- Sonnax Throttle Valve Kit
Common complaints with listed Chrysler units are shift timing concerns, throttle buzz, poor kickdown and/or early upshifts caused by valve and sleeve wear. The OE aluminum throttle plunger stem wears from contacting the steel linkage pivot. Damage to the end of the throttle plunger creates a side load that binds the plunger and restricts the movement of the throttle valve. Plunger side loading also damages the sleeve that guides the plunger. The sleeve wears as a result of the side load and creates leakage of detent pressure. Loss of detent pressure reduces kickdown that should occur during wide-open throttle (WOT). The Sonnax throttle valve kit eliminates side loading and restores throttle valve control.
