Boost Valve Kit Sonnax (Except 3.0) 4F50N AX4N AX4S AXOD AXODE

Boost Valve Kit Sonnax (Except 3.0) 4F50N AX4N AX4S AXOD AXODE Vehicles with Ford AXOD, AXODE, AX4S or AX4N transmissions frequently have flare 1-2 and 2-3 upshifts, high pressure, harsh Reverse (300 psi), 2-1 downshift clunk, non-adjustable throttle pressure and clutch or band failure from poor line rise. This is caused by wear on the inside bore of the boost sleeve allowing TV/EPC and/or Reverse oil to either leak to exhaust or cross-leak. Sonnax offers boost valve kits for both 3.0 and 3.8 liter applications and sleeves with or without O-rings (factory style) to eliminate the above problems. Sleeves are made from high-quality aluminum to prevent wear Hardcoat anodized aluminum valve combats premature wear O-ring sleeves prevent leakage between the sleeve and valve body bore Available in two sizes: 96201-12K (O-ring style) and 96201-13K (factory style) with a small diameter boost valve of .475"; 96201-01K (O-ring style) and 96201-08K (factory style) with a small diameter boost valve
