Symptoms:

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

Cause:

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

Correction:

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

The listed Aisin AW, VW/Audi and Mini transmissions each utilize three spool valves as relay, control or switch valves. These valves are found in multiple circuits in all valve bodies across this family of units (see Figures 1-4) and are used to route critical clutch/brake feed and apply oil to the appropriate apply components. The numerous shift/drivability complaints vary depending on the circuit affected. Sonnax oversized three-spool relay/control/switch valve kit 15741-50K 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 six locations in listed applications
  • Valve is hardcoat anodized to reduce wear
  • Annular grooves improve lubrication and valve centering
  • Valve
  • End Plug

Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
NOTE: The vacuum test for the B1/C3 Relay Port in TF-81SC application is an example of a typical port location. All the other valves should be checked similarly at the port associated with the plug-to-valve spool interface.
