When going up a hill or going on the highway and laying into the accelerator in 6th gear without going into overdrive, my engine makes a noise similar to a locomotive "chugging". Anyone elses truck make the same sound? The sound intensifies the further I lay into the pedal. Back off and it gets quieter.
It never bothered me until my buddy commented on it and told me his truck didnt do it. Any ideas guys?
