don't recall him ever saying it was requesting overdrive

 

That would be something to look at. There are a few conditions the PCM wants before it will allow overdrive..... vehicle speed, engine load, trans fluid temp, etc. If the PCM ISN'T asking for O/D, need to find out why. If it is, and you aren't getting it..... that is going to be an entirely different problem.

 

ok , maybe speed sensor?? will have to probably recheck with computer hooked up . not sure what to try next. thanks
