- Press the gas pedal to the floor and hold for five seconds
- Turn the key to the "off" position (don't remove the key), then release the gas pedal
- Wait at least two minutes for reset
This supposedly resets the trans adaptive settings back to factory settings until your driving habits are re-learned.
I also erased the P0715 code with a generic OBDII reader.
So far we've been driving it daily 2+ weeks with no problems. Still, I ordered and am waiting for a mutliplexer to arrive so I can hook it up an also erase the transmission control module codes. My local Indy would do it for $90, but the mltiplexer was $105 (Dealtime.com) so I made the investment.

This would have been great info two weeks ago!
Update:
The indy that I took it to had no clue about MB tranny codes. He stuck by his claim that I still had a problem because the engine codes kept coming back. He would not admit that he didn't have the right equip and charged me for the diagnostics anyway.
Trailered the vehicle to the dealer. They read the codes, and reset them for 1 hour's labor ($115).
Car drives great now. I'll drive it for a week now to confirm the fix before releasing it to the wife.
Total outlay:
Conductor Plate...$180
MB ATF $15/liter x 4...$60
Filter, spacer, gasket, tax...$64
Indy mis-diagnosis...$65
MB code reset...$115
I'm OK with a $485 tranny fix, and even better if I can reset the tranny codes with the above procedure.
What I don't like is $15 per liter for ATF. Is there a lower-cost alternative?
Thanks for all your help guys. As usual, this forum make potential headaches fairly painless.
