Installation

This hose is a direct OEM replacement and is designed to bolt on or connect in the same routing as the factory original with no cutting, splicing, or modification required. Basic mechanical experience and standard hand tools are sufficient for most installations; however, we recommend having the vehicle inspected and the hose replaced by a qualified Subaru technician to ensure proper torque specifications and system integrity. Always drain residual ATF before removal and top off transmission fluid after installation.
