(3) With the engine OFF, add new fluid through the oil
filler pipe.
Fluid type: ATF DEXRON ®II
Capacity:
Dry fill: 11.0 liters (11.6 US qts, 9.7 Imp. qts)
Drain and refill: 1.9 liters (2.0 US qts, 1.7 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,
Seal packings, oil seals, plugs or other parts.
(e) Inspect and adjust the throttle cable. (1) Check that the throttle valve is fully closed.
(2) Check that the inner cable is not slack.
(3) Measure the distance between the outer cable endand 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 correctly indicates the position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures. (1) Loosen the nut on the control rod.
(2) Push the control rod fully rearward.

8. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation ATF temperature 50 − 80°C (122 − 176° F).
The line pressure test should always be carried out in pairs. One techni\
cian should observe
the conditions of wheels or wheel stoppers outside the vehicle while the ot\
her is doing the test.
Be careful to prevent SST’s hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the transmission case right side and connect SST\
(See page AT−18
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 p\
osition.
(6) Measure the line pressure when the engine is idling.
(7) Press the accelerator pedal all the way down. Quickly read the highest line pr\
essure 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 the specified stall speed.
(8) In the same manner, do the test in R position.
Specified line pressure:
Condition D position kPa (kgf/cm2, psi) R position kPa (kgf/cm2, psi)

ttle cable adjustment and retest.

Author: Date:
1996 LAND CRUISER (RM451U)
COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. DISCONNECT DISTRIBUTOR CONNECTOR
3. REMOVE SPARK PLUGS (See page IG−1 )
4. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible. Compression pressure:
1,176 kPa (12.0 kgf/cm
2, 171 psi) or more
Minimum pressure: 883 kPa (9.0 kgf/cm
2, 128 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
If the cylinder compression in one or more cylinders is low, pour
a small amount of engine oil into the cylinder through the spark
plug hole and repeat steps (a) through (c) for cylinders with low
compression.
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.
If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS (See page IG−1 )
6. RECONNECT DISTRIBUTOR CONNECTOR

SHAFT GEAR
Using a dial indicator with lever type attachment, measure the
thrust clearance.
Standard thrust clearance:
0.040 − 0.160 mm (0.0016 − 0.0063 in.)
Maximum thrust clearance: 0.30 mm (0.0118 in.)
If the thrust clearance is greater than maximum, replace the oil
pump drive shaft gear and/or timing chain cover.
16. REMOVE DRIVE BELT IDLER PULLEY
Remove the bolt and idler pulley.
17. REMOVE TIMING CHAIN COVER
(a) Remove the 9 mounting bolts, 2 mounting nuts and drive belt adjusting bar.
(b) Remove the oil pump by prying the portions between the cylinder block and oil pump with a screwdriver.
