So yeah new truck new issues, lets see if someone can offer a suggestion, basically the trans doesnt like to shift into 3rd gear under normal driving. And under very gentle driving (say in the rain) it likes to come out of gear and start looking for first. Anyone have any suggestions? I am thinking T56 but my bank account wont support that right now

 

anyone?

 

if its a 4l60e you may have a controller problem
