    Well, my 19' callaway tahoe it's like this, if the truck is fully warmed up it shifts and runs great, but cold there are issues if you get on it, when I say issues it will tend to hold the gear longer than needed, don't seem to have the shudder issue, but then again callaway programs the trans as well as the engine

    Are you certain that Callaway changes the transmission programming? My understanding was that the ECM was programmed by Callaway, but they didn't (couldn't) touch the TCM on the 10sp.

    Had a 16 Denali that developed a shudder at 23000 miles.Felt like driving over a rumble strip between 50-60mph only periodically but it got worse.. Dealer already knew about problem and replaced torque converter-TSB 18-NA-355. Problem solved

    The 8 speed shudder was fixed with the 10 speed. As good as the 10 speed is, it's not perfect. Mine gets confused it I hit the gas when the transmission is ready to shift to the next higher gear - It slips badly.

    The 8 speed had the problems, not the 10 speed.

    There are some threads on here of people experiencing issues with the 10 speed as well...
