    10r80 1-2 short shifting no matter what commanded no visible limits

    guys I could use some input on troubleshooting why my truck (f-150 Ecoboost) consistently short shifts under commanded on my track boost launches in 4High every time and the rest of the gears (2-5) shift at or around commanded, i've matched all my tables I use Base, sport, 4x4 and even tried setting the commanded OSS to a little higher without gaining much of anything. everything I can think of doesn't work. its under the torque request and all id just like for my 1-2 shift to shift at 6k like im asking instead of 5400-5700 lmao

    There should be, its part of what's essential to getting shifts on command. Its a very possible cause for short shifting. Murfie explained it in the 6R80 thread on this side of the forum.

    I haven’t seen any tables for fill time in the 10r80 cals.

    Yes but 10R80 is completely different animal and has no clutch fill times to tune.
