Valve Body Assembly

VALVE BODY ASSEMBLY

COMPONENTS:

REMOVAL
1. REMOVE AUTOMATIC TRANSAXLE ASSEMBLY

2. REMOVE AUTOMATIC TRANSAXLE OIL PAN SUB-ASSEMBLY
(a) Remove the 18 bolts and oil pan from the transaxle.

NOTICE: Some fluid will remain in the oil pan. Remove all the pan bolts, and carefully remove the oil pan assembly.

(b) Remove the gasket from the oil pan.

(d) Examine particles in the oil pan.
(1) Collect any steel chips with the removed magnets. Look carefully at the chips and particles in the oil pan and on the magnets to see the type of wear which might be found in the transaxle.
Result:
Steel (magnetic): Bearing, gear and plate wear
Brass (non-magnetic): Bearing wear

3. REMOVE VALVE BODY OIL STRAINER ASSEMBLY
(a) Remove the 2 bolts and oil strainer from the valve body.

(b) Remove the O-ring from the oil strainer.

4. REMOVE TRANSMISSION VALVE BODY ASSEMBLY
(a) Remove the 11 bolts and valve body from the transaxle.

NOTICE: When removing the transmission valve body assembly, be careful not to allow the transmission revolution sensor and the transaxle case to interfere with each other.

5. REMOVE MANUAL VALVE
(a) Remove the manual valve from the valve body.

INSTALLATION

1. INSTALL MANUAL VALVE
(a) Coat the manual valve with ATF and install it to the valve body.

2. INSTALL TRANSMISSION VALVE BODY ASSEMBLY
(a) Coat the O-ring of the transmission wire with ATF.

(b) Confirm that the manual valve lever is positioned as shown in the illustration and install the valve body assembly to the transaxle case with the 11 bolts.
Torque: 11 N*m (112 kgf*cm, 8 ft.*lbf)
Bolt length:
Bolt A: 25 mm (0.98 in.)
Bolt B: 30 mm (1.18 in.)
Bolt C: 35 mm (1.38 in.)
Bolt D: 45 mm (1.77 in.)
Bolt E: 55 mm (2.17 in.)

NOTICE:
^ When installing the transmission valve body assembly, be careful not to allow the transmission revolution sensor and transaxle case to interfere with each other.
^ Be sure to insert the pin of the manual valve lever into the groove on the end of the manual valve.
^ First, temporarily tighten the bolts marked by (*1) in the illustration because they are positioning bolts.

3. INSTALL VALVE BODY OIL STRAINER ASSEMBLY
(a) Coat a new O-ring with ATF and install it to the oil strainer.

NOTICE: Ensure that the O-ring is not twisted or pinched.

(b) Install the oil strainer to the valve body with the 2 bolts.
Torque: 11 N*m (112 kgf*cm, 8 ft.*lbf)

4. INSTALL AUTOMATIC TRANSAXLE OIL PAN SUB-ASSEMBLY
(a) Install the 2 magnets to the oil pan.
(b) Install a new gasket to the oil pan.
(c) Apply adhesive to the 18 bolts.
Adhesive: Toyota Genuine Adhesive 1344, Three Bond 1344 or equivalent.

(d) Install the oil pan to the automatic transaxle with the 18 bolts.
Torque: 7.5 N*m (76 kgf*cm, 66 in.*lbf)

NOTICE:
^ In order to ensure proper sealing of the transmission oil pan bolts, apply sealant to the bolts and install them within 10 minutes of sealant application.
^ Completely remove any oil or grease from the contact surface of the transaxle case and oil pan sub-assembly with the gasket before installation.
