copied from the LSx section... I need help


Before i did the swap I had a pre-cat o2 go out on the passenger side, so i replaced it w/a Bosch part # 13178 OE replacement. Well it threw a code (can't remember which one) but it was stating the heating element in the o2 wasn't working. So i held off and did the swap and replaced it with another one and changed the driverside too. And they both don't heat up. Could it be an electrical issue? After awhile when the exhaust gets hot they start working, I'm stumped b/c these are the correct ones.

Honestly i can't remember :rofl:

The trans was my issue tonight. I'm throwing codes:

PO740 - TCC Circuit Malfunction
PO785 - Shift/Timing Solenoid Malfunction

I guess i need to load a 4l80e file, so I have to wait on HPtuners to respond back :(

I don't believe the o2 code came back up, but it might after a bit. Thats what it did to me the last time. I think I'm gonna try some different o2's for sure knowing i'm getting power through the heater wires.
