the software update?

use a BT tool to reset the transmission adaption value.

How many miles on that auto trans? Have you ever changed out the fluid?

Its done 33k and its been reset 3 times by my local dealer, still no joy. Im hearing a lot about nic neutral idle control, or something like that. Seems like the 5 series had a similar issue?

Same thing happens to me! Whenever i slow down in normal driving, basically just creeping up to the redlight...i hear a "thud" or a stomping sound and i cannot dertermine what it is. My foot is applied on the brake and i hear the noise RIGHT when the car stops.

I just got my software update and whatnot but it started coming from it even before that too. I never did it until recent and im at around 43,000 miles right now...

mine does it too but it only seems to happen when the car is cold. Been back to the dealer a few times and always comes back the same way. They always say there is nothing wrong too.
