Product Description

41TE, 42LE, 42RLE, 45RFE, 545RFE, 62TE, 68RFE

Oversized Solenoid Switch Valve
Part No. 92835-21

Fits bores containing OE switch valve with .420" dia. large spool only.

Tooling: 

• F-92835-TL
• VB-FIX

Warning: Measure large spool diameter on OE switch valve as shown here to verify which Sonnax part will fit the unit being repaired. Chrysler switch valves measure .420" or .453". Sonnax offers repairs for both these versions.

Solenoid switch valves and plugs in listed Chrysler transmissions cause bore wear as they oscillate and stroke during operation. This wear allows pressure loss and cross-leakage, and often permits the plugs to cock and hang up in the bore. This can result in failsafe mode, various codes, bind-ups, and burnt 4th or overdrive clutches. In 41 and 42 series units, TCC concerns can result, including engine stalling due to improper lockup. Reconditioning the bore and installing patented Sonnax oversized solenoid switch valve kit 92835-21 restores vital clearances for renewed operation and control.

• Annular grooves help center valve in bore to prevent future side-load wear
• Hardcoat anodized aluminum valve combats premature wear

To maintain proper hydraulic ratios, it is highly recommended that this valve be installed along with the Sonnax oversized switch valve end plug kit 92835-18K. 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. Optionally, F-92835-TL32 will ream both parts of the bore in one step.

Symptoms:

• 4th Clutch burned
• Bind-up
• Codes 841, 868, 871, 988, 1775, 1776
• Engine stall (41 & 42 series)
• Failsafe mode
• No lockup (41 & 42 series)
• OD clutch burned
• TCC apply & release concerns (41 & 42 series)

Cause:

Excess bore wear at the solenoid switch valve circuit allows critical pressure loss.

Correction:

Recover hydraulic control and prevent valve sticking by reconditioning the bore and installing Sonnax oversized solenoid switch valve.
