How to Change the Transmission Oil Cooler Hose on GMC Sierra 1500?

The first step to replace the transmission fluid cooler hose/pipe begins with removing the front grill assembly. The transmission fluid cooler hose needs to be removed from both the auxiliary Oil Cooler and the Radiator during the first step. The first step requires vehicle elevation and subsequent removal of the transmission cooling line bracket retaining bolt followed by draining all transmission and oil cooling lines from the vehicle. During installation you should connect the transmission Oil Cooler lines first to the vehicle before connecting them to the transmission while also fastening and tightening the transmission cooler line bracket bolt to 22 nm (16 lb ft). The installation requires you to lower the vehicle while attaching both the transmission fluid cooler hose to the Radiator and auxiliary Oil Cooler. The last installation step involves solving the front grill assembly.

How to replace the Transmission Oil Cooler Hose on GMC Yukon?

The first step for replacing the transmission fluid cooler hose/pipe requires front bumper fascia removal. Take out the fasteners from the front upper fascia support bracket to enable its backward tipping motion. Removal of the transmission fluid cooler hose must occur first from connecting to both the auxiliary Oil Cooler and Radiator. The first step includes raising the vehicle then removing the engine protection shield from its position. After disconnecting transmission cooling lines workers should remove right differential carrier mounting nuts together with washers by hand due to necessary proper bolt torques for accurate diagnosis. The right front shock rear mounting bolt at the lower Control Arm must be removed first before moving the oil-cooling lines toward the rear of the vehicle. The first step for installation requires fitting the transmission Oil Cooler lines to the vehicle without using air-powered tools.
