Hey guys my 07.5 LMM will not shift out of park. The display looks normal, and about 4-5 hours earlier I drove it with no issues. No engine codes, other than a glow plug light. The shift lever won't budge. Any ideas or thoughts, it is stock other than a simple trans go kit installed over year ago. Thanks

Yesterday I tried turning it either direction without any luck. Thanks

It feels like I'm trying to shift it with applying the brake pedal

Maybe a Shift lock control actuator? Anyone have this experience? Thanks

FYI. Shift interlock solenoid was the issue in case anyone else has same issue , Easy fix to do on your own. And if you have 2007.5 dorman part number is 924-977, gm part number is 15775841.

Would replacing this shift interlock solenoid mess with my brake lights or cruise control? They are no longer working

The issue was my brake controller switch
