I have swapped in a 2005 LQ4/4L80E and I am having some issues with the TCC dragging I think. The truck cuts off in R and D at a stop, and driving up to temperature, I can smell ATF (which I believe is cause of the TCC getting hot).
I used a standalone harness from Current Performance, and they have the few wires to splice into the original to make everything work as it should.
I am trying to perform troubleshooting, as I had the transmission rebuilt, and a shift kit installed with a new Torque Converter due to the old transmission having milky fluid from sitting out at the junkyard, but showing the same symptoms as this newly rebuilt one. I unhooked the electrical connector, and it does the same.
I have not hooked up the brake sense wire for the TCC lockup (purple) because I haven't located the wire in/around the brake switch which gives 12+VDC and 0VDC when the brake is pressed. Does anyone know if there is such a wire in the 1995? I am thinking there should be as the original setup was a 5.7/4L60E.
This hookup to work the TCC Solenoid is my fist step before I buy the Sonnax Pressure Regulator valve for the 4L80E.
