Let me start by saying thanks to all who contribute to this site. I have found it very helpful in fixing other issues I have dealt with on my dodge. I have had the truck for about 10 years; overall, it has been good to me. I hope that I don't have to replace the transmission but I fear that I likely will. So with that being said my issue about a year ago, I was pulling a camping trailer (that was within the weight limit of what the truck could handle safely for the truck) when a transmission cooling line popped off at the transmission cooler by the radiator. I pulled over as soon as I could. I put the line back on and refilled the transmission. However, ever since that time, the truck has not been shifting right. It seems to have no power in lower gears. The best I can describe it is it almost feels like you are trying to start out in 2nd. Now I will note that if I put it into 1st manually it seems to do much better than I shift into 2nd and then into drive. This helps but still, it does not feel like the power I had in the truck before I blew off the trans cooling line. Here are the things I have done so far in hopes that it would fix the issues. I changed the Trans Filter, Pressure Sensor and Governor Pressure Solenoid. Here are the codes I pulled off the truck, P0711, P0712, and 1756. Once again any help is much appreciated.

 

P0711 Trans Temp Sensor, No Temp Rise After Start
P0712 Trans Temp Sensor Voltage Too Low
P1756 Governor Pressure Not Equal to Target @ 15-20 PSI
Did you have these codes before you replaced the parts?

 

Looks a lot like the wrong year parts got put into the trans.

 

Yes and No the codes I had before were P0712, P1757
on a side note, I did have these other codes as well but I don't think they are related just in case I thought I would list them as well because maybe they are related.

So codes I had before I changed the filter and solenoid
P0712, P1757, and P1281
After a filter change and around 70 miles of driving later the codes that came up are
P0645, P1281, P0712, P0711, P1756

 

It's certainly possible I picked up the wrong year kit from Amazon it said it would fit my truck but you never know. The parts looked the same as I part I pulled off so I figured I was the correct stuff.

 

Link to that kit you bought?

 

sure thing -

 

Well, theoretically, its for the correct year......

Check the 8 pin connector at the trans. The wires tend to pull out, and short right at the connector.

 

I'm having a hard time finding an 8-pin connector on the trans casing. Can you give me an idea of where it would be on the trans?

 

Drivers side, about halfway back, plugs straight down into what would be just above the valve body.
