Yes you can. These are steel lines that connect one end at the radiator and one end at the transmission and serve to cool the transmission fluid at the radiator. This is a pain in the rear, but it can be done at home with a 5/8" wrench and a screwdriver. The tubing is available at and autoparts store at a reasonable price. The hardest part is removing and replacing the tube at the transmission, but once you figure out how to get to it, you are all set. Good luck.
