If you look at the adaptation tables that you posted you will see the only figure at -180 is the 5-4 shift table. That should not keep the trans in limp mode, BUT the code (2) for the solenoid will. You need to replace that solenoid 1st. MB number 140-277-05-35 OR 240-270-01-89 with a list of $27.50.
