When I let off the fuel pedal when slowing down for a stop, the transmission shifts between 2nd and 1st one or two times before settling into 1st like it should. I am thinking it might be the throttle position sensor but not sure. I replaced it last year and the truck has run fine until a few weeks ago.

Any help would be greatly appreciated.

Thanks.

 

Doesn't sound like the TPS but it's easy enough to check.

Thanks Bill...I will check it today.

 

If you have a 47RH the TPS only controls OD and CL. Has nothing to do with the One, Two, Three shift.

The 47RE may be different.
