Can I copy and paste the values in the spreadsheet to my tune or would it be best to make slight adjustments to my current numbers? 5500 lb 1997 2dr yukon with 383 4l60e, 0411, 3.42.

Nice tool, I will be using this for sure!
I have used this on both of my cars with great success, I was chasing my tail on my TBSS trying to get it to downshift correctly from 4->2 on the hwy around 65-70mph, finally remembered I should check my shift points in this spreadsheet. Adjusted a few things, and now it downshifts much better and consistently. No more "thinking" time, it just does it now.
Glad this is still proving useful. :)
Anyway to get this in Allison format or 6 speed?
So I take it no one has tried. Someone had an excel file that showed graphs. Is there anyway to edit for more gears?
Thanks a lot for sharing the sheet
I have one question are those three rules should be applied along the curves ( Also @ WOT )?
(2-to-1)<(1-to-2)<(3-to-2)<(2-to-3)<(4-to-3)<(3-to-4)
(3-to-2)<(3rd Rel.)<(3rd App.) AND (3-to-4)<(3rd App.)
(4-to-3)<(4th Rel.)<(4th App.) AND (3-to-4)<(4th App.)
