The numbers all look good on the temps. The 5k is not a big load so the temps stayed down. Doing the same thing with 15k is goiong to produce different results but thats another story.
The 2nd gear lockup has always been less than adequate in stock mode. It doesn't want to hold or engage when the load is too high which is when you normally need it in a hard pull. The easisest way to solve that is a manual lockup switch.
Go to radia shack and get SPST switch, about 8' of 18 ga wire and a 33 ohm 1/2 or 1 watt resistor. Scotch lock one end of the wire to the wire that is on pin #6 in the round trans control harness, thats the lockup sense wire. Run the wire to one terminal on the switch. Run a wire from the other terminal of the switch to the resistor. Run a wire from the other end of the resistor to a chassis ground.
This will allow locking the TC on demand and not freak the ECU out. It has to be managed though becuase if you try to stop with the TC locked the truck will literally jump off the ground at some point. All kinds of bad noises ensue also. :-laf
