Transmission Fluid Cooler - Backflushing and Cleaning
NOTE: Transmission fluid cooler backflushing and cleaning will be performed using the Transmission Heated Cooler Line Flusher or equivalent.
Follow the manufacturer's instructions included with the machine. Test the equipment to make sure that a vigorous fluid flow is present before
proceeding.
NOTE: If the vehicle is equipped with an in-line transmission fluid thermal by-pass valve, the in-line transmission fluid thermal by-pass valve must be
removed prior to flushing out the transmission fluid cooler and transmission fluid cooler lines.
1. Check and top off fluid level of the cooler line flusher tank with transmission fluid.
2. Allow the fluid in the cooler line flusher 15-30 minutes to heat up to 60°C (140°F) before using.
3. Install the line adapters into the transmission cooler lines.
4. Attach the cooler line flusher red line to the transmission fluid cooler pressure line quick disconnect fitting.
5. Attach the cooler line flusher blue line to the transmission fluid cooler return line quick disconnect fitting.
6. Follow the equipment instructions to purge the cooler lines and cooler prior to starting the flushing procedure.
7. Allow the cooling system to backflush for 10-15 minutes, then flush the cooler in a normal flow direction for an additional 10-15 minutes.
8. If equipped, clean the in-line transmission fluid thermal by-pass valve by hand.

Check Transmission Fluid Level and Condition
NOTICE: The vehicle should not be driven if the transmission fluid level indicator shows the transmission fluid below the minimum fluid level
mark or internal failure may result.
If the vehicle has been operated for an extended period of time at highway speeds, in city traffic, in hot weather or while pulling a trailer, the
transmission fluid may need to cool down to obtain an accurate reading.
The transmission fluid level reading on the transmission fluid level indicator will differ depending on operating and ambient temperatures. The correct
