Hey all!
So, I bought a used 2009 1500 a few months back with 157,000 miles on it. I have just recently started to drive it more to work and I have an issue that is hard for me to explain cause I am NOOOOOO mechanic by any means...lol

The problem: When driving UPHILL and I am doing anywhere between 20-45ish MPH there is a slipping feeling that is happening....maybe a bouncing chuggy feeling I dont know. Once I get off the hill or I mash the accelerator it goes away.

What I have noticed is my RPM's dont change when this is happening and my SPEED does not change......it just happens and its driving me insane.

Anyone have an idea of what could be going on? I'll be happy to give more info if I can.

THanks!!!
