The points shown in the rib sides and oil cooler near here
cannot be staked with SST. Use pliers or similar object
and be careful not to damage the core plates.
(b) Check the lock plate height (H) after completing the caulk-
ing.

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 and direct clutch 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, valve body or automatic transaxle (clutch, brake or gear etc.).
DTC No.DTC Detecting ConditionTrouble Area
P0750
P0755During normal driving, the gear required by the ECM does not
match the 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

Automatic transaxle (clutch, brake or gear etc.)
HINT:
Check the shift solenoid valve No.1 when DTC P0750 is output and check the 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 valve opens.
OK:
(a) Solenoid valve does not leak air.
(b) Solenoid valve opens.
NG Replace the shift solenoid valve No.1 or No.2.

DTC P0770 Shift Solenoid E Malfunction
(Shift Solenoid Valve SL)
SYSTEM DESCRIPTION
The ECM uses the signals from the throttle position sensor, air-
flow meter and crankshaft position sensor to monitor the en-
gagement condition of the lock-up clutch.
Then the ECM compares the engagement condition of the
lock-up clutch with the lock-up schedule in the ECM memory
to detect mechanical trouble of the shift solenoid valve SL,
valve body, torque converter clutch or automatic transaxle
(clutch, brake or gear etc.).
DTC No.DTC Detecting ConditionTrouble Area
P0770

Lock-up does not occur when driving in the lock-up range
(normal driving at 80 km/h [50 mph]), or lock-up remains ON
in the lock-up OFF range.
(2-trip detection logic)

When lock-up is ON, clutch or brake slips or gear is broken.
Shift solenoid valve SL is stuck open or closed

Valve body blocked up or stuck

Lock-up clutch

Automatic transaxle (clutch, brake or gear etc.)
INSPECTION PROCEDURE
1 Check solenoid valve SL operation.
PREPARATION:
(a) Remove the oil pan.
(b) Remove the shift solenoid valve SL.
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.
OK:
(a) Solenoid valve does not leak air.
(b) Solenoid valve opens.
NG Replace the solenoid valve SL.

(3) Pull out the dipstick and wipe it clean.
(4) Push it back fully into the pipe.
(5) Pull it out and check that the fluid level is in the HOT
range.
If the level is not within the range, add new fluid.
Fluid type: ATF D-II or DEXRON®III (DEXRON®II)
NOTICE:

Do not overfill.

After filling ATF, check the oil level securely then
drive a vehicle.
(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 D-II or DEXRON®III (DEXRON®II)
Capacity: 4.75 liters (5.0 US qts, 4.2 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
necessary.
NOTICE:
Do not overfill.

(d) Check the fluid leaks.
Check for leaks in the transaxle.
If there are leaks, it is necessary to repair or replace O-rings,
gasket, oil seals, plugs or other parts.
(e) Inspect and adjust the 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 the standard, adjust the cable by 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 aligned with the correct position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures.
(1) Loosen the nut on the shift lever.
(2) Push the control shaft fully downward.
(3) Return the control shaft lever 2 notches to N posi-
tion.
(4) Set the shift lever to N position.
(5) While holding the shift lever lightly toward the R
position side, tighten the shift lever nut.
Torque: 13 N´m (130 kgf´cm, 9 ft´lbf)
(6) Start the engine and make sure that the vehicle
moves forward when shifting the lever from the N to
D position and reverses when shifting it to the R
position.
