The steel throttle valve plunger continuously reciprocates within the aluminum throttle valve plunger sleeve, wearing the sleeve. This wear allows throttle valve feed oil to leak past the plunger and exhaust, resulting in poor line rise and problematic downshifts. In addition, the OE spring is weak and can result in low line rise, insufficient throttle pressure and, ultimately, 3-4 clutch failure. Sonnax throttle valve plunger valve kit 77966-94MK includes an improved throttle valve spring designed to maintain higher line pressure and improved TV performance.Sleeve is made from high-quality aluminum to prevent wear.Sleeve and plunger have been tightly toleranced to restore hydraulic integrity.ContentsSpringSleevePlungerAPPLICATIONS Buick Roadmaster 1992-1993Cadillac Fleetwood 1990-1992 4SPD RWDChevrolet Astro Van 1987-1992Astro Van 1989-1992 4SPD 4X4Blazer 1987-1993 4SPD 4X4Camaro 1987-1992 4SPD RWDCaprice 1987-1993 4SPD RWDCorvette 1987-1993Suburban 1990-1992 1/2 TON 2WD 4WDTruck 1983-1992 4SPD 4X2 4SPD 4X4GMC Jimmy 1983-1993 4SPD 4X4 4SPD RWDS15 1983-1991 4SPD 4X4 4SPD RWDSafari 1985-1993Sonoma 1991Suburban 1992Oldsmobile Bravada 1991-1992Pontiac Firebird 1983-1993 4SPD RWDParisienne 1983-1988 4SPD RWD Parts ship daily from our distribution center.FREE SHIPPING on US Orders GOT QUESTIONS on your specific Year/Make/Model?
