Preparation
J 35944-A Transmission
Oil Coller and Line Flusher
- After the repaired or replacement transmission is installed in
the vehicles, do not reconnect the oil cooler lines.
- Remove the fill cap on the J 35944-A and fill the
can with 0.6 L (20-21 oz.) of flushing solution. Do not
overfill.
- Install the fill cap on the J 35944-A and pressurize
the flusher can, using a shop air supply regulated at 550-700 kPa
(80-100 psi).
- Connect the J 35944-A discharge hose to the oil cooler
return line.
- Clip the discharge hose onto the oil drain container.
- Attach the J 35944-A to the undercarriage of the
vehicle with the hook provided and connect the hose from the J 35944-A
to the other (feed) oil cooler line.
- With the water valve on the J 35944-A in the OFF
position, connect the water hose from the water supply to the J 35944-A.
- Turn ON the water supply at the faucet.
Initial Flush
- Turn the water valve on the J 35944-A to the ON position
and allow the water to flow through the oil cooler lines for 10 seconds to
remove any remaining transmission fluid. If the water does not flow through
the cooler and lines, 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 supply on the J 35944-A to the OFF
position and clip the discharge hose onto the five gallon pail with a lid.
- Turn the water valve on the J 35944-A to the ON position
and depress the trigger to mix 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 lines with water and solution for two
minutes. During this flush, attach the air supply to the air valve located
on the J 35944-A for 3 to 5 seconds at the end of even 15 to
20 second interval to create a surge action.
- Release the trigger and turn the water valve on the J 35944-A
to the off position.
Back Flush
- Disconnect both hoses from the oil cooler lines and then connect
them to the opposite oil cooler line. This will allow the oil cooler and lines
to be back flushed.
- Repeat steps 3 and 4 on the Initial Flush Procedure.
- Release the trigger on the J 35944-A and allow water
only to rinse the oil cooler and lines for one minute.
- Turn OFF the water supply at the faucet.
- Attach the air supply to the valve on the J 35944-A
and blow out the water from the oil cooler and lines. Continue until no water
comes out of the discharge hose.
Flow Check
- Disconnect both hoses from the oil cooler lines. Connect the oil
cooler feed line to the transmission and the return line to the discharge
hose. Refer to Transmission Specifications. Clip the discharge hose onto the
empty oil drain container.
- Confirm the transmission is filled with automatic transmission
fluid. Refer to Specifications for the correct automatic transmission fluid
capacity.
- Start the engine with the transmission in PARK range and run for
30 seconds. A minimum of 1.9 L (2 quarts) must be discharged during
this 30 second fun time.
• | If fluid flow is greater than 1.9 L (2 quarts) in 30 seconds,
go to step 7. |
• | If fluid flow is less than 1.9 L (2 quarts) in 30 seconds,
perform the following diagnosis: |
- Disconnect the oil cooler feed line at the radiator.
- Connect the discharge hose to the cooler feed line. Clip the discharge
hose onto the empty oil drain container.
- Start the engine with the transmission in PARK and run for 30
seconds. A minimum of 1.9 L (2 quarts) must discharge during the 30
second run time. Do the following according to flow rate:
• | Insufficient feed flow: Inspect the transmission. |
• | Sufficient feed flow: Inspect the cooler return line and the cooler. |
- Remove the discharge hose, reconnect the cooler feed and return
lines to the transmission and refill the unit to the proper fluid level Refer
to specifications for the correct automatic transmission capacity.
