The listed Aisin AW 6-speed units each utilize two-spool valves as relay or signal valves. These valves are found in multiple circuits in all valve bodies across the AW6 family and are used to route critical clutch/brake feed and apply oil to the appropriate apply components. Various shift concerns can accompany ratio or solenoid codes when bore wear becomes a problem in this circuit. The oversized two-spool relay/signal valve kit 15741-49K restores proper clutch/brake feed and apply pressure to the related components by functioning in a refurbished bore that provides correct hydraulic clearances.

• Fits any of nine locations in several Aisin AW 6-speed applications
• Valve is hardcoat anodized to reduce wear
• Annular grooves improve lubrication and valve centering
