Sonnax 22771-09 Manual Valve for Chrysler Automatic Transmissions

The Sonnax 22771-09 manual valve introduces converter and cooler charge in Park for various Chrysler automatic transmissions, addressing a critical design flaw in the OE valve. Many Chrysler transmissions suffer from delayed engagement, converter bushing failure, overheated converters, and dragging Forward clutches due to the OE manual valve design that does not allow converter or cooler charge in Park.

Key Features:

• Engineered to overcome OE shortcomings by allowing fluid into critical circuits when in Park
• Case-hardened steel valve combats premature wear
• No valve body modifications necessary
• No reaming or special tools required
• Will not cause forward clutch to drag in Park
• Patented design (Patent No. 6,689,007)

Compatible Transmissions:

• 42RE / 42RH / 46RE / 46RH / 47RE / 47RH / 48RE
• A727 (TF8) / A904 (TF6)
• A500 / A518 / A618

For maximum benefit, installing Sonnax lube-regulated pressure regulator valve 22771A-02K along with this manual valve is recommended. This drop-in Zip Valve installs quickly and easily, providing an effective solution to converter and cooler starvation issues in Chrysler rear-wheel-drive transmissions.

Application Note: Compatible with 1978 and later pressure regulator valve designs. Not compatible with 1977 and earlier pressure regulator valve styles.
