My transmission keeps losing its prime and the my trans guy says the torque converter anti drain back valve is probably bad. I looked in my manual and it doesn't have the part number or a picture. It just explains it as a valve that threads into the engine mounted transmission cooler and it is not servicable. I went to the dealer to get the part but all they list are the 3 lines and none of them say anything about a check valve. I talked with a couple of the techs and they pointed out the line they thought was right so I ordered it. I'm still not sure that the dealer is ordering the right part. I'm hoping someone on her might know the part number. If anyone knows and doesn't mind posting the P/N that would be great.

TIA
