I can't find who said it, but someone posted that one of the companys are doing some R&D on getting the Automatics to shift quicker and not so lazy.

Anyone remember what company or company's are in work on this?

Never seen the fix you are mentioning. There is no much delay time when it shifts, at least on mine - but you have to push the pedal far / fast enough. Much faster in manual mode though.

I never put in D, I always have it in autostick...if you shift at about 5K rpm it runs smooth and it's pretty quick.
