engine lugging

[dmaxmule]

Truck has always lugged at idle and slow speeds. Took the truck to dealer and got updates. It seems to help some but lugging is still in lower gears. It was doing it in all gears. ADVICE??

Not knowing what you call "lugging", but what I call "lugging" is cured by useing the proper gear for the load and rpm of the engine. If the engine is lugging then lighten the throttle or shift down to the next lower gear.

After reading your other post, could be a bad flywheel, but would think you could tell there had been a change, and that you knew you were not geared too high for the load.
