Heavy Duty Throttle Valve Kit
Part No. 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.
- Restores and extends line pressure response and shift timing in new/lightly-used units
- Hardened steel plunger and valve increase durability, especially in 48REs
- Optional shims and TV spring for custom TV pressure adjustment and tuning
