TranNY Trouble
My car (2008 ML350) went into limp mode and had code 0748 Y38y1 fault. Pulled the pan and valve body and replaced the Y38y1 solenoid. Put back together, new filter and oil. Ran ok for a week then limp mode again with same code 0748 but now Y38y1 solenoid. Pulled again and replaced the Y38y1 solenoid, new filter and oil. Back again ran great 2 weeks then limp mode again with same 0748 code and same solenoid Y38y2. Anyone have an idea what is wrong? Should I replace all solenoids? Could the conductor plate be the fault. Time for a pro? I have a Cream VIII reader so cdes have been cleared each time

Star Diagnostic must be used.
