FEEDBACK CONTROL OUTLINE [JA5AX-EL]
id051705690100
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 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.
