2. Determine whether the transmission oil cooler is
steel or aluminum by using a magnet (1) at the
cooler flange (2) at the radiator.
3. Refer to the table below. Using the temperature from
step 1, locate on either the Steel MINIMUM Flow
Rate table or the Aluminum MINIMUM Flow Rate
table the minimum flow rate in gallons per minutes
(GPM). Record the minimum flow rate in GPMs and
the supply fluid temperature for further reference.
Example:
• Fluid temperature: 75°F
• Cooler type: Steel
The MINIMUM flow rate for this example would
be 0.8 GPM.
4. Inspect transmission oil cooler lines for damage or
kinks that could cause restricted oil flow. Repair as
needed and refer to the appropriate service manual
procedures.

Back Flush Procedure
1. Install both of the J 45096-30 onto the oil cooler
lines.
2. Connect the black supply hose (1) to the adapter
connected to the return line, bottom hose of the
transmission oil cooler.
3. Connect the clear waste hose (2) to the adapter
connected to the supply line, top hose from the
transmission oil cooler.
The above connections are the reverse flow or back-
flush direction.
