The 6 speed automatic transmission in my 2012 Ram 1500 Crew 4x4 5.7 Hemi works fine in "D" but does not respond to the +/- button. Doesn't show any codes. What should I be looking for?

 

Is that particular feature enabled on your truck? Do you need to be in tow/haul mode for them to actually work? Owners manual have anything interesting to say about them??

 

if the +/- button is on the column shifter lever...a broken wire in the shifter are common. to verify refer the steering column trim and you can follow the wire out of the shifter to a Christmas tree pin retainer...the wires break at the retainer....repair the broken wire.
