With one end of the retaining clip engaged in the connector fitting slot, use your thumb in order to rotate the retaining clip around the connector fitting, until the retaining clip snaps into place.

Important: A distinct snap should be heard when assembling the cooler line to the quick connect fitting. To ensure the cooler line is fully inserted into the quick connect fitting, give the cooler line a gentle pull.

Do not use the plastic cap in order to install the cooler line into the fitting.
Install the cooler line straight into the quick connect fitting until a click is either heard or felt.
Pull back gently on the cooler line in order to ensure that the cooler line is installed in the quick connect fitting.

Important: Ensure the cooler line being installed has a plastic cap on the end that connects to the quick connect fitting. If no plastic cap exists, or the plastic cap is damaged, obtain a new cap. Install the cap on to the cooler line prior to cooler line installation.

Do not manually depress the retaining clip when installing the plastic cap.
Snap the plastic cap onto the quick connect fitting.
Ensure that the plastic cap is fully seated against the fitting.
Ensure that no gap is present between the cap and the fitting.
Run the engine. Inspect the transmission oil cooling system for leaks.
Inspect the fluid levels. Add fluid if necessary.
