I just got done installing a complete solenoid kit including the wire harness and updated gov pressure solenoid I now have a code P0868 trans fluid pressure low. The truck operates as it should but starts in 2nd gear as if first no longer exists. I did remove the valve body to install the wire harness. I messed something up but I'm not sure what.

Starting out in second is usually the gov pres solenoid. Ya sounds like you pinched the harness or something else.

Thanks for the reply. I just dropped the pan for the third time in 2 days and put the original gov pressure block back in and all is fine now Bought the kit from electrical advantage and it came with a dnj components solenoid kit. Will be making some calls on Tuesday

The hot setup is the GM unit with the CNC plate . Only if you are higher pressure. If stock the OEM is adequate .
