Symptoms:
  • Gear ratio & solenoid codes
  • No shift
  • Various shift concerns
Cause:

Bore wear prevents proper valve stroke and reduces critical clutch/brake feed/apply oil flow through the various relay/signal valves.

Correction:

Restore proper clutch/brake feed and apply control by reaming bore to match the improved Sonnax oversized valve.

Oversized Two-Spool Relay/Signal Valve Kit

Part No. 15741-49K

  • Valve
  • End Plug

This kit can be used in any of nine locations in three different valve body applications.

Complaint:

  • Gear ratio & solenoid codes
  • No shift
  • Various shift concerns

Cause:

Bore wear prevents proper valve stroke and reduces critical clutch/brake feed/apply oil flow through the various relay/signal valves.


Correction:

Restore proper clutch/brake feed and apply control by reaming bore to match the improved Sonnax oversized valve.

The Aisin AW 6-speed units TF-80SC, TF-81SC and TF-60SN (VW 09G) 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
