INSPECT TORQUE CONVERTER ASSEMBLY
Inspect the one-way clutch.
Press on the splines of the stator with a finger and rotate the stator. Check that the stator rotates smoothly when turned clockwise and rotates with difficulty when turned counterclockwise.
If necessary, clean the torque converter and recheck the one-way clutch.
Replace the torque converter if the one-way clutch still fails the inspection.

| *a | Sample showing maximum allowable amount of powder in ATF |
Inspect the torque converter assembly.
If any of the following problems are present, replace the torque converter assembly.
A metallic sound is emitted from the torque converter assembly during the stall test or when the shift lever is moved to N.
The one-way clutch turns smoothly or locks in both directions.
The amount of powder in the ATF is more than the sample shown in the illustration (refer to the sample).
Tech Tips
The sample shows approximately 0.025 liters (0.026 US qts, 0.022 Imp. qts) of ATF that was removed from a torque converter.
Replace the ATF in the torque converter.
Tech Tips
If the ATF is discolored or has a foul odor, stir the ATF in the torque converter before replacing the ATF.
Clean and check the oil cooler and oil pipe line.
Tech Tips
If the torque converter is inspected or the ATF is replaced, it is necessary to clean the oil cooler and oil pipe line.
Apply compressed air of 196 kPa (2.0 kgf/ cm2, 28 psi) into the inlet hose.
If a large amount of powder is found in the ATF, add new ATF using a bucket pump and clean the oil cooler and oil pipe line again.
If the ATF is cloudy, inspect the oil cooler.
| *a | Correct |
| *b | Incorrect |
| *c | Bottom is damaged |
Prevent deformation of the torque converter and damage to the oil pump gear.
Note
Make sure that all of the bolts are the same length and that the specified bolts are used.
Tech Tips
If there is any damage to the tip of a bolt for the torque converter or to the bottom of a bolt hole, replace the bolt and torque converter.
INSTALL TORQUE CONVERTER ASSEMBLY
Engage the splines of the input shaft and turbine runner.
Engage the splines of the stator shaft and the stator while turning the torque converter assembly.
Tech Tips
If the stator shaft splines are difficult to engage with the stator splines, move the torque converter back approximately 10 mm and engage the splines while rotating the torque converter.
Turn the torque converter assembly to insert the key of the oil pump drive gear into the groove of the torque converter assembly.
Clean the torque converter set bolt holes.
| *a | Engine Surface |
| *b | Drive Plate Surface |
Using a vernier caliper and straightedge, measure dimension A between the transaxle contact surface of the engine and the torque converter contact surface of the drive plate.
Note
Make sure to deduct the thickness of the straightedge.
Using a vernier caliper and straightedge, measure dimension B shown in the illustration and check that dimension B is more than dimension A, which was measured in the previous step.
| Standard |
|---|
| A + 1 mm (0.0394 in.) or more |
Note
Make sure to deduct the thickness of the straightedge.
If the automatic transaxle assembly is installed to the engine with the torque converter not sufficiently inserted, the torque converter may be damaged.

INSTALL AUTOMATIC TRANSAXLE ASSEMBLY
| *1 | Torque Converter Centerpiece |
| *2 | Crankshaft |
Apply clutch spline grease to the surface of the crankshaft that contacts the torque converter centerpiece.
| Clutch spline grease |
|---|
| Toyota Genuine Clutch Spline Grease or equivalent |
| Maximum grease amount |
|---|
| Approximately 1 g (0.0353 oz.) |
While keeping the engine and automatic transaxle assembly horizontal, align the knock pins with the holes in the automatic transaxle assembly and install the 9 bolts shown in the illustration.
| Bolt | Bolt Length | Torque |
|---|---|---|
| A | 55 mm (2.17 in.) | 64 N*m (653 kgf*cm, 47 ft.*lbf) |
| B | 50 mm (1.97 in.) | 46 N*m (469 kgf*cm, 34 ft.*lbf) |
| C | 32 mm (1.26 in.) | 44 N*m (449 kgf*cm, 32 ft.*lbf) |
| 33 mm (1.30 in.) | 43 N*m (438 kgf*cm, 32 ft.*lbf) |
Note
Confirm that the 2 knock pins are installed to the transaxle contact surface of the engine cylinder block before installing the automatic transaxle assembly.
Do not forcibly pry on the automatic transaxle assembly.
Check that the torque converter rotates.
