I've got a 2014 L86 silverado with the A6 transmission. I have the shifting down almost exactly how I want it, but am still having a little bit of an issue. The initial shift feels great, but once it gets into 2nd, 3rd, and sometimes 4th, under medium throttle, it seems to slip for a couple seconds before actually locking into the gear. Here is my current trans tune
Trans Only.hpt. Ive done everything I can think of so far.
The next step I think I'll take is adjusting the Final - Normal and Final - Special, in the Shift Timing>Upshift>Transition Time section.
Am I on the right track? Thanks
