How Can the Transmission Cooling Lines Be Removed?

There are two transmission cooling lines located on the sides of the transmission that can be removed using a flare nut wrench to loosen the nut that holds the lines in place. To locate the transmission cooling lines, open the hood of the vehicle and trace the two lines from underneath the vehicle all the way to the transmission. The transmission cooling lines should be removed from the connecting point underneath the radiator.

To access the bottom side of the radiator and reach the transmission cooling lines, lift the front of the vehicle with floor jacks positioned on both sides of the frame. The floor jacks are responsible for supporting the weight of the vehicle.

The transmission cooling lines are responsible for routing the transmission fluid from the radiator to the front of the vehicle. The transmission fluid acts as a lubricant to prevent the transmission, which is responsible for changing the gears of the vehicle, from overheating and for extending the lifespan of all of the internal parts. Remember to drain all of the transmission fluid from the transmission before removing the transmission cooling lines. To remove the transmission fluid, unscrew the drain plug with a wrench. Next, use the blade of a flathead screwdriver to remove the pan.
