Next time my car is in the shop I'm having the rear and forward bushings replaced. I'll update if this solves the problem.

My 05 4.4i had similar transmission problems (100k miles):

• hard shift from 1st to 2nd when I accelerate slowly
• noticable gear change from 2nd to 1st as I come to a stop. Tends to push the car forward just as you are stopping
• very hard shift if you accelerate before coming to a complete stop.

To try and solve this I first did a change of ATF fluid using RedLine D6 (approx 5 quarts). After this all three problems were still there but were noticeably less. That was a good start, but I had hoped it would help even more.

The next thing I did was to "reset adaptation values" using the DIS V57 software. This is the page showing where I did this in the software.

This worked miracles and completely resolved the first two problems I had. After resetting the values, I was still able to make the 3rd problem reappear, but it was significantly better than before. There is another option on this page to "reset the control unit" in the transmission, but I am nervous about trying that. I am quite happy with how resetting the adaptation values has fixed most of my problems - this almost seems the same as rebooting your computer after it has been running for weeks. Everything works better as the computer resets a number of values and it seems to run more smoothly.

Whitecat - DIS V57 is part of a software package that you can use to read error codes, diagnose problems and alter software parameters on your BMW. I purchased one of the software packages from David Wragg in England and installed it on my laptop. I have used it several times to diagnose problems with my PDC (parking distance control), error lights for ABS/DSC and all my transmission problems.

It is really helpful software if you are trying fix things yourself.

Thanks for this ... I have found one on eBay

Whitecat - you will need the one that also has the cable that connects to your OBD II port under the dash. See here

Many here, including me, have you the following source: BMW USB OBD Diagnostic Cable Inpa Ediabas NCS Expert Dis V57 SSS V32 GT1 Progman | eBay

A reason to go this route is, if you have any install problems you will have help here. You will need a windows laptop. I dedicated a windows based laptop that had XP. Some versions of windows don't work or don't work as well. The DIS software takes a considerable amount of space so be sure you have the capacity. The software will work on an external drive.

bcredliner - thanks for this information. I purchased from David Wragg and he provided assistance to initially get the software working, but has not responded to any of my queries for any additional help.

Getting help through this forum is a great reason to go with your recommendation.
