How to replace the Transmission Oil Cooler Hose on GMC Savana 3500?

Question

Accepted Answer

The first task to replace the transmission fluid cooler hose/pipe requires physically elevating the vehicle and using stable safety stands for support. You must disconnect the 2 oil cooler lines which run through the Radiator before handling the outlet pipe from an optional auxiliary transmission oil cooler. Start by detaching transmission oil lines from their position on both the cooler and frame rail where they are held by clips. When working with quick connect fittings on the transmission to extract their retaining ring and cooler line you should carefully pull the plastic cap beyond a two-inch distance from the fitting. Yo u can easily disassemble the retaining ring by rotating it with the help of a bent-tip screwdriver and should dispose of it afterward. Use pliers or fingers to pull out the cooler line directly from its quick connect fitting and unfasten the e-clips retaining rings until you can extract the cooler lines from both the vehicle and drop it to the floor. The installation requires vehicle elevation to put in the new transmission oil cooler line lines while keeping all factory retaining rings out of use. Fit one new e-clip into the quick connect fitting and connect both cooler lines to the Radiator system while you should also install the inlet to the Radiator and outlet to the auxiliary cooler line if needed. Secure both transmission-connected oil cooler lines by checking that the retaining ring correctly slots all of its three ears into the fitting ports. The new retaining ring (E-clip) needs to be placed into the vacant quick connect fittings after checking for free movement of the rings through their slots. The installation requires plastic caps for each end of the cooler line and immediate replacement if any damage exists. To secure the cooler line properly insert it into the quick connect fitting until either a sound or resistance can be felt and then apply strong backward force for confirmation. Ensure proper fitting placement of the plastic cap by avoiding hand pressure on the retaining ring while making sure the fitting rests completely with no space between components and hiding the yellow identification band inside. Check for bends on retaining rings before reinstallation because incorrect positioning of the plastic cap requires removing the retaining ring for proper inspection. You should install the engine or transmission cooler lines to the frame by lowering the vehicle down.
