Question about Chevrolet 1500
DTC P0751 - 1-2 Shift Valve Performance code. You could possibly have a valve stuck in the valve body or an internal problem.
1. Clear the code and then monitor scanner data for shift solenoids and verify the command for all 4 gears takes place.
2. If command is OK, then remove the pan and the two solenoids and air check the solenoids while turning them off and on to make sure they are hydraulically functioning.
3. If the solenoids are OK then there is an internal failure inside the transmission.
