    6R80 file requests for some 6f50 funing.

    Does anyone have a tuned 6R80 transmission file vs a stock one that I can do some comparison with?

    Supposed to have the same shifting strategy as the 6F50 and I think it would go a long ways to help me in figuring out some things.

    I've done some tweaks to mine and it is mostly pretty decent except for a slow 2-3 upshift at 3/4+ throttle that I'm trying to get fixed.

    Trying to speed up overall shifts as well in the lower throttle regions to pull out some of the slip with stock like shift feeling in the 3000 and lower range.

    Not looking for harsh stuff, just some decent improvements.

    Thanks in advance.

    I've had good luck with my 6r140. I believe that is basically the big brother to the 6r80. I found the most success by increasing the oncoming clutch pressure to speed up shifts and I reduced the adaptive times as well. I had to make considerable changes to get it shifting how I wanted.
