Pressure Testing
a While testing, be caretul of the rotating flont wheels.a Make aura litts, jacks, and sat€ty stands alo placedplop6rly {see section 1}.
CAUTION: Betore t€sting, be sure the transmission fluidis tilled to rh6 ploper l€vet.
1. Raise the car (see section i),
2. Warm up the engine {the cooling fan comes onl, thenstop the engine and connect a tachometer.
3. Connect the oil pressure gauge to each inspectionholels).
TOROUE: 18 N.m (1.8 kgf.m, 13 tbf.fr)
CAUTION: Connect ths oil prsssure gauge s€cur€_ly; be sule not to allow dust and other foleign pani_cl6s to 6nt€1 th€ inspection holo.

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.)
OFF
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.
