Function: Hydraulically actuates clutch packs (3-5/R or 4-5-6 clutches) in Nissan/Infiniti FWD applications.

Kit Components:

• Bonded Pistons: Aluminum with updated Viton seals (OEM 31705-3X20B) for high-temp stability.

• Return Springs: Upgraded fatigue-resistant design (prevents slow release).

• Seals: Pre-lubricated for immediate pressure retention.

Failure Modes:

• Seal Roll-Over: Improper installation causes leaks (delayed engagement).

• Spring Collapse: Leads to clutch drag (burnt plates, P0776 codes).

• Piston Cracking: Fatigue near apply lugs (causes pressure loss in 5th gear).

Critical Specs:

• Apply pressure: 45-65 psi (test with air pressure tool).

• Seal groove clearance: <0.15mm.

Pro Tip: Soak seals in ATF for 1 hour pre-install – dry seals tear during initial actuation
