U241E AUTOMATIC TRANSAXLE – UNDERDRIVE CLUTCHAX–249
AX
4. INSPECT UNDERDRIVE CLUTCH DRUM SUB-
ASSEMBLY
(a) Using a caliper gauge, measure the inside diameter
of the underdrive clutch drum bush.
Standard drum bush:
32.56 to 32.58 mm (1.2818 to 1.2826 in.)
Maximum drum bush:
32.63 mm (1.2846 in.)
If the inside diameter is greater than the maximum,
replace the underdrive clutch drum sub-assembly.
REASSEMBLY
1. INSTALL UNDERDRIVE CLUTCH DRUM O-RING
(a) Coat a new O-ring with ATF and install it to the
underdrive clutch drum.
2. INSTALL UNDERDRIVE CLUTCH PISTON SET
(a) Coat the underdrive clutch piston with ATF, and
install it to the underdrive clutch piston drum.
NOTICE:
Be careful not to damage the O-ring.
(b) Install the piston return spring and clutch balancer to
the underdrive clutch drum.
NOTICE:
Be careful not to damage the lip seal of the
clutch balancer.
(c) Place SST on the clutch balancer and compress the
piston return spring with a press.
SST 09350-32014 (09351-32070)
(d) Using a snap ring expander, install the snap ring to
underdrive clutch drum.
NOTICE:
• Be sure the end gap of the snap ring is not
aligned with the clutch balancer's claw.
• Stop the press when the spring sheet is
lowered to the place 1 to 2 mm (0.039 to 0.078
in.) from the sap ring groove.

ROAD TEST
1. PROBLEM SYMPTOM CONFIRMATION
(a) Based on the result of the customer problem
analysis, try to reproduce the symptoms. If the
problem is that the transaxle does not shift up, shift
down, or the shift point is too high or too low,
conduct the following road test referring to the
automatic shift schedule and simulate the problem
symptoms.
2. ROAD TEST
NOTICE:
Perform the test at the normal operating ATF
temperature of 50 to 80
C (122 to 176F).
(a) D position test
Move the shift lever to D and fully depress the
accelerator pedal. Check the following:
(1) Check up-shift operation.
Check that the 1
2, 2 3 and 3 O/D up-
shifts take place at the shift point shown in the
automatic shift schedule (see page SS-55).
HINT:
O/D Gear Up-shift Prohibition Control
• Engine coolant temperature is 55
C (131F)
or less and vehicle speed is at 70 km/h (43
mph) or less.
• ATF temperature is 5
C (41F) or less.
O/D Gear Lock-up Prohibition Control
• Brake pedal is depressed.
• Accelerator pedal is released.
• Engine coolant temperature is 60
C (140F)
or less.
(2) Check for shift shock and slip.
Check for shock and slip at the 1
2, 2 3 and
3
O/D up-shifts.
(3) Check for abnormal noise and vibration.
Check for abnormal noise and vibration when
up-shifting from 1
2, 2 3 and 3 O/D while
driving with the shift lever on D, and check while
driving in the lock-up condition.
HINT:
The check for the cause of abnormal noise and
vibration must be done thoroughly as it could
also be due to loss of balance in the differential,
torque converter clutch, etc.
(4) Check kick-down operation.
While driving the vehicle in the 2nd, 3rd and O/D
gears with the shift lever on D, check that the
possible kick-down vehicle speed limits for 2
1, 3
2 and O/D 3 kick-downs conform to
those indicated in the automatic shift schedule
(see page SS-55).
(5) Check for abnormal shock and slip at kick-down.

MECHANICAL SYSTEM TESTS
1. STALL SPEED TEST
HINT:
This test is to check the overall performance of the
engine and transaxle.
NOTICE:
• Do not perform the stall speed test longer than 5
seconds.
• To ensure safety, perform this test in an open and
level area that provides good traction.
• The stall speed test should always be performed
with at least 2 people. One person should observe
the condition of the wheels and wheel chocks
while the other is performing the test.
(a) Connect the intelligent tester to the CAN VIM. Then
connect the CAN VIM to the DLC3.
(b) Run the vehicle until the transmission fluid
temperature has reached 50 to 80
C (122 to 176F).
(c) Allow the engine to idle with the air conditioning
OFF.
(d) Chock all 4 wheels.
(e) Set the parking brake and keep the brake pedal
depressed firmly with your left foot.
(f) Move the shift lever to the D position.
(g) Depress the accelerator pedal as much as possible
with your right foot.
(h) Read the engine rpm (stall speed) and release the
accelerator pedal immediately.
Standard value:
2,150 to 2,450 rpm
Evaluation:
NOTICE:
Perform the test at the normal operating ATF
temperature of 50 to 80
C (122 to 176F).
2. SHIFT TIME LAG TEST
HINT:
This test is to check the condition of the direct clutch,
forward clutch, 1st brake and reverse brake.
(a) Connect the intelligent tester to the CAN VIM. Then
connect the CAN VIM to the DLC3.
(b) Run the vehicle until the transmission fluid
temperature has reached 50 to 80
C (122 to 176F).
(c) Allow the engine to idle with the air conditioning
OFF.
Test Result Possible Cause
Stall speed is lower than standard value • Stator one-way clutch is not operating properly
• Torque converter is faulty (stall speed is less than standard value
by 600 rpm or more)
• Engine power may be insufficient
Stall speed is higher than standard value • Line pressure is low
• C1 clutch slipping
• F3 one-way clutch is not operating properly
• F4 one-way clutch is not operating properly
