P59 Shift with convertor locked tab
It's been a couple years since I have looked for this, but could have sworn there was an option to check if you wanted the computer to always disengage the convertor to shift gears or not. My 2005 Silverado 6.0 4L80E has 3rd gear lockup from the factory and after the first shift kit, it would engage 4th before the convertor could release, then unlock and re-lock every time it went into fourth gear. Super annoying and therefore I changed the tune to leave it locked during the shift. Now I can't seem to find it in the tune anywhere. Thoughts? Attachment 96115
