2002 ML500 Limp Home Mode

I have a 2002 ML500 and it goes into limp home mode after I turn it on and drive it for 8 minutes. When it goes into limp home mode a bunch of lights light up on the dash. It drives perfectly fine before it goes into limp home mode. If I pull aside, put it in park, and restart it, then I can continue just fine for another 8 minutes. I checked the 13 pin connector, but it’s dry. I have code P0720, P0600, and P0730. What might this be? The conductor plate has also already been replaced.

Look at highlighted codes on pages 12 & 13. It indicates that there is a problem in Trans. Control Module and codes must be read in that module.

Reading the codes in the Trans. Module will determine what speed sensor is at fault.

How do I read the codes in the transmission control module?

Since you posted codes in the ECM, I presumed you had a scanner. A code reader will not do.
