Works - did it this am... parking lot speeds are now much smoother as are the transitions in the lower gears.

Same experience. I was updated to Progman 25 a few weeks ago and instantly felt a difference. Like you, I thought it was the update that solved the problem. Other posts related to Progman 25 indicated that improved transmission/gear shifts would result. I guess that the improved performance was not directly attributable to Progman 25, but only a side-effect (and a temporary one at that). Unfortunately, it seems that this new "trick" will need to become a regular and recurring part of the maintenance process. Here's a second vote for the demise of adaptive transmissions!!!!

I have tried this - and thought it made a difference.
Now, I'm not sure what to think.
I recently bought a copy of the E60 service manual from Bentley Publishers. It has a good section describing the function and features of each type of transmission available. In the Automatic Transmission details, it describes a feature referred to as: Adaptive Transmission Control (AGS) According to this, there are 2 maps for each position of the gear shifter (D or M/S) These maps are XE - extreme economy and E - economy and S - Sport and XS - extreme sport. AGS uses these maps to adapt to different driving styles based on several criteria: kick fast (how rapidly you press the gas pedal) Cornering aggressiveness, and braking aggressiveness.
All of this seems to align with what I presumed about the transmission - that it could adapt to my individual driving style - OVER TIME.
The last bit of info - puts that theory in question.
The last sentence states clearly that Driver Adaptation is RESTARTED each time the vehicle pulls away from a standstill.
Has anyone else ever heard this described in this manner elsewhere? Bentley is a respected publisher for such material... but would still like to have some corroborating information on this.
Thoughts?
