4l80e TCC not locking with frost harness
WEll I originally did the relay method and the truck would not take off in first gear on its own. I would have to unplug the relay and it would take off on it first, then plug the relay in for it to go through the other gears. After messing with it (and not figuring it out) I borrowed a frost harness from my friend and put the wiring back to original. The harness fixed that problem, but the stock converter feels way too loose, and also the torque converter doesn't seem to lock up. Does anyone have any ideas or suggestions for me to check? Thanks guys.

For GenIII all he needs to do is MAX OUT the enable temp fields for the P1870 Diag (this is NOT setting the DTC to No Error; it's making the DTC not run by setting the enable temp to 495 or whatever max is). After that, set P0785 and P1860 to No Error Reported in the DTC list.
