68RFE

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

Tool Required

Symptoms:

• 4^th 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.

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 the patented Sonnax oversized solenoid switch valve kit 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
