Sonnax Oversized 4-3 Sequence Valve Kits

Continuous oscillation in relay valve and sequence valve bore causes wear that prevents proper hydraulic control. You can recover hydraulic control and renew 2nd and 4th gear operation by reconditioning the entire bore and installing a Sonnax oversized 4-3 sequence valve kit. These kits address wear on the inboard two spools that is increasingly more common in aging valve bodies. Wearing at these spools can allow valuable 4th servo feed leakage, resulting in no 4th and 2-4 band wear, and can also allow leakage of 2nd clutch oil needed to apply the 2-4 band in 2nd gear, resulting in poor 2nd gear shifts. Leaking at the OE end plug also allows oil loss that can leave 4th gear inoperable. Sonnax oversized 4-3 sequence valve kits feature hardcoat anodized aluminum valves to combat premature wear and O-ringed end plugs to help prevent 4th gear oil loss.
