Re: Trans Codes P0743, P0753, P1765

I just had the same problem with my truck I would replace the PCM and it would work for a while tell I hit bump and it would blow the PCM (voltage regulator) i found there is a plug on the drivers side of the transmission with 9 wires in it. wire are shorted where the wires go in to to the plug you can get harness repair kit from the dealership for about 75.00 dollars I hope this help somebody because I lost a lot of hair over this one
