All,

I have an 1151A1 that won't shift. I T-shot it and came up with a Code 22 (Low Volt). After going through the remaining, it came down to the TPS bad. I swapped the TPS into another (known good ) trk and it shifts fine. Could the PCB be causing a low voltage to the sensor? I have checked that the new commo install didn't interfere with the operations all looks good there. Any suggestions?

thanks,

SFC KJ
