The transmission-cooler hose is normally 3/8-inch inside diameter. Before buying it, measure the metal cooler-line nipple where the hose attaches; it should be approximately 3/8 inch. The SAE J1019 high-temperature oil hose can also be used for automatic transmission fluid, but SAE J1532 is the more directly applicable specification. Let me know if you need anything else.
