Sorry guys for being late, but there was some playoff hockey I had to attend, and my Flames just burned the Canucks. I hope they will manage to burn them another 3 times. Go Flames!!!!
So attached is the pdf. If you ever have the 1-2 hard shift situation, and you know 100% that the ATF level is good and the filter is not clogged, just try to re-flash the latest software. This is for the 6HP26 transmission with Mechatronic.
When programming, you have to select GKE (as opposed to EGS in pre-facelift models). The software later will ask for some numbers to process in the EGS (although you selected GKE), but this is normal. Read very carefully the attached pdf, because it spills out the exact numbers that have to be entered for a 4.4 or a 4.8 model. The pdf is SIB 24-01-06
