Repair and Replacement Guidelines
- Safety: Work on a cooled vehicle on stable lifts/stands; avoid hot fluid burns.
- Small rubber hose leak: Replace with OEM-spec reinforced hose and new clamps; use correct ATF-rated hose.
- Hard line leak (corroded/cracked): Replace the damaged section or full line; copper-nickel is easier to flare and repair than steel.
- Fittings: Replace damaged quick-disconnects, O-rings, or crush washers; use correct torque on threaded fittings.
- Flare fittings: Use proper flaring tools and replace any line with damaged flares.
- After replacement: Refill ATF to specified level, bleed air if required (some transmissions need specific procedures), and run through gears to circulate fluid; recheck for leaks.
- Professional repair recommended if lines run through frame rails, are brazed, or if transmission internal work is needed.
