FEEDBACK CONTROL STRUCTURE
CHU051301030S13
Features
• During shift up with the accelerator pedal depressed, feedback control regulates the clutch pressure on the
engagement and release sides, according to the throttle opening angle and vehicle speed. It also uses past
gearshifts to optimize clutch pressure.
Note
• If the battery negative terminal is disconnected, feedback memory in the TCM will be erased, and thus
gearshift shock may increase. The shock, however, will decrease gradually as the vehicle is driven.
