Seems this 'wet' connector problem of ATF causing 'Limp Mode' is getting traction.
Most late model trucks and cars have the TCM in the transmission ! So I do not see why the ATF in the connector from the plate to the loom would cause problems. After all, the shift solenoids all operate submerged in the ATF.
The problem I see most ...( especially the V8 ML.) is the TCM loom runs down next to the pre cat and the wire insulation melts and wires cross short. MB only installed a little metal shield on the front corner of the transmission ....not good enough.
On my own 430, I teased out the TCM loom wires and insulated them and made a heat shield .
30,000 miles and no more problems.
So, open up the TCM loom where it leaves the conductor plate connector and check for melted insulation.
