I was on my way to work last week at around 6 am and had a shifting problem with my truck. It was rainy and cold outside, and I had noticed on several mornings since the weather has turned cold that the truck revs high, and doesn't want to shift when I first start driving it. As I was driving last Wednesday, it did the same thing, but after a mile or so down the road, the truck died and the "engine symbol" and "oil symbol" dummy lights stayed on on the dash. I had to let the truck roll back down the hill and off to the side of the road. It would not even attempt to crank again. A couple hours later, I was able to start the truck right up, and after putting a scan tool on the diagnostic port, found the fault code P0700 showing. It was something about an error to the PCM from the transaxle. Took my truck to the shop and it was diagnosed that the transmission pump was failing. Apparently, with the automatic transmission on this truck with the 4.7L, the valve body is made into the transmission pump allowing it to be a fully electronic transmission. The mechanic said that they had had this problem with several vehicles including the Jeep Liberty and our trucks! The transmission had to be dropped and the pump replaced, the tranny flushed, and filled with new fluid and both filters replaced. The total bill with labor and parts was $1750.00!!!!!!!!!!!!!!!!!!!!!! I almost lost my lunch that day. Two weeks before Christmas too!!! Thanks Dodge.
Pump was around $375 by itself and fluid was $8/quart and the tranny holds about 12 quarts!!
Has anyone else had this problem with theirs???

I bought the truck cause I thought I found a good deal. We needed a four door vehicle, and my fiancee can't drive stick and wasn't really interested in learning! This is the first automatic transmission vehicle I have owned in about 8 years. I had a 05 Jeep Rubicon before this truck, and I wish I could have kept it AND got another vehicle.
The transmission didn't really shift hard, but you could definitely tell that on cold mornings that it wasn't operating properly. I would have to give it some gas, then let off, until it finally shifted. It was DEFINITELY noticeable. With these transmissions, they can test them while still in the vehicle and tell you whats wrong without having to drop the tranny. Of course, that also means they are expensive as sh** to work on, apparently. What a crock!!
There was a TSB that replaced the filters, flushed the tranny and made sure the line pressure was correct. That TSB is supposed to fix this.
Also, this tranny doesnt like neglect. If you are getting close to suggested intervals for service, I would follow them. its in the owners manual if you need an idea of what time frame to do what.
I usually just have the dealer do it, since my uncle works there he can do it when they are slow and save me some cash. But any tranny shop can do the work. Stick with the guys you trust.
This isnt anything "new"
it has happened to a lot of different vehicles, Ram, Dak, Liberty, Cherokee, Wrangler... and its not just dodge, chevys electronic trannys have to be dropped to be worked on too... any fully electronic tranny has to be dropped. (unless there is some foreign automaker that has figured it out.)
