No idea, but much less than you think. I dropped TM off for 1 pass on our C7 corvette when it was running 10.8s to see how it would fare and it slipped pretty good on each shift. The A8 does not like full torque shifts at all.

4L80 is basically a TH400 with overdrive, so once built, they will handle anything you can throw at them. The ATI T400 MAX DUTY we're using here is rated for 1800HP and up.

Unfortunately the Camaro didn't get finished last week so no testing yet. Hopefully in the next couple weeks.
