Preparation
Tools Required
Notice: Whenever you remove the transmission for service, you must perform the
automatic transmission oil cooler flushing procedure in order to remove the
existing fluid which may be contaminated. This will prevent contamination
of the new fluid. You must perform the flushing procedure after the installation
of the overhauled or replacement transmission.
Notice: Only use J 35944-20 Cooler Flushing Fluid with the J 35944-A
Oil Cooler and Line Flusher. Use of any other fluid can result in damage to
the tool, damage to the automatic transmission oil cooler components, or improper
flushing of the cooler. Do not reconnect the oil cooler pipes after you reinstall
the overhauled or service replacement transmission in the vehicle.
- Remove the fill cap onJ 35944-A
and fill the can with 0.6 liter (20 -21ounces) J 35944-22
. Do not over fill.
Notice: Shop air supply must be equipped with a water/oil filter and not exceed
825 kPa (120 psi), or personal injury may result.
- Install the fill cap onJ 35944-A
and pressurize the flusher can using the shop air supply to
550-700 kPa (80-100 psi).
- Connect the J 35944-A
discharge hose to the oil cooler return (top fitting). Use J 35944-200
if required.
- Clip the discharge hose onto the oil drain container.
- AttachJ 35944-A
to the undercarriage of the vehicle with the hook provided and connect the
hose from J 35944-A
to
the feed (bottom fitting) oil cooler pipe. Use J 35944-200
if required.
- Turn ON the water supply at the faucet.
Initial Flushing
Notice: If water does not flow through the oil cooler (system is completely
plugged), do not continue the flushing procedure, or damage to the tool or
components could result. Turn the water OFF immediately. Inspect the pipes
and the cooler for restrictions. Replace the oil pipe(s) and/or the oil cooler.
- Turn the water valve on J 35944-A
to the ON position and allow the water to flow through the
oil cooler and pipes for 10 seconds to remove any remaining transmission fluid.
If water does not flow through the oil cooler and pipes, the cause of
the blockage must be diagnosed and the plugged component must be repaired
or replaced. Continue with the cooler flushing and flow check procedure
once the blockage is corrected.
- Turn the water valve on J 35944-A
to the OFF position and clip the discharge hose onto a five
gallon pail with a lid. If there is no lid, place a shop towel over the end
of the hose in order to prevent splash.
- Turn the water valve on the J 35944-A
to the ON position and depress the trigger to mix the cooler
flushing solution into the water flow. Use the clip provided on the handle
to hold the trigger down. The discharge will foam vigorously when the
solution is introduced into the water stream.
- Flush the oil cooler and pipes with water and solution for two
minutes. During this flush, attach the air supply to the air valve located
on J 35944-A
for 3 to
5 seconds at the end of every 15-20 second interval to create a
surging action.
- Release the trigger and turn the water valve on J 35944-A
to the OFF position.
Backflush
| • | Disconnect both hoses from the oil cooler pipes and then connect
them to the opposite oil cooler pipe. This will allow the oil cooler and pipes
to be back flushed. |
| • | Repeat step 3 and 4 of the INITIAL FLUSH procedure. |
| • | Release the trigger of J 35944-A
and allow water only to rinse the oil cooler and pipes for
one minute. |
| • | Turn the water valve on J 35944-A
to the OFF position and turn OFF the water supply at the faucet. |
| • | Attach the air supply to the air valve on J 35944-A
and blow out the water from the oil
cooler and pipes. Continue until no water comes out of the discharge hose. |
Flow Check
- Disconnect both hoses from the oil cooler pipes. Connect the oil
cooler feed pipe to the transmission and the return pipe to the discharge
hose (bottom fitting). Clip the discharge hose onto the empty oil drain
container.
- Confirm the transmission is filled with automatic transmission
fluid. Refer to
Fluid Capacity
for the correct automatic transmission fluid capacity.
- Start the engine with the transmission in PARK and run the engine
for thirty seconds. A minimum of 2 quarts (1.9 L) must be discharged
during this thirty second run time. If fluid flow is greater than two quarts
in thirty seconds, perform the following diagnosis:
| 3.1. | Disconnect the oil cooler feed line at the radiator. |
| 3.2. | Connect the discharge hose to the cooler feed line. |
| 3.3. | Clip the discharge hose onto the empty oil drain container. |
| 3.4. | Start the engine with the transmission in PARK and run the engine
for thirty seconds. A minimum of two quarts (1.9 L) must be discharged
during this thirty second run time. Do the following according to the flow
rate: |
| • | Insufficient feed flow: Inspect the transmission |
| • | Sufficient feed flow: Inspect the oil cooler return pipe and the
oil cooler. |
- Remove the discharge hose, reconnect the cooler feed and return
pipes to the transmission and refill the unit to the proper fluid level. Inspect
the transmission oil cooler pipe connections at the radiator, and transmission
for leaks.
Clean-up
- Disconnect the water supply hose from J 35944-A
and bleed any remaining air pressure from the can.
- Remove the fill cap from J 35944-A
and return any unused flushing solution to its container.
Rinse J 35944-A
with water.
Do not store J 35944-A
with flushing solution in it.
- After every third use, clean J 35944-A
as described in the instructions included with the tool.
- Dispose of any waste water/solution/transmission fluid in accordance
with local regulations.
