Defines time in milliseconds how long SHIFT PRESSURE is held until and how long it ramps to CLUTCH PRESSURE.
This parameter defines two steps: shift pressure time itself and ramp time from SHIFT PRESSURE to CLUTCH PRESSURE. Higher values help smoothing out shift but leaves the shift exposed to post change slip if SHIFT PRESSURE is low. Lower values make shift procedure shorter as CLUTCH PRESSURE transition will happen sooner.
GCU analyzes the shift constantly. Once shift is finished and there is no more clutch slip related to shifting, switchover to CLUTCH PRESSURE overrides SHIFT PRESSURE TIME. It means that even though times may be long if SHIFT PRESSURE is correct, the time will be shortened quickly.
