2016 3.6 Ripp supercharged first to second won't shift. goes into rev limiter at wot.

I could use some help with this issue. Car shift good in all other gears. I can't even manually shift after 5000 rpm. Thanks. Chuck

Sounds like second gear is smoked. You also gave almost no info.
What vehicle? What trans? Miles? condition? new build? did it work before? What did you change?

I have a 2016 SXT, 3.6 with a Ripp supercharger. It has been turned with HP tuner to 415 whp. I have 70000 miles on this car. 4.3 0 to 60. 7200 rpm limiter. This 1st to second issue has been a problem since the tune/supercharger has been installed. As long as I manually shift at 5000 rpms the transmission (auto 8) will shift at 7000. In auto wot hits the rev limiter and won't shift.
