Hey All,
I currently own a 2012 Ram Big Horn addition my first Ram. Great truck by the way!!
I do have a question about the tansmission.
When I come to a complete stop I can feel what seems like the transmission shifting back down to 1st gear. I am not sure this normal for a Ram to do this any suggestions on what is going on?

 

It is happening when your fuel tank is around 3/4 full, isn't it? That's fuel sloshing around the tank. Feels like a jolt or transmission shifting or unlocking but it is fuel-related. Weird, I know. But next time it happens look at your fuel gauge. It will be in the 3/4 full ballpark. This seems to be more prevalent with the 32 gallon tank, but it has been reported with the 26 gallon tank too.

My 12 sxt did that also usually after I changed my driving style never did find out what it was. Interesting theroy about the fuel tank
