OK, I found it. It wasn't in the archives - it wasn't even a year ago. Seems like forever, though.

PM sent. For others' reference, the Torqshift tranny gear ratios (according to the person who developed the SCMT programmer) are:
"Here are the ratios:
1st: 4.219:1
2nd: 2.531:1
3rd: 1.656:1
4th: 1.219:1
5th: 1:1
6th: 0.7:1
The shift schedule when accelerating is 1,2,3,5,6
4th gear is not used on upshifts.
There are also some situations that dictate a skip of other gears.
(A 1-3 shift occurrs often in low load, low throttle situations)
The DOWNshift schedule is 6,4,3,2,1 (it will skip gears other than 5 depending on the situation).
Notice 5th is a 1:1 ratio, but 4th is a 1.219:1 ratio....
4th Gear allows for engine braking on decel and this is why it is used for decel only instead of 5th gear.
So when you make a WOT run and you think your truck is shifting 1,2,3,4,5...it is, but it's actually 1,2,3,5,6"
