  Q: How to replace the Transmission Oil Cooler Hose on GMC Sierra 1500 Classic?

  A: The replacement process for transmission fluid cooler hose/pipe begins by taking the grille assembly off. The transmission fluid cooler hose requires disconnecting both from the auxiliary Oil Cooler and Radiator through quick-connect fitting procedures. To start the replacement raise the vehicle until it reaches proper height then remove the engine protection shield. Begin by disconnecting first the transmission fluid cooler hoses both from the transmission and from the retainer on the engine before removing them from the vehicle. The first installation step involves connecting the transmission fluid cooler hoses to the vehicle then to the transmission while affixing them to the engine retainer. Put back the engine protection shield then drop the vehicle and join the transmission fluid cooler hose to the Radiator and the auxiliary Oil Cooler. Finally, reinstall the grille assembly.
