If the level is at the low side, add new fluid.
Fluid type: ATF DEXRON®II
NOTICE:
Do not overfill.
(b) Check the fluid condition.
If the fluid smells burnt or is black, replace it.
(c) Replace the ATF.
(1) Remove the drain plug and drain the fluid.
(2) Reinstall the drain plug securely.
(3) With the engine OFF, add new fluid through the oil
filler pipe.
Fluid type: ATF DEXRON®II
Capacity:
A340E: 1.6 liters (1.7 US qts, 1.4 Imp. qts)
A340F: 2.0 liters (2.1 US qts, 1.8 Imp. qts)
(4) Start the engine and shift the shift lever into all posi-
tions from P to L position and then shift into P posi-
tion.
(5) With the engine idling, check the fluid level. Add
fluid up to the COOL level on the dipstick.
(6) Check the fluid level at the normal operating tem-
perature, 70 − 80°C (158 − 176°F), and add as nec-
essary.
NOTICE:
Do not overfill.
(d) Check the fluid leaks.
Check for leaks in the transmission.
If there are leaks, it is necessary to repair or replace O−
rings, FIPGs, oil seals, plugs or other parts.
(e) INSPECT AND ADJUST THROTTLE CABLE
(1) Check that the accelerator pedal is fully released.
(2) Check that the inner cable is not slack.
(3) Measure the distance between the outer cable end
and stopper on the cable.
Standard distance: 0 − 1 mm (0 − 0.04 in.)
If the distance is not standard, adjust the cable by the adjusting
nuts.
(f) Inspect and adjust the shift lever position.
When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator is not aligned with the correct position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures.
(1) Remove the nut on the No.1 gear shifting rod.
(2) Push the No.1 gear shifting rod fully downward.

7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation fluid temperature 50 − 80°C (122 − 176°F).
The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
Be careful to prevent SST’s hose from interfering with the exhaust pipe.
(1) Warm up the fluid.
(2) Remove the test plug on the transmission case right side and connect SST.
(See page AT−26 and AT−33 for the location to connect SST)
SST 09992−00094 (09992−00150, 09992−00270)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Start the engine and check idling speed.
(5) Keep your left foot pressed firmly on the brake pedal and shift into D position.
(6) Measure the line pressure when the engine is idling.
(7) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
NOTICE:
Release the accelerator pedal and stop test if the rear wheels begin to rotate before the engine speed
reaches specified stall speed.
(8) In the same manner, do the test in R position.

DTC P0750, P0755 Shift Solenoid A/B Malfunction (Shift
Solenoid Valve No.1/No.2)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd or O/D
gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical
trouble of the shift solenoid valves and valve body.
DTC No.DTC Detecting ConditionTrouble Area
P0750
P0755During normal driving, gear required by ECM does not match
actual gear
(2 trip detection logic)Shift solenoid valve No.1/No.2 is stuck open or closed
Valve body is blocked up or stuck
HINT:
Check the shift solenoid valve No.1 when DTC P0750 is output and check shift solenoid valve No.2 when
DTC P0755 is output.
INSPECTION PROCEDURE
1 Check shift solenoid valve No.1 or No.2 operation.
PREPARATION:
(a) Remove the oil pan.
(b) Remove the shift solenoid valve No.1 or No.2.
CHECK:
(a) Applying 490 kPa (5 kgf/cm2, 71 psi) of compressed air,
check that the solenoid valve does not leak air.
(b) When battery positive voltage is supplied to the shift sole-
noid valve, check that the solenoid valve opens.
NG Replace shift solenoid valve No.1 or No.2.
OK
2 Check valve body (See page DI−282).
NG Repair or replace valve body.
OK
Repair or replace transmission (See page
AT−26, AT−33).
