MAINTENANCE AND REPAIR
ON–VEHICLE SERVICE
TRANSAXLE FLUID LEVEL
CHECKING PROCEDURE
Tools Required
DW260–070 Plug Remover/Installer
Inspection Procedure
1. Start the engine and allow the engine to idle for
approximately 5 minutes, or, if possible, drive the
vehicle for a few kilometers(miles) to warm the
transaxle fluid. Check the fluid level when the trans-
axle is over 30°C(86°F).
2. Press the brake pedal and move the shift lever
through the gear ranges, pausing a few seconds in
each range. Return the shift lever to the park posi-
tion. (Left–Hand Drive Shown, Right–Hand Drive
Similar.)
3. Raise and suitably support the vehicle.
4. Place a fluid container below the fluid level plug.
CAUTION : Do not remove the fluid level plug if the
transaxle fluid is hot. This may cause injury if the fluid
drains from the plug hole.
5. Remove the fluid level plug using the plug remover/
installer DW260–070. Because the transaxle oper-
ates correctly over a range of levels, fluid may or
may not drain out of the plug hole when the plug is
removed.

5A1 – 192IZF 4 HP 16 AUTOMATIC TRANSAXLE
DAEWOO V–121 BL4
FLUID LEVEL SET AFTER SERVICE
1. Add transaxle fluid through the fill cap hole prior to
adjusting the fluid level. The amount of fluid to add
should be based on the type of service done.
Adjustment Notice
S Use ESSO LT 71141 transaxle fluid only.
S Oil pan removed : 4L (4.2 qt)
S Torque converter removed : 2L (2.1 qt)
S Complete overhaul : 6.7L (7.1qt)
S Drain plug removed : 4L (4.2 qt)
2. Check the transaxle fluid level. Refer to ”Transaxle
Fluid Level Checking Procedure” in this section.
3. Add additional fluid through the fill cap hole in 0.5
liter (0.5 quart) increments until the fluid comes out
through the plug hole.
4. Allow the fluid to finish draining out through the plug
hole, then install the fluid level plug.
5. When the fluid level setting procedure is completed,
wipe any fluid from the transaxle case with a rag or
shop towel. Also, check that the fluid fill cap and the
vent tube are properly installed.
REPAIRING FLUID LEAKS
Locating Leaks
General Method
1. Verify that the leak is transaxle fluid.
2. Thoroughly clean the suspected leak area.
3. Operate the vehicle for about 25 kilometers (15
miles) or until the transaxle reaches normal operat-
ing temperature, 88°C (190°F).
4. Park the vehicle over clean paper or cardboard.
5. Turn the engine off and look for fluid spots on the
paper.
6. Make the necessary repairs to correct the leak.
Powder Method
1. Thoroughly clean the suspected leak area.
2. Apply an aerosol–type powder (foot powder) to the
suspected leak area.
3. Operate the vehicle for about 25 kilometers (15
miles) or until the transaxle reaches normal operat-
ing temperature, 88°C (190°F).
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.

DAEWOO V–121 BL4
Repairing the Fluid Leak
The following are potential causes for fluid leaks. Check
and repair, as necessary.
S Fasteners are not tightened to specifications.
S Fastener threads and tapped holes are dirty or cor-
roded.
S Gaskets, seals or sleeves are misaligned, dam-
aged, or warped, or scratched.
S The manual shaft is nicked or damaged.
S There is a loose or worn bearing causing excess
seal or sleeve wear.
S Case or component porosity.
S The fluid level is too high.
S There is a plugged vent or a damaged vent tube.
S There is water or coolant in the fluid.
S Fluid drain back holes are plugged.
CASE POROSITY REPAIR
CAUTION : Epoxy adhesive may cause skin irritations
and eye damage. Read and follow all information on
the container label as provided by the manufacturer.
1. Thoroughly clean the area to be repaired with a
cleaning solvent. Air dry the area.
2. Using instructions from the manufacturer, mix a
sufficient amount of epoxy to make the repair.
3. While the transaxle case is still hot, apply the
epoxy. You can use a clean, dry soldering acid
brush to clean the area and also apply the epoxy
cement. Make certain that the area to be repaired is
fully covered.
4. Allow the epoxy cement to dry for 3 hours before
starting the engine.
5. Repeat the fluid leak diagnosis procedures. Refer
to ”Fluid Leak Diagnosis and Repair” in this sec-
tion.

SHIFT CONTROL CABLE
ADJUSTMENT
Adjustment Procedure
It is very important to match the shift control lever correctly
with the selector lever connection. Place the shift control
lever in the P position and check the selector lever connec-
tion to see if it is all the way forward. If it is not, proceed with
the following adjustment.
1. Remove the battery and battery tray. Refer to Sec-
tion 1E, Engine Electrical.
