AXODE AXOD AX4S AX4N 4F50N Transmission Boost Valve Sonnax 96201-01K

Vehicles with an AXOD, AXODE, 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 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.
