Has anyone had any trouble with the 4.0 engine with the transmission shifting way too early, when it does it feels like my truck is working very hard to pull the truck resulting in about 8 miles per gallon I would appreciate any help you can give me.I have 800 miles on the truck now. I have driven two other that do not do what mine does.

Welcome to the forum.

I have moved this thread such that you may receive more feedback.

Not many with that size engine around here but, there are a few.
