Need help identifying a part
I had a tcm no communication problem and I bought a new conductor plate and nothing changed so I traced the can wires of the transmission harness to this little thingy in white. When I wiggle it all is well and my scanner reads the tcm. I didn't see a part number on it maybe one of you guys may know what it is

Because there are twisted pair wires going in to it, it's likely a CANbus distribution block.

In MB world this might be called the "CAN Distribution Block", "Distribution Block" or "Potential Distributor"

Is there an MB part # embossed in the plastic? It will likely have an 004 prefix.
