Hi, I’m Ron and I’ll be helping you today.

Before we get started though,Please understand that I don't know your skill level or tools you have to assist us. Also understand that I can't see,smell, hear or touch the vehicle either, so your patience is appreciated.

My goal is to make you happy and get a great rating in return for my time.Sometimes I have to give you bad news that I know you didn’t want to hear, so please don’t shoot the messenger.

If the power feed is good, then check your grounds, also check them at pins 4 and 5 at the computer connector. Use a scan tool in bidirectional mode to operate the shift solenoids to.

Thanks, Ron

Identafix says that this a coomn problem and the wire harness needs replaced or repaired.based on the wire diagram. there is a connection where the solenoids connect to a common wire and go to the battery bax. The pcm relay is in the box. Which relay is it/
