Truck runs fine starts fine shifts fine, but under small load like going up a hill the rpms pulsate and doesn't wanna go. Changed tranny fluid and filter still no change, could this be a sensor issue or a vaccum any help would be great.

 

Welcome Aboard Dadof3girls! It would really help if we knew the year of your ride. Stay tuned - a Technician (or member) will jump in shortly to provide a possible solution. In the meantime, don't forget to browse Sub-Forums: Dodge Ram for stuff related to your ride.
