Toyota Sienna Service Manual: Removal
1. Remove engine under cover no.1 2. Disconnect cable from negative battery terminal 3. Drain automatic transaxle fluid (see page ax-131) 4. Remove automatic transaxle oil pan subassembly
(a) Remove the 18 bolts, oil pan and gasket.
| NOTICE: Some fluid will remain in the oil pan. Carefully remove the oil pan so that the fluid remaining in the pan does not spill out. |
(b) Remove the 2 magnets from the oil pan.
(c) Examine particles in the pan.
(1) Collect any steel chips using the removed magnets. Look carefully at the chips and particles in the pan and on the magnets to see the type of wear which might be found in the transaxle.
Result: Steel (magnetic): Wear of the bearing, gear or plate Brass (non-magnetic): Wear of the bearing
5. DISCONNECT TRANSMISSION WIRE
(a) Disconnect the 7 shift solenoid valve connectors.
(b) Remove the bolt and lock plate, and disconnect the ATF temperature sensor.
6. REMOVE VALVE BODY OIL STRAINER ASSEMBLY
(a) Remove the 3 bolts and oil strainer.
| NOTICE: Be careful when removing the oil strainer as fluid will come out. |
(b) Remove the O-ring from the valve body oil strainer assembly.
7. REMOVE TRANSMISSION VALVE BODY ASSEMBLY
(a) Support the valve body assembly and remove the 17 bolts and the transmission valve body assembly.
(b) Remove the check ball body and the spring.
(c) Remove the bolt and lock plate from the valve body assembly.
(d) Remove the shift solenoid valve SL3 and SLT from the valve body assembly.
(e) Remove the bolt and shift solenoid valve S4 from the valve body assembly
(f) Remove the shift solenoid valve SR from the valve body assembly.
(g) Remove the bolt and shift solenoid valve DSL from the valve body assembly.
(h) Remove the bolt and shift solenoid valve SL2 from the valve body assembly.
(i) Remove the bolt and shift solenoid valve SL1 from the valve body assembly.

Starter Relay Circuit High
MONITOR DESCRIPTION
While the engine is being cranked, the positive battery voltage is applied to
terminal STA of the ECM.
If the ECM detects the Starter Control (STA) signal while the vehicle is being
driven, it determines that
there is a malfunction in the STA circuit. The ECM then il ...
Air Mix Damper Control Servo Motor Circuit (Passenger Side)
DESCRIPTION
The air mix control servo motor (air mix damper servo sub-assembly) is
controlled by the A/C amplifier.
The air mix control servo motor moves the air mix damper by rotating (normal,
reverse) with electrical
power from the A/C amplifier.
This adjusts the mix ratio of the air t ...
Air Outlet Damper Control Servo Motor Circuit
DESCRIPTION
This circuit turns the servo motor and changes each damper position by
receiving the signals from the A/
C amplifier.
The air outlet damper servo motor switches the air outlet mode by rotating
(normal, reverse) with electrical
power from the A/C amplifier.
When the AUTO swit ...
