stall speed range on the tachometer scale.
3) Place the wheel chocks at the front and rear of
all wheels and engage the parking brake.
4) Move the manual linkage to ensure it operates
properly, and shift the select lever to the 2 range.
5) While forcibly depressing the foot brake pedal,
gradually depress the accelerator pedal until the
engine operates at full throttle.
B3M0286B
6) When the engine speed is stabilized, read that
speed quickly and release the accelerator pedal.
7) Shift the select lever to Neutral, and cool down
the engine by idling it for more than one minute.
8) Record the stall speed.
9) If stall speed in 2 range is higher than
specifications, low clutch slipping and 2-4 brakeslipping may occur. To identify it, conduct the same
test as above in D range.
10) Perform the stall tests with the select lever in
the R range.
NOTE:
IDo not continue the stall test for MORE THAN
FIVE SECONDS at a time (from closed throttle,
fully open throttle to stall speed reading). Failure to
follow this instruction causes the engine oil and
ATF to deteriorate and the clutch and brake to be
adversely affected.
Be sure to cool down the engine for at least one
minute after each stall test with the select lever set
in the P or N range and with the idle speed lower
than 1,200 rpm.
IIf the stall speed is higher than the specified
range, attempt to finish the stall test in as short a
time as possible, in order to prevent the automatic
transmission from sustaining damage.Stall speed (at sea level):
2200 cc 2,200 Ð 2,600 rpm

14. Control Valve Body
A: PRECAUTION
The control valve is composed of parts which are
accurately machined to a high degree and should
be handled carefully during disassembly and
assembly. As these parts are similar in shape, they
should be arranged in neat order on a table after
disassembly so that they can be easily installed to
their original positions. Spring loaded parts shouldbe also handled carefully, as springs may jump out
of place when the parts are disassembled or
removed. Extreme care should be taken so as not
to drop valves on the floor. Before assembling, the
parts and valves should be dipped in a container
filled with the ATF. Make sure that the valves are
clean and free from any foreign material before
assembly. Torque specifications should also be
observed.

B: INSPECTION
1) Check seal ring and O-ring oil seal for breaks or
damage.
2) Check other parts for dents or abnormalities.
3) Selection of oil pump rotor assembly
(1) Tip clearance
Install inner rotor and outer rotor to oil pump.
With rotor gears facing each other, measure
crest-to-crest clearance.
Tip clearance:
0.02 Ð 0.15 mm (0.0008 Ð 0.0059 in)
B3M0965A
(2) Side clearance
Set a depth gauge to oil pump housing, then
measure oil pump housing-to-rotor clearances.
Side clearance:
0.02 Ð 0.04 mm (0.0008 Ð 0.0016 in)
