TORQUE CONVERTER STALL TEST
This test measures the maximum engine speed when the selector lever is in the D or R position. The torque converter
stalls to test the operation of the torque converter, starter motor, one- way clutch operation, the holding performance of
the clutches, and brakes in the transaxle.
Do not let anybody stand in front of or behind the vehicle while this test is being carried out
1. Check the automatic transmission fluid level and temperature, and the engine coolant temperature.
a. Fluid level : At the HOT mark on the oil level gauge
b. Fluid temperature : 80~100°C (176~212°F)
c. Engine coolant temperature : 80~100°C(176~212°F)
2. Prevent all the wheels from moving during the test.
3. Pull the parking brake lever up, with the brake pedal fully depressed.
4. Start the engine.
5.Move the selector lever to the "D" position, fully depress the accelerator pedal and take a reading of the maximum
engine speed at this time.
Stall speed : 2,100~2,900rpm
a.The throttle should not be left fully open for any more than five seconds.
b. If carrying out the stall test two or more times, move the selector lever to the "N" position and run the
engine at 1,000 r/min to let the automatic transaxle fluid cool down before carrying out subsequent tests.
6. Move the selector lever to the "R" position and carry out the same test again.
TORQUE CONVERTER STALL TEST CONCLUSION
1.Stall speed is too high in both "D" and "R" ranges
a. Low line pressure
b. Low & reverse brake(B) slippage
2. Stall speed is to high in "D" range only
a. Underdrive clutch(C) slippage
3. Stall speed is too high in "R" range only
a. Reverse clutch(A) slippage
4. Stall speed too low in both "D" and "R" ranges
a. Malfunction of torque converter(D)
b. Insufficient engine output
HYDRAULIC PRESSURE TEST
1.Warm up the engine until the automatic transaxle fluid temperature is 80- 100°C.
2. Lift up the vehicle so that the wheels are free to turn.
3. Connect the special tool (oil pressure gauge) to each pressure discharge port.
4. Measure the hydraulic pressure at each port under the conditions given in the standard hydraulic pressure table,
and check that the measured values are within the standard value ranges.
5. If a value is outside the standard range, correct the problem while referring to the hydraulic pressure test diagnosis
table.

SERVICE ADJUSTMENT PROCEDURE
Automatic transaxle fluid
INSPECTION 1. Drive the vehicle until the fluid reaches normal operating temperature [70~80°C].
2. Place the vehicle on a level surface.
3. Move the selector lever through all gear positions. This will fill the torque converter and the hudraulic system with
fluid and move the selector lever to the "N" (Neutral) or "P"(Park) position.
4. Before removing the oil level gauge, wipe all contaminants from around the oil level gauge. Then take out the oil
level gauge and check the condition of the fluid.
If the fluid smells as if it is burning, it means that the fluid has been contaminated by fine particles from the
bushes and friction materials, a transaxle overhaul may be necessary.
5. Check that the fluid level is at the HOT mark on the oil level gauge. If the fluid level is low, add automatic transaxle
fluid until the level reaches the "HOT" mark.
Auto transaxle fluid:
DIAMOND ATF SP - III, SK ATF SP - III
Quantity : 8.5ℓ (9.0 US qt, 7.5 lmp.qt)
Low fluid level can cause a variety of a abnormal conditions because it allows the pump to take in air along
with fluid. Air trapped in the hydraulic system forms bubbles, which are compressable. Therefore, pressures
will be erratic, causing delayed shifting ,slipping clutches and brakes, etc. Improper filling can also raise fluid
level too high. When the transaxle has too much fluid, gears churn up foam and acuise the same conditions
which occur with low fluid level, resulting in accelerated deterioration of automatic transaxle fluid. In either
case, air bubbles can cause overheating, and fluid oxidation, which can interfere with normal valve, clutch, and
brake operation. Foaming can also result in fluid escaping from the transaxle vent where it may be mistaken
for a leak.
6. Insert the oil level gauge(A) securely.
When new, automatic transmission fluid should be red. The red dye is added so the assembly plant can
identify it as transmission fluid and distinguish it from engine oil or antifreeze. The red dye, which is not an
indicator of fluid quality, is not permanent. As the vehicle is driven the transmission fluid will begin to look
darker. The color may eventually appear light brown.

Noise Hissing Noise in Steering Gear
There is some noise with all power steering systems. One of the most common is a hissing
sound when the steering wheel is turned and the car is not moving. This noise will be most
evident when turning the wheel while the brakes are being applied. There is no relationship
between this noise and steering performance. Do not replace the valve unless the "hissing"
noise becomes extreme. A replaced valve will also make a slight noise, and is not always a
solution for the condition.
