CAUTION: Make sure the cooler bypass valve (CBV) is correctly backflushed. Use dry compressed air to remove solvent.

CAUTION: If the cooler line case fitting is overtightened, the rubber-coated sealing washers and/or cooler line case fittings can be damaged, causing a transmission fluid leak.

NOTE: The CBV has a check ball in the rear fitting and will only allow flow in one direction. Make sure check ball moves freely.

NOTE: Align the two rubber-coated sealing washers while assembling the rear cooler line case fitting.
