If I leave the lever in 3rd or OD it just holds 1st and wont shift out? I have the shift mph set a few less then desired and the shift point at 6,000 , it worked well with the 4l60e tuned like this.
monitor the shift solenoids with a scanner and ensure the pcm is commmanding the shift, if it is, then you know what it isn't.
