Transmission Changes 01" VS 02"

For 2002, Honda has added a glass rear window with a defroster, an improved transmission and a more powerful audio system. There are also a handful of minor changes that only '00-'01 S2000 owners would notice, such as chrome-bezel taillights, an upgraded center console, door panel net storage pockets, a new shifter knob, an aluminum-accented foot rest and silver trim interior accents. There's also a new color for 2002???? What is the different in the TRANSMISSION they'r talking about?? thinking of buying 01" 32K for 13k
