i have a 2006 ram 1500 . the other day i was driving and went to pas a car the truck shifted out of o/d the wouldn't go back in then when i come to a stop at a stop light it felt like the transmission was slipping or almost like it was in 3rd gear or something so i shut the truck off it was fine i put it on the computer im getting a p0700 code then off that i discovered it said about a 4c pressure switch ratioality and then there was a p0988 code witch is trans fluid sensor/switch ''E'' circuit range/performance. im not a big tranny guy still learning can anyone tell me about this?

 

check the level and color of your tranny fluid. being even half a quart low on fluid can cause these trannys to do some crazy stuff.

when you check your fluid, have the truck up to normal operating temperature. then park on a level surface. apply the parking brake, and put the truck in neutral. leave it running. then check the fluid just like you would check oil. if it is low, only add ATF+4 and nothing else.

 

Yea check your tranny fluid.

I'm having transmission troubles myself on my truck. Not something to mess around with or it gets very costly
