AUTOMATIC TRANSAXLE [GF4A-EL]
MECHANICAL SYSTEM TEST [GF4A-EL]
Mechanical System Test Preparation
1. Engage the parking brake and use wheel chocks
at the front and rear of the wheels.
2. Check the engine coolant. (Refer to 01-11
ENGINE OIL LEVEL INSPECTION.)
3. Check the engine oil. (Refer to 01-12 ENGINE
COOLANT LEVEL INSPECTION.)
4. Check the ATF levels. (Refer to 0 5 -1 7B
AUTOMATIC TRANSAXLE FLUID (ATF)
INSPECTION [GF4A-EL].)
5. Check the idle speed and ignition timing in P
position. (Refer to 01-1 OB ENGINE TUNE-UP
[KL].)
Line Pressure Test
Warning
•
Removing the square-head plug when the
ATF is hot can be dangerous. Hot ATF can
come out of the opening and badly burn.
Before removing the square-head plug,
allow the ATF to cool.
1. Remove the square head plug shown in the figure
2. Connect the SSTs (49 H019 002, 49 B019 901,
and 49 0378 400B) to the line pressure inspection
port.

3. Start the engine.
4. Shift the selector lever to D range and read the
line pressure at idle.
5. Replace the SST (49 B019 901) to the 49 B019

Caution
•
If the accelerator pedal is pressed for
longer than 5 seconds while the brake
pedal is depressed, the transaxle could be
damaged. Therefore, do steps 5 and 6
within 5 seconds of each other.
6. Firmly depress the brake pedal with the left foot,
and then gradually depress the accelerator pedal
with the right.
7. When the engine speed no longer increases,
quickly read the line pressure and release the
accelerator.
8. Shift the selector to N position and let the engine
idle for 1 minute or more to cool the ATF.
9. Read the line pressure at idle and at the engine
stall speed for the remaining ranges in the same
manner.
