PRECAUTIONS
• Be sure to turn the ignition switch OFF and disconnect battery negative cable from battery negative
terminal before any repair or inspection work. The open/short circuit of related switches, sensors,
solenoid valves, etc. will cause the MIL to light up.
• Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connectors are free from water, grease,
dirt, bent terminals, etc.)
• Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
• Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
PrecautionINFOID:0000000001703154
•Before connecting or disconnecting the TCM harness connec-
tor, turn ignition switch OFF and disconnect the battery cable
from the negative terminal. Failure to do so may damage the
TCM. Because battery voltage is applied to TCM even if igni-
tion switch is turned off.
•When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM pin
terminal, when connecting pin connectors.
•Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly or
not. (See page AT-71, "
TCM Terminal and Reference Value".)
•After performing each TROUBLE DIAGNOSIS, perform “DTC
(Diagnostic Trouble Code) Confirmation Procedure”.
The DTC should not be displayed in the “DTC Confirmation
Procedure” if the repair is completed.
• Before proceeding with disassembly, thoroughly clean the outside
of the transaxle. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
• Disassembly should be done in a clean work area.
• Use lint-free cloth or towels for wiping parts clean. Common shop
rags can leave fibers that could interfere with the operation of the A/T.
• Place disassembled parts in order for easier and proper assembly.
• All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
• Gaskets, seals and O-rings should be replaced any time the A/T is disassembled.
• It is very important to perform functional tests whenever they are indicated.
• The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent springs
and small parts from becoming scattered or lost.
• Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.

6. Accelerate to wide open throttle gradually while applying foot
brake.
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-40, "
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 1st gear but not in 2nd and 3rd gears. ..... Low one-way clutch slippage
• Slippage occurs in the following gears:
1st through 3rd gears in “D” position and engine brake functions with OD OFF. (OD OFF indicator lamp is
on.)
1st and 2nd gears in “2” position and engine brake functions with accelerator pedal released (fully closed
throttle)...... Forward clutch or forward one-way clutch slippage
Stall revolution is too high in “R” position:
• Engine brake does not function in “1” position. ..... 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 fluid temperature increases abnormally:
• Slippage occurs in 3rd and 4th gears in “D” position. ..... High clutch slippage
• Slippage occurs in 2nd and 4th gears in “D” position. ..... Brake band slippage
• Engine brake does not function in 2nd and 3rd gears in “D” position, 2nd gear in “2” position, and 1st gear 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: 2,310 - 2,770 rpm
