It's not the tranny I'd worry about, but the stress you're putting on the engine. The crankshaft is being forced to slow down rapidly while the cylinders keep firing. It's better just to use maximum braking power from the brakes, that's what they're designed to do.

There has to be a "study" done on this somewhere, I'd be interested to see what it might say! I always did that with my Mustangs, but not everyday, just occaisionally.
