Talk to drag racers because that is exactly how they stage a car until launch...and thats damned hard on a transmission...lotta transmissions die right at that time.
Heck talk to Roy...........WHunter.. He will tell you the same.

I already told you where the rotational energy of the crankshaft is going...........into heat generated by the torque converter. The torque converter dissipates the energy at all times, even at stall speed. The energy is converted to heat within the torque converter. The transmission is not affected by this process. Trans hydraulic pressures are well within operating limits and won't cause excess wear on the transmission
for the three seconds that we are speaking about on this topic.
Drag racing has nothing to do with this topic. Again, stay with me here.......we are talking about brake torque for three seconds.........nothing more and nothing less.
If a transmission dies on brake torque then it wasn't designed to handle full engine output torque anyway. Brake torque didn't kill it. Too much torque killed it. It would have died anyway.
Roy is too busy ressurecting old threads for new members.
