Part Summary
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. This boost valve kit for both 3.0 and 3.8 liter applications and sleeve with o-rings will eliminate the above problems when installed properly.
Features & Benefits
• Sleeve is made from high-quality aluminum to prevent wear.
• Valve is hard-anodized for longer life.
• O-ring sleeve prevent leakage between the sleeve and valve body bore.
THIS IS A MUST FOR ANY UNIT. THE PROBLEM IS THE BOOST VALVE WEARS THE INSIDE DIAMETER OF THE BOOST SLEEVE AND CAUSES OIL TO LEAK & EXHAUST THROUGH THE REVERSE ORIFICE, RESULTING IN POOR LINE RISE. THIS PART IS WORTH THE MONEY.
PLEASE NOTE:
THIS KIT MUST BE INSTALLED IN THE VALVE BODY WHICH IS INSIDE THE SIDE COVER PAN. SOMETIMES YOU MUST LOWER OR REMOVE THE TRANSMISSION TO REMOVE THE SIDE PAN AND VALVE BODY.
THIS ITEM MAY NOT COME IN RETAIL PACKAGING.
