The transmission is doing the exact same thing it did when I brought it in. Makes me wonder if the Trans Specialist even test drove the vehicle when he finished. Disappointed to say the least. Other than this issue,love the truck.Looks like we will be going in again very soon!

I don't think they performed the TSB. I think they just reset the adaptive learning on the transmission without reprogramming the pcm.

yup i noticed this, the torque converter doesn't lock-up until tranny fluid reaches 105 degrees, it has to do with heating the catalytic up, so i'm told

My third gear bog has been cured..... Bought a tuner from Mike @ 5star, had him leave the TQ converter locked in 1-4 shifts. Night and day when compared with the stock shift strategies.
