Had some tranny work done at an indie shop. His scanner/tools cannot reset the transmission adaptation values. Are other tools available to do this that I might find at another shop or is this something I need to take to the dealer? I have an OBDII scanner, might this be able to reset the values? Any other options? Thanks. '99 E300D (W210) 722.608 transmission

Don't think OBDII scanner will clear the codes. Afraid dealer is the only way or an indy shop with the right setup and software.

You can try to re-adapt the trans on your own!

Dis-connect the battery for a least an hour.

The drive the car very "SLOWLY" allowing the trans to shift each gear from 1st to 5th NEVER allowing the RPM to go above 1900 & then cost to a stop.!..Follow that procedure (1st to 5th) 4 times then allow the engine to idle for at least 10 minutes! That will adapt the transmission...

OF course you DO need a scanner to see if the adaptation is NEAR the maximun allowed & to erase codes in the TRANS computer...not ODB2 codes!

Adaptation only applies to the 722.6 (5 speed auto) and 722.9 (7 speed auto) electronically controlled transmissions.

Removing battery power will not reset the adaptation values. To reset adaptation values you need a fairly sophisticated scantool, one that can communicate with the transmission control module. Example, snap-on MT2500 with the S20 personality key, Snap on Modis or Snap-on Solus. Off-course the MB tools such as the HHT (Hand Held Tester) will do this as well, my experience is with the Snap-on tools.
Once tha daptation values are re-set, you need to follow a re-adaptation procedure. One of the menus on the Snap-on tool will show you all the readings you need to perform the procedure in one display window. The readings are :1-Engine Torque 2-Actual Gear 3-Desired Gear.
Below table shows the appropriate engine torque values for a '97 E420. Other models have different recommended torque values.

Upshift Frequency Torque in NM
1-2 4x 13-40
2-3 4x 25-50
3-4 3x 22-70
4-5 3x 0-110
Downshift
5-4 3x
4-3 3x

Do not exceed 1800rpm
Oil temperature '60C to 105C
AC Off
Idle for 10 minutes in P for storing

I too was going to suggest that removing the battery might not clear adaptations. I know a few months ago I installed a used controller into a car to evaluate a problem and without even driving the car the controller had adaptation values. I had the controller on a shelf for months prior.

Adaptive memory should only be reset when you install a different transmission; used/ rebuilt or a transmission control
Module. Why would you want to erase valuable collected diagnostic data, and data used to optimize the shifts and performance
Of the INSTALLED transmission, only to go thru a drive cycle to teach the transmission control module the same information that was
Just erased.


If a minor service was done, valve body changed, conductor plate, harness oil ring, just clear all module
Codes and drive the car.
