This guide requires the following supplies:
Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes.
Secure the vehicle on a level surface, making sure the vehicle will not roll or lean too much when jacked up.
Using a floor jack, raise the front of the vehicle.
Secure the vehicle with jack stands on both sides for safety before starting any work. Do not rely on the jack to hold the vehicle up while working.
Locate the transmission cooler hard lines that run into the radiator and inspect them for leaks.
Disconnect the transmission cooler lines at the radiator and drain the fluid into a drain pan.
Disconnect the transmission cooler lines at the transmission and again drain the fluid into a drain pan.
Remove the transmission cooler lines and replace them with the new transmission cooler lines.
Attach the new cooler lines to the radiator and the transmission as well as any hangers that they may have been suspended from.
Fill the transmission with the manufacturer's recommended fluid to the proper level indicated in Owner's Manual.
Start the vehicle and check the transmission dipstick to make sure the fluid is at the proper level. Top off if needed then road test the vehicle to make sure there are no leaks around the transmission cooler lines.
