MAINTENANCE AND REPAIR
ON–VEHICLE SERVICE
TRANSAXLE FLUID LEVEL
CHECKING PROCEDURE
Notice : Check the fluid level when the transaxle tempera-
ture is 70°C~80°C (158°F~176°F).
Notice : During the fluid level check, the selector lever
must be in position P.
Notice : When adding fluid or making a complete fluid
change, always use ISU DEXRON III. Failure to use the
proper fluid will cause hose and seal damage and fluid
leaks.
1. Make sure the vehicle is level.
2. Shift into all range from ”P” to ”1” and return to ”P”
with engine idling.
3. Remove the transaxle fluid dipstick and check the
transaxle fluid level.
4. The correct fluid level must be between the HOT
MIN and the HOT MAX notches on the dipstick.
5. If the fluid level is below the MIN notch, add trans-
axle fluid through the fluid filler tube and check for
leaks in the transaxle.
6. If the fluid above the MAX notch, the transaxle is
overfilled. Drain some of the fluid through the fluid
pan drain plug. Check the transaxle fluid level.
FLUID DRAIN PROCEDURE
Draining Procedure
1. Raise and support the vehicle. Refer to ”Vehicle
Lifting Procedures,” Section 0B, General Informa-
tion.
2. Place a suitable fluid drainage container under the
transaxle.
3. Remove the fluid drain plug. allow the fluid to drain
completely.
4. Clean the drain plug threads.
5. Install the fluid drain plug.
Tighten
Torque the fluid drain plug to 17 NSm (13 Ib–ft).

DAEWOO V–121 BL4
Filling Procedure
1. Remove the drainage container and lower the ve-
hicle.
2. Add three–fourths of the recommended amount of
ISU DEXRON III.
3. Start the engine and allow it to reach normal oper-
ating temperature.
4. Shift the gear selector through all positions.
5. Check the fluid level and add fluid until the dipstick
indicates a safe level.
LOCATING FLUID LEAKS
General Method
1. Verify that the material leaking is transaxle fluid.
2. Thoroughly clean the suspected leak area.
3. Allow the transaxle to reach the normal operating
temperature of 176–194°F (80–90°C).
4. Park the vehicle over a clean paper or a clean card-
board.
5. Turn the engine OFF and look for fluid spots on the
paper.
6. Make the necessary repairs to correct that leak.
Powder Method
1. Thoroughly clean the suspected leak area.
2. Apply an aerosol type powder, such as foot powder,
to the suspected leak area.
3. Allow the transaxle to reach the normal operating
temperature of 176–194°F (80–90°C).
4. Turn the engine OFF.
5. Inspect the suspected leak area and trace the leak
path through the powder to find the source of the
leak.
6. Make the necessary repairs to correct the leak.
Once the leak point is found, the source of the leak must
be determined and repaired.
CASE PORSITY REPAIR
1. Determine the leak area. Refer to ”Locating Fluid
Leaks” in this section.
2. Clean the leak area with the solvent. Air dry.
CAUTION : Epoxy cement may cause skin irritations
and eye damage. Read and follow all information on
the container label as provided by the manufacturer.
3. Mix a sufficient amount of epoxy cement following
the manufacturer’s recommendations.
4. While the transaxle case is hot, apply epoxy ce-
ment with a clean, dry soldering acid brush.
5. Allow the epoxy cement to dry for 3 hours before
starting the engine.

FLUID COOLER FLUSHING
Flushing Procedure
1. Drain the fluid from the transaxle and refill the
transaxle with new transaxle fluid. Refer to ”Fluid
Drain Procedure” in this section.
2. Let the engine idle for 5 minutes.
3. Drain the fluid from the transaxle and refill the
transaxle with new transaxle fluid. Refer to ”Fluid
Drain Procedure” in this section.
CONTROL CABLE ADJUSTMENT
Adjustment Procedure
The various shift control cable positions must match at the
shift control lever in the vehicle and at the selector lever
on the transaxle to provide proper transaxle shifting.
Place the shift control lever in the PARK position and
check the selector lever connection to verify that it is in the
forward most position. If it is not, the following adjustment
must be performed:
1. Disconnect the negative battery cable.
2. Remove the floor console. Refer to Section 9G,
Interior Trim.
3. Place the shift control lever in the PARK position.
4. Loosen the control cable adjusting nut.
5. Move the Transmission Range (TR) switch lever
counterclockwise until stopping the lever.
