What conductor plate are you talking about and what is the solenoid activating?

He's probably talking about the transmission conductor plate. How about sending it in for repair?

I thought you could only purchase new as one unit. Try a junkyard.

I had a fault code of "the internal test of Y3/8n4 has failed", and after swapping out solenoids, I replaced with a reman'd valve body/conductor plate assembly from the dealer.
The repair services listed above could not repair conductor plates with that fault code.

The conductor plate is all one piece with the "solenoid plate". they are one in the same. Dealer only. Will need programmed, will need programming and coding from the other module if you don't replace it with a new valve body.
