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 of .491" Drop-in Zip Valve™ parts install quickly and easily
