Had a code for crank position sensor, replaced that and code along with engine diagnostic light went away.

Service Stabilitrak, Traction Control warning, rpm gauge not working and hard shift from 1st to 2nd still present. Anyone have an idea before I get raped at stealership.

I would run the codes again to see if there are any in history that could point to something.

Well, that makes sense, the brakes are required for traction control.

Ok, ABS, tach not working, hard shifts, all are electrical.
Did they all stop at same time?
If so, look for a blown fuse, or broken wire (where you worked at the CPS)

Rpm gauge not working is defo a Crank sensor issue. I had a truck with this issue. Hard 1-2 shift , service stabilitrak and traction control working.
The crank sensor was the issue.
ABS Brake switch just illuminates the ABS and traction but not Hard shifts.
Check the wiring.

Sounds like it might need a crank sensor relearn procedure.

Those warning come up for tons of ****. Mine went off and put my truck into limp mode a while back and all it was was a bad connection on the brake position sensor
