Can't solve solenoid error code
My car 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 Y38y2 solenoid. Pulled again and replaced the Y38y2 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 Cread VIII reader so cdes have been cleared each time.

For people interested on a solution, you have to locate a used valve body with a Continental plate. And then you have to use several different methods that include MB online access for at least one of them.
I located an individual locally here in Los Angeles that programmed the plate first then updated the whole thing online. The valve body and plate came from a 2018
E350 from Ebay. Works great but it's the only way. You may only get the plate but it was the same 399 with the valve body.
If you do your own install replace all bolts, aluminum, and my valve body came with solenoids so great deal.
