Sonnax Throttle Valve Plunger Kits

5.0 out of 5 stars 3 Customer Reviews

Sonnax throttle valve plunger kits address the poor line rise or no detent downshifts that can be common complaints in vehicles with a stock overdrive transmission.

Sonnax throttle valve plunger kits address the poor line rise or no detent downshifts that can be common complaints in vehicles with a stock overdrive transmission. The steel plunger continuously reciprocates within the aluminum sleeve, wearing out the sleeve. This wear (plus the weak OE spring) allows throttle valve feed oil to leak past the plunger and exhaust, resulting in the aforementioned issues that can lead to 3-4 clutch failure. Sonnax throttle valve plunger kits include an improved throttle valve spring designed to properly maintain higher line pressure and improved throttle valve performance. Order the kit
