CAUTION: Test the torque converter/fluid cooler cleaner to make sure that a vigorous fluid flow is present before proceeding. Install a new system filter if flow is weak or contaminated.
CAUTION: Prior to backflushing and cleaning the transmission fluid cooler tubes check for the components listed. If installed or equipped, they must be removed from the cooler tubes and discarded. Any components removed must be installed new.
CAUTION: Contamination can become trapped in the coolers. Clean fluid flow after flushing does not always indicate all contamination has been removed.
  1. Using a suitable torque converter/fluid cooler cleaner, flush the fluid cooler and lines.
  2. If equipped, remove and discard the transmission fluid in-line filter.
