Q: How Long Until Adaptive-Transmission Locks In Driving Habits (After ECU Reset)?
So there are a ton of threads on "ECU Reset" and "Adaptive-Transmission Reset", but very few of them say how long it takes for the car to "lock in" or "remember" your driving habits (if it ever does). So far, in all the threads I've read, the following answers were given:
40 engine starts (remembering habits while the car is running)
40 acceleration/deceleration cycles (from 0 mph to 0 mph)
200 miles
300 miles
400 miles
NEVER (always is learning)
Does anyone have a DEFINITIVE ANSWER to this question? Since my last "Adaptive-Transmission Reset", I'm almost at 400 miles. Is that enough whereas my vehicle won't "remember"/"lock in" my habits anymore since it's "memory" is full? Or does the vehicle ALWAYS remember your latest driving habits, discarding the earliest one(s) to make room when it's needed (in which case, it's pointless to "train" the car by driving aggressively since eventually when you switch to a more relaxed driving style, your "Adaptive-Transmission Memory" will eventually remember your relaxed driving style and you'll have to do the "Adaptive-Transmission Reset" all over again to get the car "back" to where it's most responsive?
You know, it would be A LOT easier if Mercedes-Benz had a "maximum" option in STAR where the MB Technician could keep the "Adaptive-Transmission" as it is now, or switch it to "maximum" mode where the car will pre-populate its memory with the most aggressive driving instructions and reject any new driving habits from the driver (essentially turning off the "adaptive" part of the transmission). That way MB owners who want to keep their cars that way won't have to drive crazy for 400 miles just to "train" their vehicles...

Have you gotten any answers regarding adaptive tranny times?
Thanks!

Great question! I actually think for this to be practical it needs to analyze the throttle usage in the immediate past. For example, if I am late for a meeting, I am going to drive a bit more aggressively than if I am out on a date, when I'm going to drive extra gently. If the car learned my throttle feedback when I am running around town late for meetings it is going to create an awkward driving experience when I want to take it easy and enjoy the ride. Maybe the throttle is fast enough to learn gentle driving AND more aggressive driving and can react to both scenarios based on how the throttle is used. I would not be surprised of the particulars of this algorithm is actually not public information because after all that's part of the secret sauce

DO NOT reset it if you don't have severe shifting problems. That's all I'm saying to this (nerves stop a running system). Just because one can do it doesn't mean one should actually do it.
If someone does want me to reset for whatever reason PM or email me. I'm def. cheaper than the stealerships.

Slow 0-60 on ML350 blutec adaptive transmission
Test drove a 2010 ML350 blutec on multiple days. It has paddle shifters. It was a dog 0-60 in 12 sec with both paddles and full auto. Salesman at dealership blames the adaptive tranny and says no codes come up. I own 3 other MB's but all older with 5 speeds. They never were dogs like this. This thing has 400 ft-lbs. and is rated at 8.0 sec 0-60. Could the adaptive tranny really do this?

Per my understanding shift adapt apply to normal driving and slowing down, while with kick down switch pressed, I would expect the program going to redline no matter what previous adaptation it had.
On 1998 my transmission would change the adaptation after 2 miles of mountain driving btw.
So if the car takes 50% more time to get to 60mph, I would seek serious engine issues.
Also I hear it more than once that "no codes" for salesmen is actually "no CEL" while scanner can find codes.

have it checked by an independent and tell them to be on the lookout with the tranny.
