Vehicles with an AXOD, AXOD-E, AX4S or AX4N transmission frequently have flare 1-2 & 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 now 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. Valves are hard-anodized for longer life. 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".
