Big Bore,
Here is a comparison of a stock PMT1 program and my Heavy Towing program that I use while hauling a few tons of hay. The windows in the first column are 1-2 shift speed, 2-3 shift speed, and 3-4 shift speed. The second column is 2nd gear TC lockup, 2nd gear TC unlock, and 3rd gear TC lockup.
The first column in each window is factory TP voltage, the second is tow program TP voltage. The third column is factory speed while the fourth column is tow program speed.
Tell me what my 2nd gear lockup does.....

I like it that way!
You'll probably have to save it and blow it up since it's so small.
