Short shift to second and then violent downshift back to first on launch

[killer_s4]

I’ve seen videos and for the life of me can’t find them anymore. Can anyone help me out and link a video of when TCU’s had the issue where you would launch and it would short shift to second and then when it hooks it drops back down to first?

Thank you.
