SHIFT CHANGE
The clutch is controlled with the optimum timing and oil pressure by the engine speed, engine torque informa-
tion, etc.
Shift Change System Diagram
*1: Full phase real-time feedback control monitors movement of gear ratio at gear change, and controls oil
pressure at real-time to achieve the best gear ratio.
BLIPPING CONTROL
This system makes transmission clutch engage readily by controlling (synchronizing) engine revolution
according to the (calculation of) engine revolution after shifting down.
“BLIPPING CONTROL” functions.
–When downshifting by accelerator pedal depression at “D” position.
–When downshifting under the manual mode.
TCM selects “BLIPPING CONTROL” or “NORMAL SHIFT CONTROL” according to the gear position, the
select lever position, the engine torque and the speed when accelerating by pedal depression.
Revolution control demand signal is transmitted from TCM to ECM under “BLIPPING CONTROL”.
TCM synchronizes engine revolution according to the revolution control demand signal.

7. Install control valve with TCM in transmission case.
CAUTION:
Make sure that turbine revolution sensor securely installs
turbine revolution sensor hole.
Hang down revolution sensor harness toward outside so
as not to disturb installation of control valve with TCM.
Adjust A/T assembly harness connector of control valve
with TCM to terminal hole of transmission case.
Assemble it so that manual valve cutout is engaged with
manual plate projection.
8. Install bolts A, B and C in control valve with TCM.
9. Tighten bolt 1, 2 and 3 temporarily to prevent dislocation. After
that tighten them in order (1
2 3), and then tighten other
bolts. Tighten control valve with TCM bolts to the specified
torque. Refer to AT-236, "
