700R4 shifting gears while locked up?

Can you do this?

I recently upgraded to a 700R4 and am using the B&M shift-lockup controller. I have it set to lock around 48MPH. But the kit instructions say it will lock in 2nd, 3rd, or 4th. So they don't mean it will shift while lockedup , do they? Will this damage the tranny?

where do you guys have the lock up speed set at? It's a driver, not a track car.

yes you can shift while locked up. but the lock up wasn't built for that, and it will fail.(slip) and you'll get a nice chatter
