Jeep autotragic failure, 2012

Recommended Posts

2012 wrangler w/5 speed "NAG1" or "W5A580" Mercedes automatic trans.   Limp mode, p0753 "1-2 / 4-5 Solenoid circuit" fault.   Followed diag flow chart which is checking the wires and solenoid for resistance/shorts, all wires were good. Replace TCM.   Not fixed.

Retested.   Same results.  Switched "contact plate" (circuit board at valve body) as an educated guess. Truck shifted perfectly from 3 stops, then back to p0753.

Replaced the contact plate AGAIN.  Did not fix it at all. 


My hunch is that the code is generated from a shifting concern yet the code only covers the electrical side.  I'm up a creek....
