I'm having trouble with my half ton. 2 torque clutch converter solonoid codes and 2nd to 3rd solonoid code is coming up on diagnostic. doesnt shift down so starts out in third. diagnostic says solonoids are recieving low voltage readings. just had those solonoids replaced and two weeks later back to the same problem. any ideas out there?

 

I would think you need to swap out the entire engine wiring harness and go with the stock 535 059 ecu and matching afm.

 

Hoffman Zac, what model year and mileage is your vehicle?
