The Trans harness plug connection can be flaky and sensitive. If there is a crack, I'd replace that connector and see if that is the issue.

If you want to save money and if you need replace the conductor plate, get the factory "Kostal" made unit. Kostal is the OE manufacturer on plate and connector parts. Cheaper than getting it from Mercedes. "1161" and "1261" the common revisions out there. "12" is the newest.

Lastly, Make sure you torque the valve body in "inch pounds" I think it is 72 inch pounds.
