This thread honestly makes my head hurt. Like there is absolutely ZERO way for the engine RPM to magically raise or lower if the speed and gear are constant. It will never happen unless the gearing was changed, tire height was changed or the clutch is slipping.
The only thing I can go back to that I never got a clear answer on was if the diff was replaced and if so, was one of a different ring & pinion ratio used.
The other point of attack I would go after is putting a phototach on the front crank pulley and see if the tachometer in the dash is accurate, along with verifying the accuracy of the speedometer.
High Rpm....low speeds

@jamespmack t
Thats it...did it always fo that? No...
Have I done anything major to the truck outside a previous clutch job? No
Many people preached that I needed a new clutch. Well i got a whole new clutch system replaced. Mechanic said my transmission is thw right transmission inside, and that the geara look fine.
That's it.....the mechanic says the truck is fine. A few other mechanic said the same thing.
I have no clue....but nothing has changed performance wise since the new clutch.
There's nothing left out of my story.... -
I'm just frustrated as anyone else, because mechanics are telling me the truck is fine.
Look at this picture....im in 6th gear going into 7th....18mph 1500rpm....new clutch put in.
I dont know.....Attached Files:

Why would I suggest that? You already did it... to the tune of what, 4 grand or so, wasn't it? If you don't want to answer, don't. But don't insult me when I was trying to help.

I'm at 1500 rpm at 65 mph....so at 60/70 mph....i guess the truck is driving. I don't know -
And what RPM was it running at when going 65 mph before?
