Strange shifting.... need advice asap

I just drove 100 miles w/ the cruise at 60 "best mileage"

And when i got off the freeway i noticed my truck was shifting through all the gears quickly and when i say quickly i mean by time i hit 25 i was in OD and it also jerked real hard as it hit each gear....

If i was on the throtle it wasnt as bad, but as soon as i let off it would shift

Any feedback would be great. I am supposed to head back to work in 6hrs

OD at 25 mph? That's odd. Something is wrong. Not sure what though. Sorry.

Ask a mod to move this to the tranny section. Mark Kovalsky will know exactly what the issue is.

Or you can PM him with a link to this thread, he will help you out. He is the resident tranny genius.

OK so i left for work this morning and my tranny shifted fine.

Sounds like a problem with the vehicle speed sensor.
