Hi, just had that happen yesterday camping in Island Park Idaho, left the camp spot, got to the top of what we call the Ashton Hill, topped the hill shifted down to second gear to decend the hill which is some what steep as I always have done (2015 Ram ecodiesel 120,000 miles), it quit on the way down, towing camper and RZR trailers. pulled over to the side of the road, called my son to come and get us. had to undo the drive shaft to roll it on the trailer. what a hassle. anyway long story short, using my autel code reader, pulled code P0336 which is a generic code for a crankshaft positioning sensor, I had noticed last Feb a slight miss, everything i have read this common, So Monday we are going to change the sensor which requires removing the transmission. I will try to keep you posted.
For future reference:
MANUAL PARK RELEASE — 8 SPEED
TRANSMISSION
In order to push or tow the vehicle in cases where the
transmission will not shift out of PARK (such as a dead
battery), a Manual Park Release is available.
Follow these steps to activate the Manual Park Release:
1. Firmly apply the parking brake.
2. Using a small screwdriver or similar tool, remove the
Manual Park Release access cover, which is just above
the parking brake release handle, below and to the left
of the steering column.
3. Using the screwdriver or similar tool, push the
Manual Park Release lever locking tab (just below the
middle of the lever) to the right.
4. While holding the locking tab in the disengaged
position, pull the tether strap to rotate the lever
rearward, until it locks in place pointing towards the
driver’s seat. Release the locking tab and verify that
the Manual Park Release lever is locked in the released
position.
5. The vehicle is now out of PARK and can be towed.
Release the parking brake only when the vehicle is
securely connected to a tow vehicle.
