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

[Driven]

Sorry to bring this thread back from the dead but I just got my 4.8is back from the dealer today. They reprogrammed and updated all of the software. So far I am still having the same issues as described in the SIB. I drove right back and took the SA around the block to show him and he reluctantly agreed with me. So I will be taking it back in next week for further diagnosis. Will follow up with the findings...

My guess is an internal problem with the transmission, possibly the torque converter going bad.

Not sure if torque converter is going bad in your case,but from majority of the forum members who experienced lurching including myself (not as severe as some stated) it is internal design and operation of this particular ZF transmission and its software. Try to adapt your driving style especially during start/stop intervals. Please, keep us posted!

Cheers

Well part of it is the torque converter. Getting on the freeway a couple months ago I got a really bad slipping between a gear change accompanied with a bad whining noise. I continued to hear that for a while and now it has gone away and is non existent. All those signs pointed my though towards the torque converter.

The lurch is a totally different issue and is transmission related. I am very frustrated cause I have driven a 2007 Range Rover. Bear with me here, I know is not the exact same transmission but it has one from the era of when BMW owned Land Rover and it is the smoothest ever and no lurch stopping.

I expressed my dissatisfaction with my SA and I am going back next week, so we will see what they come up with this time. I will keep everyone posted as I find out myself.

I have the same issue - a shudder when the car is brought to a stop. My X5 is a MY06 3.0d, and I had the transmission adaptations reset with the software update. The problem seemed to had gone for a while but it is there intermittently.
Noit happy with the outcome. I am wondering whether to write to BMW Australia and state the case for a new transmission given that the car has done only 60k km in the upcoming five years of ownership.
