"The Lurch" does any of the tranny updates fix it?

It has to be a programming issue if switching to DS solves the issue for most people, right?

I would think so. The SIB describes the exact problems I have. However the dealer want $180 to reprogram the transmission with new software. They claim "It has to be plugged into the computer and programming takes about 4 hours."

Anyone able to shed some light on if new software will actually fix the problem?

It must be programming..it makes sense... why does it occur only in D moded and not in S mode.

I believe (and i am not an expert) the lurch is happening because it is shifting down very late, when the speed is very slow, so the downshift is causing the car to lurch....

In sports mode, it is downshifting at earlier and at higher speed so the transition is smoother and the downshift is actually causing the car to rev higher and slow the car down.

Is there anyway maybe if the downshift in D mode could be programmed to occur earlier or in the same manner as in S mode?

Maybe we are expected to drive in traffic and town in S mode ?

Is there anyone out there who has the lurch in S mode ?

sorry "sunny5280" i did not mean to imply that the fault is not real.

what i meant was that for me, i have managed , for the most part get around it by modifying MY driving style.

i believe as has been stated that it is a programming issue, and BMW should step up and address it.

and im seriously hoping its not an indication of a failing transmission
