CLUTCH AND BAND CHART

*1: Oil pressure is applied to both 2nd “apply” side and 3rd “release” side of band servo piston. However, brake band does not con-
tract because oil pressure area on the “release” side is greater than that on the “apply” side.

*2: Oil pressure is applied to 4th “apply” side in condition *1 above, and brake band contracts.

: Operates.

A: Operates when throttle opening is less than 3/16, activating engine brake.

B: Operates during “progressive” acceleration.

C: Operates but does not affect power transmission.

D: Operates when throttle opening is less than 3/16, but does not affect engine brake. Shift posi-

A/T CONTROL SYSTEM

CONTROL OF SHIFT VALVES A AND B
Pilot pressure generated by the operation of shift solenoid valves A and B is applied to the end face of shift
valves A and B.
The figure above shows the operation of shift valve B. When the shift solenoid valve is “ON”, pilot pressure
applied to the end face of the shift valve overcomes spring force, moving the valve upward.
Lock-up ControlBCS000ZU
The torque converter clutch piston in the torque converter is locked to eliminate torque converter slip to
increase power transmission efficiency. The solenoid valve is controlled by an ON-OFF duty signal sent from
the TCM. The signal is converted to an oil pressure signal which controls the torque converter clutch piston.
CONDITIONS FOR LOCK-UP OPERATION
When vehicle is driven in 3rd and 4th gear position, vehicle speed and throttle opening are detected. If the
detected values fall within the lock-up zone memorized in the TCM, lock-up is performed.

Removal and InstallationBBS004X6
CAUTION:

When removing water pump assembly, be careful not to get engine coolant on drive belts.

Water pump cannot be disassembled and should be replaced as a unit.

After installing water pump, connect hose and clamp securely, then check for leaks using radiator
cap tester (commercial service tool) and radiator cap tester adapter [SST: EG17650301].
REMOVAL
1. Remove engine cover. Refer to EM-133, "INTAKE MANIFOLD COLLECTOR" .
2. Remove air duct (inlet). Refer to EM-131, "
AIR CLEANER AND AIR DUCT" .
3. Remove undercover and splash guard (RH).
4. Drain engine coolant from radiator. Refer to CO-34, "
Changing Engine Coolant" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
5. Remove drive belts. Refer to EM-128, "
DRIVE BELTS" .
6. Remove reservoir tank of radiator. Refer to CO-37, "
RADIATOR" .
7. Remove reservoir tank of power steering oil pump with piping connected, and move it to aside.
8. Support oil pan (lower) bottom with transmission jack.
9. Remove engine mounting insulator (RH) and engine mounting bracket (RH). Refer to EM-223, "
