Going down the road and stepped on the gas a little to speed up and rpm's rose but didn’t really speed up and the rpm's kept fluctuating. I need help please.

Good afternoon,

So the engine revs and the truck does not respond?

Sounds like it is slipping.

How long since you changed the fluid and filter in the transmission?

Are there any codes in the system?
