I have a 98.5 2500 24v auto. Driving down the road in between 40-60 mph the truck acts like it's shifting in and out of over drive. I'm get codes P0222,P0122,P1693. I've tried resting the APPs didn't fix it. I also fixed a broke wire coming from the sensor to the ECM. All the grounds and hots been cleaned. The APPs is a timbo that was put on 2 weeks b4 I bought the truck 4 months ago

 

Please someone help

 

Sounds like a transmission issue.

 

Its your alternator. Test it for AC noise. That will cause your transmission to go in and out of OD.

 

I fount a ground wire touching the alternator braket

 

Mine does it too
I've found if I clean the batt terms, both pos and neg, it cures it
