    Hi I have a 2000 silverado 5.3L v8 and my C.E.L came on and I put code reader on and these codes came up

    P0332-Knock sensor signal frequency outside normal range ( bought a set gonna replace them this weekend)

    P0452- fuel tank pressure sensor circuit, low voltage

    P0740- torque converter clutch enable solenoid circuit

    P0753- 1-2 shift solenoid circuit

    P0758;P0785- 2-3 shift solenoid circuit

    P1860- torque converter clutch pulse width modulator solenoid circuit

    Those are the codes and showed up. And every time I put it into D it seems to take off in 3rd. But when I put it into 1, 2, 3 she seems to drive fine. I had this truck for about over a year now and need help before I dump a piss load of money in it for nothing. Please help

    Might be a broken wire, or corroded connection of the wiring harness going to the transmission.

    Sorry to ask but where would I find the wiring harness. Lol I've never really got a chance to look under the truck. And how much would a harness be. I'll take a look tomorrow after work. I also took it to a transmission shop as they said it was a wire that was loose and the changed it. But my dash don't show anything too. Just when I have it on ACC when I go to start it, it shuts off, it pretty much has a mid of it's own I guess LOL

    Look for a connector on the side of the transmission.

    That's the one that should have two wires. That's the one I found
