1998 OPEL FRONTERA engine coolant

7A–23 AUTOMATIC TRANSMISSION (4L30–E)
Stall Test
The stall test allows you to check the transmission for
internal abrasion and the one way clutch for slippage.
Torque converter performance can also be evaluated.
The stall test results together with the road test results will
identify transmission components requiring servicing or
adjustment.
Stall Test Procedure:
1. Check the level of the engine coolant, the engine oil,
and the automatic transmission fluid. Replenish if
necessary.
2. Block the wheels and set the parking brake.
3. Connect a tachometer to the engine.
4. Start the engine and allow it to idle until the engine
coolant temperature reaches 70 – 80
C (158 –
176
F).
5. Hold the brake pedal down as far as it will go.
6. Place the selector in the “D” range.
7. Gradually push the accelerator pedal to the floor.
The throttle valve will be fully open.
Note the engine speed at which the tachometer
needle stabilizes.
Stall Speed : 2,100
150 rpm
NOTE: Do not continuously run this test longer than 5
seconds.
8. Release the accelerator pedal.
9. Place the selector in the “N” range.
10. Run the engine at 1,200 rpm for one minute.
This will cool the transmission fluid.
11. Repeat Steps 7 – 10 for the “3”, “2”, “L” and “R”
ranges.
Line Pressure Test
The line pressure test checks oil pump and control valve
pressure regulator valve function. It will also detect oil
leakage.
Line Pressure Test Procedure:
1. Check the level of the engine coolant, the engine oil,
and the automatic transmission fluid.
Replenish if required.
2. Block the wheels and set the parking brake.
3. Remove the pressure detection plug at the left side of
the transmission case.
Set 5–8840–0004–0 pressure gauge and adapter to
the pressure detection plug hole.

4. Start the engine and allow it to idle until the engine
coolant temperature reaches 70 – 80
C (158 –
176
F).
5. Hold the brake pedal down as far as it will go.
6. Place the selector in the “D” range.
7. Note the pressure gauge reading with the engine
idling.
8. Gradually push the accelerator pedal to the floor. The
throttle valve will be fully open.
Note the pressure gauge reading with the accelerator
pedal fully depressed.
NOTE: Do not continuously run this test longer than 5
seconds.
9. Release the accelerator pedal.
10. Place the selector in the “N” range.
11. Run the engine at 1,200 rpm for one minute.
This will cool the transmission fluid.
12. Repeat Steps 7 – 11 for the “3”, “2”, “L”, and “R”
ranges.
13. Install a pressure detection plug to the transmission
case, applying recommended thread locking agent
(LOCTITE 242) or its equivalent to thread of plug.
Make sure that thread is cleaned before applying
locking agents.
14. Tighten the pressure detection plug to the specified
torque.
Torque:9–14Nꞏm(0.9–1.4kgꞏm/7–10lbft)

7A–56
AUTOMATIC TRANSMISSION (4L30–E)
56. Connect wiring harness harness assembly (52) to
converter clutch solenoid, force motor, and 5 pin
connector.
57. Install oil pan gasket, adapter case oil pan (53), and
twelve 10 mm screws.
Torque: 11 N
m (1.1 kgꞏm/96 lb in)
Rotate transmission, with bottom pan facing down.
58. Install mode switch (54), two 10 mm screws, selector
lever nut, and cover.
10 mm screw
Torque: 13 N
m (1.3 kgꞏm/113 lb in)
Nut
Torque: 23 N
m (2.3 kgꞏm/17 lb ft)
Adjust using setting tool, refer to Mode Switch in
this section.
59. Install O–ring (55) on turbine shaft.60. Install torque converter (56)
The converter assembly must be replaced under any
of the following conditions:
a. Evidence of damage to the pump assembly.
b. Metal particles are found after flushing the cooler
lines.
c. External leaks in hub weld area.
d. Converter pilot broken, damaged, or poor fit into
crankshaft.
e. Converter hub scored or damaged.
f. Internal failure in stator.
g. Contamination from engine coolant.
h. Excess end play.Rotate transmission, bell housing up. Spin
converter to insure proper fit.
61. Fill transmission through the overfill screw hole of oil
pan, using ATF DEXRON
–III. Refer to Changing
Transmission Fluid in this section.
