I have a 2014 1500 4x4 with the 5.7 Hemi and 6 speed, 96,000+ miles. I do a fair amount of light towing (Scout trailer, robotics trailer, RZRs), I believe that the previous owner did similar.
I towed my car hauler with my RZR and my dad's quad about a 1/2 hour through some light hills between 45-55 when my dash was flashing at me that the transmission was overheating. not sure for how long because my gas gauge had failed recently and the dash was already giving me a low fuel warning.
The fluid was brown and ugly, so once i got the fuel pump changed, i did a fluid and filter change. I dropped the pan, changed the filters and refilled with ATF+4 synthetic. I then removed the cooler lines and ran a couple of gallons out of the lines, keeping the tranny full of new fluid. I also kept the return line in jug of new fluid.
I did notice that the flow out of the lines never had much for pressure. I also filled the cooler full of alcohol and blew all of that out till it was clear. (it wasn't bad)
I checked the level and it wasn't on the dipstick so I bought more fluid and filled it up the next day. I drove the truck about 8 miles and shut it off, trans temp stayed under 125. An hour or more later i drove the truck another 4 miles and it was in drive, but the indicator was showing manual mode, 4th gear. I couldn't adjust it either. I had to back up and the trans acted like it had a high stall converter in reverse. Then back in drive, it was showing manual 4 again and to move was about 2500+ RPMs. I checked the fluid and it was showing barely on the dipstick. I added fluid, but it never changed the way the trans acted. Temp never got over 125. I left it where it is and my son is dragging it home on the trailer today.
Any advice on what to do next?
