New working theory on transmission (and engine mount) failure...throttle anyone?

I have a new (to me at least as of two days ago) theory as this why this car and others break trannys.

Or in my case, the passenger-side motor mount, twice, in the last three years, even with the Ingalls Stiffy engine damper I have had installed for the last year.

My theory is this - the throttle is wayyyyy to sensitive right at open and close. As in, your engine is spinning at 3000+ rpm, and then you slam the throttle closed by lifting your foot to brake instead of easing off the gas pedal and allowing the engine to slowly transition from adding power to taking it off with engine braking.

My thought is that if you aren't smooth, the throttle slams closed and the engine rotates and puts stress on other components. In my case I'm lucky, got a strong tranny, and I break motor mounts.

I talked to a lady at a gas station who happened to be putting washer fluid in her 01 accord v6. mentioned something, and we get to talking about her tranny being replaced and so i asked about the symptoms and stuff. Sounded like I might be right.

The motor either brakes the mount hanging off the front, or the tranny hanging off the back.

I have a bright idea about changing the round throttle cable cam for an oval one and see if that makes the on/off transition smoother.

I welcome your thoughts!
