On certain Ford vehicles, when disconnecting a transmission line for service, the O-ring is usually unable to be reused. Because Ford does not sell the O-rings separately, replacing the entire line or risking a leak are the only options. This pack of eight OE FIX O-rings allows direct replacement of the O-rings in these applications, allowing you to replace just the service item, not the complete assembly. This part is compatible with the following vehicles. Before purchasing, enter your vehicle trim in the garage tool to confirm fitment.
