Sonnax 92835-21 Oversized Solenoid Switch Valve for Chrysler Transmissions

The Sonnax 92835-21 oversized solenoid switch valve is designed to recover hydraulic control and prevent valve sticking in various Chrysler transmissions. Solenoid switch valves in listed Chrysler transmissions cause bore wear as they oscillate and stroke during operation, allowing pressure loss and cross-leakage, often permitting the plugs to cock and hang up in the bore, which can result in failsafe mode, various codes, bind-ups, and burnt 4th or overdrive clutches.

Key Features:

• Hardcoat anodized aluminum valve combats premature wear
• Annular grooves help center valve in bore to prevent future side-load wear
• Restores vital clearances for renewed operation and control
• Precision-engineered for bores containing OE switch valve with .420" diameter large spool

Installation Requirements:

• The bore for the switch valve end plugs must be reamed with F-92835-TL18 prior to reaming the solenoid switch valve bore with F-92835-TL
• Requires VB-FIX self-aligning valve body reaming fixture
• It is highly recommended that this valve be installed along with the Sonnax oversized switch valve end plug kit 92835-18K to maintain proper hydraulic ratios

This oversized solenoid switch valve fits 45RFE (1999-2018), 68RFE (2007-2018), 5-45RFE (1999-2018), and DND (2006-2018) transmissions. In 41 and 42 series units, TCC concerns can result, including engine stalling due to improper lockup.
