Bypass tube eliminator kit for Ford 4R100 transmissions (1999–2003). The kit removes the OEM cooler bypass tube assembly—which can fail and bypass the cooler—and replaces it with two aluminum shunts and sealing washers to prevent unwanted bypassing. It’s a recommended preventative maintenance item when installing transmissions, coolers or filter kits and simplifies service work during rebuilds or cooler upgrades.
