TROUBLE DIAGNOSIS
6. Accelerate to wide open throttle gradually while applying footbrake.
7. Quickly note the engine stall revolution and immediately release throttle.
CAUTION:
Do not hold down the accelerator pedal for more than 5 sec-
onds during this test.
8. Move selector lever to “N” position.
9. Cool off ATF. CAUTION:
Run the engine at idle for at least 1 minute.
10. Repeat steps 6 through 9 with selector lever in “2”, “1” and “R” positions.
Judgement of Stall Test
The test result and possible damaged components relating to each result are shown in the illustrations on next
page.
In order to pinpoint the possible damaged components, refer to AT-43, "
How to Perform Trouble Diagnosis for
Quick and Accurate Repair".
NOTE:
Stall revolution is too high in “D”, “2”, or “1” position:
• Slippage occurs in 1GR but not in 2GR and 3GR. ..... Low one-way clutch slippage
• Slippage occurs in the following gears:
1GR through 3GR in “D” position and engine brake functions with OD OFF. (OD OFF indicator lamp is on.)
1GR and 2GR in “2” position and engine brake functions with accelerator pedal released (fully closed throt-
tle)...... Forward clutch or forward one-way clutch slippage
Stall revolution is too high in “R” position:
• Engine brake does not function in “1” posit ion. ..... Low & reverse brake slippage
• Engine brake functions in “1” position. ..... Reverse clutch slippage
Stall revolution within specifications:
• Vehicle does not achieve speed of more than 80 km/h ( 50 MPH). ..... One-way clutch seizure in torque con-
verter housing
CAUTION:
Be careful because automatic flui d temperature increases abnormally:
• Slippage occurs in 3GR and 4GR in “D” position. ..... High clutch slippage
• Slippage occurs in 2GR and 4GR in “D” position. ..... Brake band slippage
• Engine brake does not function in 2GR and 3GR in “D” pos ition, 2GR in “2” position, and 1GR in “1” position
with OD OFF. (OD OFF indicator lamp is on.) ..... Overrun clutch slippage
Stall revolution less than specifications:
• Poor acceleration during starts. ..... One-way clutch seizure in torque converter Stall revolution:

REPAIR FOR COMPONENT PARTS
• Measure side clearance of inner gear and outer gear in at leastfour places around each outside edge. Clearances measured val-
ues should be within the specified clearance.
• If clearance is less than standard, select inner gear and outer gear as a set so that clearance is within specifications. Refer to “Parts
Information” for the inner gear and outer gear selection.
• If clearance is more than standard, replace whole oil pump assem- bly except oil pump cover.
• Measure clearance between outer gear and oil pump housing.
• If not within allowable limit, replace whole oil pump assembly except oil pump cover.
Seal Ring Clearance
• Measure clearance between seal ring and ring groove.
• If not within allowable limit, replace oil pump cover assembly.

b. Install needle bearing on bearing retainer.CAUTION:
Be careful to direction of needle bearing.
c. Install output shaft on transaxle case.
d. Measure dimensions (
1) and (2) at side cover and then cal-
culate dimension (A).
• Measure dimension ( 1) and ( 2) in at least two places.
e. Measure dimensions (
2) and (3) and then calculate dimen-
sion (B).
• Measure dimension ( 2)and ( 3) in at least two places.
f. Select proper thickness of output shaft adjusting shim so that output shaft end play (clearance between side cover and output
shaft bearing) is within specifications. Refer to “Parts Informa-
tion” for output shaft adjusting shim selection.
g. Install output shaft adjusting shim on output shaft bearing.

Adjustment (2)INFOID:0000000005397453
When any parts listed below are replaced, adjust total end play and reverse clutch end play.
TOTAL END PLAY
• Measure clearance between reverse clutch drum and needle bear-
ing for oil pump cover.
• Select proper thickness of bearing race so that end play is within specifications.
1. Measure dimensions (K) and (L ), and then calculate dimension
(J).
