yeah a good shift kit, will help alot with quicker shifts and everything, the only problem is the actual automatic tranny being a piece of shit. basically anytime you start adding power to the car, the tranny fails like a little bitch. therefore, if you plan on putting more power through the engine, your only gonna start complaining about it breaking in the near future. if you intend on just keeping it stock, or slightly modded, then you should still be ok, and the shift kit will help. my step dad had a modded chevy truck with a shift kit which was pretty sick, it would smoke my mx6 all damn day.
