Transmission
Gooler Flushing
@ To prevent iniury to face and eyes, alwayswear safety glasses or a tace shield when using thetransmission flusher.
NOTE: This procedure should be performed before rein-stalling the transmission.
'1. Check the tools and hoses for wear and cracks before
using. lf wear or cracks are found, reDlace the hoses
before using.
4.
Using the measuring cup. fill the tank with 2,1 ounces(approximately 2/3 full) of biodegradable flushingfluid (J35944 - 20). Do not substitute with any otherfluid. Follow the handling procedure on the fluidcontatner.
Secure the flusher filler cap, and pressurize the tankwith compressed air to between 5S0 - 829 kpa (5.6 -
8.45 kgf/cm', 80 - 120 psi).
NOTE: The air line should be equipped with a watertrap to ensure a dry air system,
Hang the tool under the vehicle.
Attach the tank's discharge hose to the return lineoi the transmission cooler using a clamp.
Connect the drain hose to the inlet line on the trans-mission cooler using a clamp.
IMPORTANT:
Securely clamp the opposite end ofthe drain hose to abucket or floor drain,

7. With the water and air valves off, attach the water andair supplies to the flusher. (Hot water if available.)
8. Turn on the flusher water valve so water will flowthrough the cooler for 10 seconds.
NOTE: lf water does not flow through the cooler, itis completely plugged, cannot be flushed, and mustbe replsced.
9. Depress the trigger to mix the flushing fluid into thewater flow. Use the wire clip to hold the trigger down.
'10. While flushing with the water and flushing fluid fortwo minutes. turn the air valve on for five secondsevery 15 - 20 seconds to create a surging action.AIR PRESSURE: MAX 845 kpa (8.45 kgflcmr, 120 psi)
11. Turn the water valve off. Release the trigger, thenreverse the hoses to the cooler so you can flush inthe opposite direction. Repeat steps 8 through 10.
12. Release the trigger. and rinse the cooler with wateronly 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 airfor two full minutes or until no moisture is visibleleaving the drain hose.
CAUTION: Rosidual mobturo in the qooler or linescln damage the transmission,
15. Remove the flusher from the cooler line. Attach thedrain hose to a container.
16. Install the transmission. and leave the drain hoseattached to the cooler line.

17.Make sure the transmission is in the E] position.
Fill the transmission with cvT Fluid, and run the
engine for 30 seconds or until approximately 0 95 {
(1.0 US qt.,0.8 lmp qt.) is discharged.
Remove the drain hose, and reconnect the cooler
return hose to the transmission (see page 14-355)
Refill the transmission with CVT Fluid to the proper
level (see page 14-299).

TOOL MAINTENANCE
1. Empty and rinse after each use. Fill the can with water
and pressurize the can. Flush the discharge line to
ensure that the unit is clean.
2, lf discharge liquid does not foam, the orifice may be
blocked.
3. To clean, disconnect the plumbing from the tank at
the large couPling nut.

3. Check that the hole in the adiuster is perfectly aligned
with the hole in the shift cable. There are two holes in
the adjuster. They are positioned 90" apart to allow
cable adjustment in 1/4 turn increments.
lf the hole is not perfectly aligned, loosen the lock-
nut on the adjuster and adjust as required.
Tighten rhe locknut to 7 N.m (0.7 kgim,5 lbf'ft).
Install the lock pin on the adjuster' lf you feel the
lock pin binding as you reinstall it. the cable is still
out of adjustment and must be readjusted
Make sure the lock pin is seated in the adiuster
securery.
lMove the shift lever to each position, and verify that
the shift position indicator follows the automatlc
transaxle gear position switch.
Start the engine, and check the shift lever in all
positions. lf any gear does not work properly, refer
to troubleshooting (see page 14-294 and 14-295).
Insert the ignition key into the key cylinder on the
Aff gear position indicator panel, and verify that the
shift lock lever is released.
