Auto Tran & Torque Convertor

Hard to say, since one man's lurch is another man's lunge. My '03 torque converter gave out at 59K, and was replaced under warranty. No problems since, but, in answer to your concern, these cars do appear to have a noticeable downshift - espcially if you have not freed up the intake (K&N panel filter) and exhaust (Magnaflow straight thru's to replace the 2 rear mufflers). Before I freed mine up I got what I call "the motor boat" effect; let off the gas and you get pulled forward in your seat by the engine choking itself down. None of that now, but the downshifts are still noticeable. Marco

I've used the TIP, just for the experience of it. Since it doesn't compare to the manual exotics I've had, I don't really bother with it. But, yes, there is a bit of a lag. Supposedly, there is a transmission flash you can get done at the dealer, putting it into a "sport mode". I realize I tend to be on the conservative side, having spent more money on car repairs, etc., than I care to remember. Freeing up the intake and exhaust gave me the performance I want without that "Oh God, what have I done?" feeling.
