Take a very specific instance:
Increasing torque by 1.5 will decrease individual component life by about 3.5x.
More importantly you will increase the possibility of catastrophic failure at max torque (called stall torque).
From that standpoint, think of your AT as a consumable item behind a boosted motor. Like a really expensive clutch.
