Description
42RE / 44RE / 46RE / 47RE / 48RE / A727 / A904 Heavy Duty Throttle Valve Kit, Sonnax 22771-HDK3.
Fits all Chrysler RWD models, including ’05-later units with motorized linkage.
The TV bore wears out easily in listed Chrysler RWD transmissions, with the 48RE seeing much higher rates of poor line pressure rise and inconsistent shift timing compared to earlier units.Sonnax heavy duty throttle valve kit 22771-HDK3 is ideal for earlier, wide-open throttle shift points in new or lightly used valve bodies. The modified valve reduces gear hunting and the need to back off the throttle when shifting under heavy load. An optional balance spring improves throttle control if the bore shows minimal wear.
