Relay signal valve TF60, TF80

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

 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.

Spring adjuster kit TF60, TF80

In Aisin AW TF-60SN, TF-80SC and TF-81SC applications the oil circuit between the clutch control valve and the adjuster is clutch apply oil. The clutch apply oil opposes the solenoid oil and slows the stroke of the valve in response to clutch fill rate. When the adjuster leaks, both clutch oil and fill rate are affected. Installing the Sonnax spring adjuster kit 15741-48K results in shorter, firmer shifts and less variance across temperature range.

Clutch cutoff valve TF60, TF80

Fits 9 separate locations; see note below.

Clutch cutoff valves in listed Aisin AW, BMW and VW/Audi transmissions are responsible for switching or relaying control pressure in their respective circuits. Over time, bore deterioration allows pressure loss that negatively affects circuit function.

Depending on which bore is influenced, this can result in shift timing issues, harsh or soft shifts, burnt clutches, overheated fluid, and failsafe mode. Reconditioning the bore and installing Sonnax oversized clutch cutoff valve 15741-63K eliminates excess wear for revived shift control in all ranges.
