Looking to do some modifications to the shift table on my 94 c2500 with a 4l60e trans.
I want to get the mph up from 1st to 2nd and 2nd to 3rd. Right now it shifts into 2nd at 15mph if my foot is in it or not and into 3rd at 28 or so...
Here is one of the tables I found but I have no idea what to change and how to do it so I need some
help and plain English please..
