Ok so ive noticed when im doing like anything over 40 or so specially like 70 or 80 as soon as i let off the gas it slows down REALLY fast like i put on the brakes. Is that normal or does it sound like something is wrong?

 

These trucks are heavy and boxy (lots of air resistance). My truck does the same thing. If it really bothers you, you could change all the drivetrain fluids and put in new wheel bearings to try to eliminate some of the friction.

 

alright i just wanted to make sure it wasn't a tranny deal or something crazy this is basically my first auto and deffinately my first driving brick. but thanks.
