    Default Pause before 1-2 shift at wot.......

    Alright, I've noticed that with my stock tune and 2 different tcm tunes I did. One with tq mgt, one currently without. It shifts much better without tq mgt. What happens is it dead hooks in first and the rpms are climbing very quick, then it pauses from about 5600 to6000 then shifts. It only does it in first gear though. It feels as if it may be normal clutching action for this transmssion but I wanted to see if anyone else has noticed this.

    You line pressures may be low or your WOT speed and/or RPM's may be off

    I bumped up the line pressures and went throught the resets/presets and all seems good now! I also noticed that anything lower than .2 on my shift times felt sloppy. I have them at .25 and it feels better.
