9. TIGHTEN BOLTS IN UPPER FRONT AND REAR VALVE BODIES

Recheck the alignment of the gaskets. Tighten the bolts. Torque: 55 kg-cm (48 in.-lb, 5.4 N-m)

10. TURN ASSEMBLY OVER AND TIGHTEN BOLTS IN LOWER VALVE BODY

Tighten the bolts.

INSPECTION OF SPEEDOMETER GEAR AND EXTENSION HOUSING

1. IF NECESSARY. REPLACE SPEEDOMETER GEAR OIL SEAL

(a) Using SST, remove the oil seal. SST 09921-00010

<b) Using SST, install the new oil seal. SST 09201-60011

2. IF NECESSARY. REPLACE OIL SEAL AND DUST SEAL

(a) Using SST. remove the oil seal. SST 09308-10010

(b) Using SST. drive in a new oil seal and dust seal. SST 09325-20010

Torque Converter And Valve Housing

Torque Converter CLEAN TORQUE CONVERTER

If the transmission is contaminated, the torque converter and transmission cooler should be thoroughly flushed, using Toyota Transmission Cleaner.

INSPECTION OF TORQUE CONVERTER

1. INSERT SST IN END OF TORQUE CONVERTER

(a) Insert a turning tool in the inner race of the one-way clutch.

(b) Install the stopper so that it fits in the notch of the converter hub and other race of the one-way clutch.

2. TEST ONE-WAY CLUTCH

The clutch should lock when turned counterclockwise, and should rotate freely and smoothly clockwise. Less than 25 kg-cm (22 in.-lb, 2.5 N-m} of torque should be required to rotate the clutch clockwise. If necessary, clean the converter and retest the clutch. Replace the converter if the clutch still fails the test.

Electrical Parts

1. INSPECT SOLENOID

Check the resistance between the terminal and body. Standard resistance: 11 — 15 0

INSPECT NEUTRAL START SWITCH

Using an ohmmeter, check the continuity of the terminals for each switch position shown in the table below.

If continuity between the terminals is not as specified, replace the switch.

Magnetic Speed Sensor Testing

3. INSPECT SPEED SENSOR

Connect on ohmmeter to the speed sensor and check that the meter deflects when the sensor is repeatedly brought close to the rotor sensor magnet and removed from it.

ASSEMBLY OF TRANSMISSION

Disassembly, inspection and assembly of each component group have been indicated in the preceding chapter. This chapter deals with assembly of A43DE transmission.

GENERAL ASSEMBLY NOTE:

1. The automatic transmission is composed of highly precision-finished parts, necessitating careful inspection before assembly because even a small nick could cause fluid leakage or affect performance.

3. Before assembling new clutch discs, soak them in automatic transmission fluid for at least two hours.

5. Apply automatic transmission fluid on sliding or rotating surfaces of the parts before assembly.

7. Use petroleum jelly to keep the small parts in their places.

Before assembly, make sure again that all component groups are assembled correctly. If something wrong is found in a certain component group during assembly, inspect and repair this group immediately.

2. Do not use adhesive cements on gaskets and similar parts.

4. When assembling the transmission, be sure to use new gaskets and O-rings.

6. Dry all parts by blowing with compressed air. Never use shop rags.

8. Be sure to install the thrust bearings and races in the correct direction and position.
