Transmission code 01-P0741

The TFT is a loop and is not connected to the TCC in any way. The PCM power relay feeds power to splice #123, from there it splits into 4 circuits, one goes to the engine control - which I believe is the IDM and ICP - the second goes to terminal #71 of the PCM - third goes to terminal #97 of the PCM and the fourth goes to splice #138 which feeds all the power to the trans. it splits and feeds the EPC sol. and the second leg feeds the plastic wire harness that connect all the other solenoids in order TCC - Coast clutch - shift 2 - and shift 1. All the grounds are made at the PCM. My daughter called me today and told me her lights have never been as good as they are right now. I added an extra ground to both headlights when I changed the plugs. Good luck Lawn boy Mike OB

Seems to be OK , they changed the solenoid pack for the 3rd. time and things seem to be working as they should , I did have a couple of codes show up one to do with a faulty cam sensor , I belive that is because of the Superchip , I cleared them and have not check in a few days ,shows we are up to 15.7 mpg pulling so am pleased with that and no more light flashing , rpm's seem to be down where they should be , maybe we are good to go
