Inspection

INSPECTION

PROCEDURE

1. INSPECT SOLENOID (SL) VALVE

(a) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection Condition Specified Condition Solenoid (SL) valve connector terminal - Solenoid (SL) valve body 20°C (68°F) 11 to 15 Ω If the result is not as specified, replace the solenoid (SL) valve.

*a Component without harness connected (Solenoid (SL) Valve)

(b) Connect a positive (+) lead from the battery to the terminal of the solenoid (SL) valve connector and a negative (-) lead to the solenoid (SL) valve body, and check that the solenoid (SL) valve moves and makes an operating sound.

NOTICE:

When using battery voltage during the inspection, do not bring the positive (+) and negative (-) tester probes too close to each other as a short circuit may occur.

OK:

The solenoid (SL) valve moves and makes an operating sound.

If the result is not as specified, replace the solenoid (SL) valve.

2. INSPECT SOLENOID (SLT) VALVE

(a) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 5.0 to 5.6 Ω If the result is not as specified, replace the solenoid (SLT) valve.

*a Component without harness connected (Solenoid (SLT) Valve)

(b) Connect a positive (+) lead from the battery with a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid (SLT) valve connector, and check that the solenoid (SLT) valve moves and makes an operating sound.

NOTICE:

When using battery voltage during the inspection, do not bring the positive (+) and negative (-) tester probes too close to each other as a short circuit may occur.

OK:

The solenoid (SLT) valve moves and makes an operating sound.

If the result is not as specified, replace the solenoid (SLT) valve.

Installation

INSTALLATION

PROCEDURE

1. INSTALL TRANSMISSION VALVE BODY ASSEMBLY

(a) Coat 2 new transaxle case gaskets with Toyota Genuine ATF WS and install them to the automatic transaxle case sub-assembly.

(b) Coat a new transaxle case gasket with Toyota Genuine ATF WS and install it to the counter drive gear sub-assembly.

(c) Coat a new No. 1 front oil pump cover gasket with Toyota Genuine ATF WS and install it to the front oil pump assembly.

(d) Coat a new No. 2 front oil pump cover gasket with Toyota Genuine ATF WS and install it to the front oil pump assembly.

(e) Align the slit portion of the manual valve and the manual valve lever sub-assembly as shown in the illustration, and install the transmission valve body assembly to the automatic transaxle case sub-assembly with the 9 bolts. Torque: 10.8 N·m {110 kgf·cm, 8 ft·lbf} NOTICE: Be careful that the transmission revolution sensor (NC) wire is not pinched.

*1 Manual Valve *2 Manual Valve Lever Sub-assembly

(f) Engage the clamp to connect the transmission revolution sensor (NC) wire connector.

Do not let transmission revolution sensor (NC) wire ride up over this area.

NOTICE:

To prevent it from being pinched between the transmission valve body assembly and the transmission case side cover, do not let the transmission revolution sensor (NC) wire ride up over the area shown in the illustration.
