    6l80e auto upshift in tutd mode?

    I've seen a few comments on the Internet about people making 6l80e where when in manual/tutd mode the car will still upshift at a set rpm at WOT. Is there a way to do this with my 2008 Corvette? Any help would be greatly appreciated.

    Open your tune and have a peak cuz. For example in my 6L90 tune the OEM had TUTD to force a shift at 6,000rpm. Winding that table out to the max allowed me to limiter bash for as long as I wanted.

    That is how my car currently behaves. I WANT it to automatically upshift if I go WOT at a set RPM and not hit the limiter but I'm not sure how to do this.

    Your current tune is calling for auto upshift at full throttle with TUTD. But your part throttle is set to hold the gear till 312mph (never shift until you tap up). I've adjusted the part throttle shift speed to match your current auto mode speeds.
