68RFE

Symptoms:

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

Cause:
Bore wear at solenoid switch valve plugs allows critical pressure loss and causes plugs to hang up in the bore.

Correction:
Recover hydraulic control and prevent valve sticking by installing the patented Sonnax solenoid switch valve plug kit.

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

Solenoid switch valve 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. Installing the patented Sonnax solenoid switch valve plug kit restores normal operation and control to this circuit.

• Patented Sonnax plugs redesigned to prevent cocking
• Annular grooves help center plugs in bore to prevent future side-load wear

Kit Contains:

• Inner Plug
• Outer Plug
