power braking for more then 5 seconds

[JOE L]

Will power braking at less then the engine's maximum stall speed for more then 5 seconds cause damage to transmission?

I say 5 seconds because that is the limit that every drag racing book recommends, but what they don't tell you is if the 5 second limit applies to power braking at just the maximum stall speed.

Also does anyone know what the maximum stall speed is for a 98 Honda Civic EX? I can't seem to find it in any service or owners manual
