For the last couple of weeks I have been noticing that for example while coasting down a hill and upon reaching the bottom and reapplying the gas pedal lightly the rpm's would tach up to about 2000 or 2100 before it gets back into gear (so to speak). I am usually only going around 30 to 35 mph when this happens.

I took the truck by the Ford place at lunch to explain this, and the service manager looked some stuff up; and it turns out there is a TSB for this problem. They took my truck back and reprogrammed it.

The problem is now gone, just thought I would share this for anyone else experiencing this symptom.
