TRNW-2: 6L hp tuning

[Steve Everett]

   I'm not messing with any of the pressure settings,  I only change lockup
apply speed and gear,  I know many people are zeroing out the tcc slip, but
I'm not disabling the DOD,  as I'm not going thru the dlc,

    Shop I was at 3 or 4 months ago was disabling DOD,  ramping up the tcc
apply pressure, and sometimes increasing shift pressures, and they still
had 6L80 comebacks, mainly because of things they weren't doing though
