Stall Speed
CAUTION:
a To plevent transmission damage, do not test stall speed fot mote than 1O seconds at a time.a Do not shift the level while raising th€ engine speed.a Be sure to remove the pressure gauge belot€ testing stall speed.
1. Engage the parking brake and block all four wheels.
2. Connect the tachometer, and start the engine.
3. Make sure the A/C switch is OFF.
4. After the engine has warmed up to normal operating temperature (the cooling lan comes on), shift into ft position.
5. Fully depress the brake pedal and accelerator for 6 to 8 seconds. and note engine speed.6. Allow 2 minutes for cooling, then repeat the test in [, fDil and @ positions.
NOTE:
a Stall speed tests should be used lor diagnostic purposes only.. Stall speed should be the same in E, tr. tr and @ positions.

Valve Body
Repair
NOTE: This repair is only necessary il one or more of
the valves in a valve body do not slide smoothly in their
bores. You may use this procedure to lree the valves in
the valve bodies.
1. Soak a sheet of #600 abrasive paper in ATF for
about 30 minutes.
2. Carefully tap the valve body so the sticking valve
drops out of its bore.
CAUTION: lt may be necessary to use a small
screwdiiver to pry the the valve lree. Be carelul not
to sclatch the bore with ihe sc.ewdliver.
3. Inspect the valve tor any scuff marks. Use the ATF-
soaked # 600 pagper to polish off any burrs that are
on the valve, than wash the valve in solvent and dry
it with compressed air.
4. Roll up halt a sheet oI ATF-soaked paper and insert
it in the valve bore of the sticking valve.
Twist the paper slightly, so that it unrolls and fits
the bore tightly, then polish the bore by twisting the
paper as you push it in and out.
CAUTION: The valve body is aluminum and doesn't
require much polishing to remove any burs.

7.
Remove the #600 paper and thoroughly wash the
entire valve body in solvent, then dry with com-
perssed air.
Coat the valve with ATF then drop it into its bore.
It should drop to the bottom o{ the bore under its
own weight. lf not. repeat step 4 then retest.
VALVE BODY
Remove the valve and thoroughly clean it and the
valve body with solvent. Dry all parts with com
pressed air, then reassemble using ATF as a
lubricant.

Transmission
Cooler Flushing
S!@ ro prevent iniury to tace and eyes, always
wear safety glas$es or a tace shield when using the trans-
mission flusher.
NOTE: This procedure should be performed before rein-
stalling the transmission.
1. Check tool and hoses for wear or cracks before
using.
lf wear or cracks are found, replace the hoses be-
fore using.
2. Using the measuring cup, tillthe tank with 21 ounces
{approximately 213 lulll of biodegradable tlushing
fluid (J35944-20). Do not substitute with any other
fluid.
Follow rhe handling procedure on the fluid container.
Secure the tlusher filler cap and pressurize the tank
with compressed air to between 550-829 kPa(5.6-8.45 kgt/cm,, 80- 120 psi),
NOTE: The air line should be equipped with a water
trap to ensure a dry air system.
Hang the tool under the vehicle.
Attach the discharge hose of the tank to the return
line of the transmission cooler using a clamp.
Connect the drain hose to the inlet line of the trans-
mission cooler using a clamp. Securely clamp the op-posite end of the drain hose to a bucket or floor drain.

7. With the water and air valves off. attach the water
and air supplies to the flusher. (Hot water it
available.)

8. Turn on the flusher water valve so water will tlow
through the oil cooler for 1O seconds. lf water does
not flow through the oil cooler it is completely
plugged, cannot be flushed, and must be replaced.
9. Depress the trigger to mix the tlushing lluid into the
water tlow. Use the wire clip to hold the trigger
oown.
10. While flushing with the water and flushing fluid for
2 minutes. turn the air valve on for 5 seconds every
15-20 seconds to create a surging action.
AIR PRESSURE:
MAX 829 kPa (8.45 kgt/cm,, 12O psi)
1 1. Turn the water valve off. Release the trigger, then
reverse the hoses to the cooler so you can flush in
the opposite direction. Repeat steps 8 through 1O.
12. Release the trigger and allow water only to rinse the
cooler with water for one minute.
13. Turn the water valve off and turn off the water
supply.
14. Turn the air valve on to dry the system out with air
for two full minutes or until no moisture is visible
leaving the drain hose.
CAUTION: Residual moisture in the oil cooler 01
pipes can damage the transmission.
15. Remove the flusher trom the cooler line. Attach the
drain hose 10 a oil container.
16. lnstallthe transmission and leave the drain hose at-
tached to the cooler line.

Troubleshooting
Noise and Vibration
NOTE: Pump noise in first 2 - 3 minutes after starting in cold weather (-20.C, -4"F or colder) is normal.
Humming
Rattle or chattering
Right cylinder end soal squeak
Pump noise. though not loud,lrom the vslvo bodv unit can be heard when turn-ing the steering wheel right or left. This is normsl.
Humming due to pulsation ol fluid is no.mal, paniculady when wheel is turnedwith ca. stopped.
lf equipped with automatic trans-mission, the hum could b€ tor-que convener or pump notse.
Confirm by temporarily removingpump b€lt.

Column shaft wobbling.Replace column assembly.
Check the rack guide for properadjustment (16o page 17-21).Adjust, if n€ca€ssry.
Rattling sound and feeling when turning the steoring wheel right and lett with thoengine OFF is a sound when th6 valve unit contacts tho stopper. This is normal.
Striking sound wh6n turning the ste€ring whoglfully right o. left is a sound whenthe r6ck end contacts th6 stopper. This is normal.

Windshield
Installation (cont'd)
With a sponge. apply a light coal oJ glass primer
around the edge ot the windshield as shown, then
lightly wipe it olt with gauze or cheesecloth.
NOTE:
a Do not apply body primer to the windshield, and
do not get body and glass primer sponges mlxed
up.
a Never touch the primed surfaces with your hands.
ll you do, the adhesive may not bond to the wind-
shield properly, causing a leak afterthe windshield
