TH 400 Switch Pitch

I posted a basic wiring schematic for a VP TH-400 Transmission as well as an article that I wrote some time ago that details exactly what a switch pitch is. I have been running the car with the VP 400 in it for some time and have nothing but good things to say about it. I run a step rear gear (3.08) so the high stall really helps that car get off the line, but when I am crusing down the road I can switch to low stall mode for better efficiency and sharper throttle response. I took the car to LACR and played around with the setup a bit and I found that I got my best E.T. and MPH if I left the car in high stall until the top of first gear then switched it into low stall mode.
