Transmission Parts Chrysler Valve Body Valve / Sleeve

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.

Warning:

Measure large spool diameter on OE switch valve as shown here to verify which Sonnax part will fit the unit being repaired. Some Chrysler switch valves measure .420" dia. and others .453" dia. Another third version found in “late” anodized valve bodies have a .453" dia. but with a narrower spool and incorporates an ID groove. Sonnax offers repairs for all three sizes.

Part	OE Large Spool Dia.	Part No.	Tool Required
Standard-size kits address low to moderate bore wear. Oversize kits address excessive bore wear.

Valve body reaming fixture VB-FIX required. These oversized valve kits and their associated tool kits are still available. However, for improved reaming experience, results, and ease of use, it is recommended that oversized valve kit 92835-32K and associated tool kit F-92835-TL32 be used instead.

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

Note

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.
