In vehicles with listed Chrysler transmissions, it is common for the overdrive section to suffer from poor lube oil control, resulting in burnt planetaries and failed bushings. One area of weakness is the intermediate shaft. Shafts are often contaminated and cleaning is difficult as it leaves the shaft unrepairable. The OE plug was generally not removed because replacements were not available or were difficult to find. Sonnax offers intermediate pilot and plug kit 22171-02K to allow the shaft to be cleaned and, equally important, improve lube control. Each kit will service five shafts.

• Sonnax pilot has a smaller orifice, resulting in more lube flow to the bushings and planetaries
• Use of the Sonnax pilot allows the salvage or conversion of early, small-diameter pilot A727 shafts to later, large-diameter applications
• Sonnax end plug allows the shaft to be cleaned, preventing post-rebuild contamination
