Strain on the brakes? What strain? Keeping the 2 ton car the brakes just stopped still? As said the shifting the trans around via the shifter likely causes more problems that siting at idle in D. the clutches or bands are not in play with the car not moving or shifting up or down. The torque converter is spinning but the fluid is only generating a slight amount of torque with the fluid bypassing. In N other stuff is spinning internally just not meshed.

Funny side. Before we met my wife dumped a guy in part because he had an annoying habit of "shifting" his automatic equipped car. His loss...
