Torque converter and shaft
The torque converter consists of an impeller(pump), turbine and stator assembly in a single unit. The pump is
connected to the engine crankshaft and turns as the engine turns. This drawing force is transmitted to the turbine
through the oil which is recycled by the stator.
The transmission has two parallel shafts ; the input shaft and the output shaft. Both shafts are in line with the engine
crankshaft. The input shaft includes the overdrive clutch, reverse clutch, underdrive clutch, one way clutch, 2ND brake,
low&reverse brake, overdrive planetary carrier, output planetary carrier and transfer drive gear. The output shaft
includes the transfer driven gear.
CLUTCHES
The gear changing mechanism utilizes three multi- disc clutches. The retainers of these clutches are fabricated from
high- precision sheet metal for lightness and ease of production. Also, more responsive gearshifts at high engine
speeds are achieved by a pressure- balanced piston mechanism that cancels out centrifugal hydraulic pressure. This
mechanism replaces the conventional ball check valve.
UNDERDRIVE CLUTCH
The underdrive clutch operates in 1st, 2nd, and 3rd gears and transmits driving force from the input shaft to the
underdrive sun gear(A).
The components comprising the under clutch are as illustrated below.

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.

REPLACEMENT
If you have a fluid changer, use this changer to replace the fluid. If you do not, replace it using the following
procedure.1. Disconnect the hose which connects the transmission and the oil cooler which is within the radiator only in 2.4L
engine(3.3L- the oil cooler is separated).
2. Start the engine and let the fluid drain out.
Running conditions : "N" range with engine idling.
The engine should be stopped within one minute after it is started. If the fluid has all drained out before then,
the engine should be stopped at that point.
3. Romove the drain plug(A) from the bottom of the transmission case to drain the fluid.
4.Install the drain plug via the gasket, and tighten it to the specified torque.
TORQUE :
40~50Nm (4.0~5.0 kgf.m, 29~36 lb - ft)
5. Pour the new fluid in through the oil filler tube.
Stop pouring if the full volume of fluid cannot be poured in.
6. Repeat the procedure in step (2).
Check the old fluid for contamination. If it has been contaminated, repeat the steps (5) and (6).
7. Pour the new fluid in through the oil filler tube.
8. Reconnect the hose which was disconnected in step (1) above and firmly replace the oil level gauge.(In case of
this "replace", this means after wiping off any dirt around the oil level gauge, insert it into the filler tube.)
9. Start the engine and run it at idle for 1~2 minutes.
10. Move the select lever through all positions, and then move it to the "N" position.
11. Drive the vehicle until the fluid temperature rises to the normal temperature (70~80°C), and then check the fluid
level again. The fluid level must be at the HOT mark.
12. Firmly insert the oil level gauge(A) into the oil filler tube.
