I tried searching around, but no luck. Anybody know how fast the shift speeds are on the TC-SST in the various modes?

 

unfortunately mitsu doesn't advertise shift times for their tranny like nissan did with the gtr, however generally dual clutches shift very fast, around 60ms to go from from one clutch pack to the other. Most of the lag is in the electronics, basically to initiate a shift it takes around 100-200ms because the transmission computer has to communicate (continously) with the engine control via the CAN link so there's a little bit of lag.
