OK, sorry, 2003 E55 W211.

Finally some consistency. Car is now pushing out P2502 and P2503 codes on the trans module. Seems to now slip in 1st before jumping into 2nd them limp mode.

Does anyone know of the SDN (?) needs to be done to get it to work properly or perhaps I have a bad torque converter? Does not seem like the conductor plate is at fault here. I read I can have someone lock it out with the Star program to test the TC????????? Thanks
