How to replace the Transmission Oil Cooler Hose on Buick LeSabre?

Starting the transmission fluid cooler hose/pipe replacement procedure requires pulling the plastic cap from the quick connect fitting and lowering it down the cooler line by 5 cm (2 inches). You should use a bent-tip screwdriver to grab one open end of the retaining ring at the quick connect fitting so you can rotate it until removal. Pull the cooler line out directly from the quick connect fitting after discarding the retaining ring. The installation of new retaining rings necessitates completely fresh replacement of all oil lines together with both their fittings and rings. Position one open end of the new retaining ring through the slot of the quick connect fitting then rotate it counterclockwise until all three slots accept its ear parts. The retaining ring should easily fit into the slots without resistance and show itself inside the fitting. Fitting the cooler line into the quick connect will complete when a distinct click sound occurs without resorting to the plastic cap for this purpose. You need to pull on the cooler line with force to confirm proper attachment in the fitting. When fitting the plastic cap to the fitting avoid touching the retaining ring manually while making sure the fitting has a complete seating with zero gaps present along with the yellow tube identification band totally hidden to confirm proper joint seating. The transmission needs to be filled up to proper levels using DEXRON(R)iii transmission fluid.
