Posted by JustAnswer at customer's request) Hello. I would like to request the following Expert Service(s) from you: Live Phone Call. Let me know if you need more information, or send me the service offer(s) so we can proceed.

Hi there, I am Cam.

This code is for the 2-3 shift solenoid as a system. To have this code suggests that you have either a wiring issue between the Powertrain Control Module (PCM) and the transmission, bad connection in that wiring, bad wiring inside the transmission, a bad shift solenoid or there is the odd chance it’s a bad PCM.

I will post the phone call service request now.

Expert:  GM Tech (Cam) replied 1 year ago.

I highly doubt you will need to replace the transmission, I would suspect the odds are high that you need a new shift solenoid.

Expert:  GM Tech (Cam) replied 1 year ago.

The down side is that the solenoid is behind the drivers side housing and the transmission will need to be removed to change that part out.

Labour will be around 7 hours for this, and parts maybe 100$. This is not something you need a dealer for, rather a reputable transmission shop would likely be cheaper and just as capable of doing this repair.

This is a technical diagram of the solenoid and its location in the control valve body behind the end cover on the transmission.
