5. Set manual shaft in “P” position to fix idler gear.
6. Tighten lock nut of idler gear to the specified torque. Refer to AT-230, "
Component".
CAUTION:
Lock idler gear with parking pawl when tightening lock nut.
7. Measure turning torque of reduction pinion gear.
•When measuring turning torque, turn reduction pinion
gear in both directions several times to seat bearing roll-
ers correctly.
•If turning torque is out of specification, decrease or
increase thickness of reduction pinion gear adjusting
