Today I drove down a good stretch of highway, 50 miles running around 65. While running 65 my truck was pulling about 2800 to 3000rpm. (No OD) also the downshift from 2nd to first would be rough.

Well I can put the truck in park and cut it off for a few seconds, cut it back on and all shifts are good. Fluids look/smell fine.

Basically I'm asking is this electrical? Speed sensor? Or should I adjust my bands?

Thanks all. Any advice, experience, or suggestions welcome.
