Pressure Testing
a While testing, be careJulot the rotating front wheels.
a Make sule litts, iacks, and safety stands are placed
properly (see section 1).
CAUTION: Befoie testing, be sure the transmission fluid
is filled to the proper level.
'1. Raise the vehicle {see section 'll.
2. Warm up the engine (the radiator fan comes on),
then stop the engine and connect a tachometer.
3. Connect the special tool to each inspection hole(s).
TOROUE: 18 N.m l1-8 kgt.m, 13lbf.ftl
CAUTION: Connect the A/T pressure gauge secure-
ly, be sure not to allow dust and olher foreign pani-
cles to enter the inspection hole.

a Clutch Pressure
a Clutch Low/High Pressure
a Throttle B Pressure
5. Install a new sealing washer and the sealing bolt in
the inspection hole and tighten to the specified
torque.
TOROUE:18 N.m (1.8 kgf.m, 13lbf.ft)
NOTE: Do not reuse old sealing washers; alwaysreplace washers.
Line Pressure Measurement
-1. Set the parking brake, and block both rear wheels
securely.
-2. Run the engine at 2,000 rpm
3. Shift to S or @ position.

Cooler Flushing
S@ to pttvont iniury to face and syes' always
w6ar safety glassos or a face 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 and cracks before
using. lf wear or cracks are found, replace the hoses
before using.
2. Using the measuring cup, fill the tank with 21 ounces
(approximately 2/3 full) of biodegradable tlushing
fluid {J35944-20). Do not substitute with any orher
tluid. Follow the handling procedure on the tluid
contalner.
3. Secure the flusher filler cap, and pressurize the tank
with compressed air to between 550-829 kPa
{5.6-8.45 kgf /cm', 80- 120 Psi}.
NOTE: The air line should be equipped with a water
trap to ensure a dry air system.
4. Hang the tool under the vehicle
5. Attach the discharge hose of the tank to the return
line oI the transmission cooler using a clamp
6. Connect the drain hose to the inlet line of the trans-
mission coolel using a clamp. Securely clamp the op-
oosite end of the drain hose to a bucket or tloor drain.

7. With the water and air valves ofl, atach the water
and air supplies to the flusher. (Hot water if
available.)
8. Turn on the flusher water valve so water will flow
through the ATF cooler for 10 seconds. lf water does
not flow through the ATF cooler, it is completely
plugged, cannot be flushed, and must be replaced
9. Depress the trigger to mix the flushing fluid into the
water flow. Use the wire clip to hold the trigger
oown.
1O. While tlushing with the water and llushing f luid for
two minutes. turn the air valve on for five seconds
everv 15-20 seconds to create a surglng actlon.

1 1. Turn the water valve off. Release the trigger. then
reverse the hoses to the cooler so you can flush in
the ooDosite 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 oJf 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 ATF coolei 01
pipos can damage the transmission.
15. Remove the flusher {rom the cooler line. Attach the
drain hose to a fluid contaaner.
16. Installthe transmission and leave the drain hose a1-
tached to the cooler line.

17. Make sure the transmission is in E] position.
Fill the transmission with ATF, and run the engineJor 30 seconds or until approximately one quart isdischarged.
'18. Remove the drain hose, and reconnect the coolerreturn hose to the transmission.
19. Refillthe tiansmission with ATF to the propef level.
FILLER CAP
TOOL MAINTENANCE
1. Empty and rinse after each use. Fill the can withwater and pressurize the can. Flush the dischargeline to ensure that the unit is clean.
2. lf discharge liquid does not foam, the orifice may beblocked.
3, To clean, disconnect the plumbing from the tank atthe large coupling nut,
4. Remove the in-line filter trom the discharge side andclean if necessary.
5. The fluid oritice is located behind the filter.
Clean it with the pick stored in the bottom of the tankhandle or blow it clean with air. Securely reassem-
ble all parts.
