Made a trip to Pigeon Forge Tn. towing my 5th wheel and the transmission started slipping in 4th and in OD. It dosen't slip all the time, just when I would start to accelerate going up a mountain. As it began to slip I can back out of it just a little and it would stop. Called the dealer and he said bring it in and they would get it fixed. My truck only has 40000 miles on it, so I got lots of warranty left. Just another story for the 47RE.
I can't afford to do what I want to right now, so I'll let them fix it.

 

Mine only had about 33000 when it started slipping. It was expensive, but I don't have to worry about it anymore! Also a lot more fun to drive now.
