Transmission Parts Chrysler Valve Body Valve / Sleeve

Symptoms:

Shift timing concerns
Throttle buzz
Poor kickdown
2-3 Late
3-2 Oversensitive

Cause:

Wear at the inboard/balance circuit causes high throttle pressure and late upshifts. Wear of the OE valve or the bore at the V metering groove circuit causes sensitive 2-3, 3-2 shift timing. Wear at the sleeve area reduces throttle pressure and causes early shifts.

Correction:

The Sonnax oversized valve and plunger restore proper clearances to prevent cross leaking and throttle buzz. The Sonnax design allows this kit to be used in both early- and late-style units.

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. Ideal for bores with moderate to severe wear, Sonnax oversized throttle valve kit 22771-04K fully restores throttle control and prevents future wear.

Repairs moderate to severe bore wear
Hardened steel plunger and valve increase durability, especially in 48REs
Optional shims and TV spring for custom TV pressure adjustment and tuning

Oversized Valve Kit 22771-04K	Fully restores throttle control in bores with moderate to severe wear. Requires tool kit F-22771-TL and the VB-FIX reaming fixture.
Heavy Duty Valve Kit 22771-HDK3	• Ideal for earlier, wide-open throttle shift points in new/lightly used valve bodies. • Reduces gear hunting and the need to back off the throttle when shifting under heavy load. • Optional balance spring improves throttle control if bore shows minimal wear.
Throttle Valve Kit 22771-03K	Basic durability enhancement with an optional balance spring to help revive throttle control in bores with minimal wear.
