Clutch engagement control for motor vehicle automatic transmission has locking switch producing shift lever position signal and manual valve to control clutch engagement direction

摘要

The clutch engagement control for a motor vehicle automatic transmission has a locking switch (56) producing a position area signal for the shift lever (51). A manually controlled valve provides oil pressure for altering the position value of the position area of the lever with respect to a forward drive clutch (32) or a rearward drive clutch (33). A control (60) limits the clutch engagement dependent on the position of the shift lever.
