David,

NEESDWINGS.com, a contributing vendor here, can provide you with a replacement Mercedes-Benz electronic connector. I just replaced mine when I drained the trans and replaced the trans filter. Here's their package price which includes this electrical connector. NeedsWings Performance Products. 7226 Transmission Service kit

I'd give Needswings a call to see if he'll sell you just the plug. It is out there on fleabay. https://www.ebay.com/itm/Mercedes-be...PlFF:rk:7:pf:0
