I plan to replace the long transmission oil cooler line as the original is finally starting to leak at the rubber hose to aluminum connection and the leaking oil sender - will first degrease under the engine with carb cleaner spray and clean the engine bay with foaming degreaser

 

If you are replacing the line that connects to the top of the transmission, you will probably need to drop the Y-pipe. Be ready to deal with the studs from the exhaust manifold which often are troublesome.

 

It is a hard access, but you don't need to do that
