My son has a 2001 S-10.Has the 4-cyl engine with the automatic tranny.Says it is acting up on the highway.It will run fine then all of a sudden it will come out of overdrive and downshift and the only way he can get it to go back in overdrive is to stop and start over again.Does this 2 or 3 times when he is out on the highway.Fluid is full and clean.Any suggestions?

Depending on transmission type/model, It may be that the upshift/downshift spool valve is malfunctioning. Causes of this vary from old age and wear, (binding valve or low apply pressure), Intermittent electrical apply solenoid, to possibly a governor malfunction. You might also check the TV cable adjustment. This is potentially cured through adjustments repairs made by dropping the pan by a qualified technician familiar with your particular trans. I'd invest in correcting the problem now as it will only get worse to the point of failure.
Good luck.It's never really finished...and faster is always better.
