Had my trans rebuilt by a local builder that has done numerous powerstroke trannys. Went on my first trip pulling my fifth wheel, tourque convertewr keeps locking and unlocking 50 -60 mph, I took it over to him today with the trailer on it and let him drive it with all of his fancy snap scanners, the tranny started doing the same thing so he pulled 2 codes KAM and cps, I had my old cps in the glove box so I put that in it didnt help I have not pulled the superchip out to see if that works, Any thoughts or I deas would be greatly appreciated

 

Judging by your truck 02 you got the wrong forum.
