Model: 02 WRX Mileage: Apx. 100k on transmission Mods: LW flywheel act flywheel, act street HD pressure plate and clutch disk, 02 WRX auto drive shaft and r180 rear diff. This happens regardless of speed it seems to happen less when the fluid is a little colder. Brand new up to lvl xtra s is in the transmission. It only happens on down-shift even if its rev matched and double clutched. Im thinking possibly syncros but it seemed weird that it didn't do it shifting up. Any thoughts on the matter
