View Full Version : Quick shift without lunging?

I have been toying with my 6L80 tune trying to just get clean, quick, positive shifts. When I first load a fresh tune, it shifts perfect and I log the shift times that feel good.

When I enter those values and load that tune, it shifts great for a while, then the shifts start getting lungy (best way I can describe it). I know it should be possible to have a shift feel such that you dont really feel like you're going through the windshield nor kicked back, but Im having a hard time finding the feel and KEEPING that feel.

Am I missing something? Stock 2011 Silverado 5.3L E38 / 6L80 T43.

I'm not much help with the 6L80E trans... but if it is similar to LS1B and 4L60E what is happening is adaptive learning is fixing your tune!
