I loaded Level 3 (91 perf) and at wide open throttle, I have a violent shift between 1 and 2. Really, really violent. Scary.

Has anyone had any issues like this before? 2-3 shifts fine, 3-4 shifts fine. Normal driving shifts great. Just when I floor it, the transmission slams into second gear.

Thanks for any help! I will probably give Bill a call later this afternoon. Cheers!
