When taking off truck has little power, but if baby the throttle truck will perk up after 15 MPH. Truck will run at 65 MPG, but RPMs are at 3,100.

The transmission will not shift from 15 to 65 MPH. No codes on dash. I replaced the speed sensor and that did not fix.

Any ideas?

Good morning,

This sounds like you have a seized clutch pack in the transmission that gives you constant one gear all the time.

I would change the fluid and filter and look for any debris in the pan.

It is not electronic because if it were, it would code. It sounds like you will be either rebuilding it or replacing the transmission.
