Hello Group!

Does somebody have a screen shot of what the shift adapt values are supposed to be called and the corresponding values?
My scanner is showing 2 lines per gear change and theyre all showing 0
Trans is behaving smooth after initial Adapts Reset but gradually fades into minor binds and flares after about 1500 miles, up to a point where they get worse to justify another adapt reset, repeating the same cycle over and over. I suspect a bad TCM on the TEHCM.

Waddayall think?
