You can also play with the transmission itself to create manual valve body, if you wanted to. Also, you can change the stall speed of the torque convertor, but that will affect your TC lockup as well. *You won't have it anymore*.
I'm not sure if you can modify the signals to or from the TCU to change the actual shift points of the transmission, but you can usually just change the sizing of the oil passages in the valve body so that the fluid doesn't build as much pressure as fast, which means that it won't shift at the same RPM. (Shifting is normally controlled by fluid pressure.)

Any kind of mechanical shifting (besides the shifter, which I do, force it into 2nd) is out of the question because of the electronically controlled tranny. I thought of changing valves, but after going through the factory guide, that was out of the question.
BUT I do have a plan. At this point the only sensor the PCM gets is the VSS, so my idea is to skew it. I have a PIC processor that I am programming to read the VSS and then spit half the pulses (or less) to the PCM and it will think I am driving slower than I really am. Then it will stay in gear longer, and I won't have to do anything but shove it into D and drive off.
