Symptoms:
  • Burnt clutches
  • Erratic shift timing
  • Failsafe mode
  • Harsh shifts
  • Overheated fluid
  • Ratio codes
  • Slipping
  • Soft shifts
Cause:

Excess wear in various bores allows pressure loss that causes driveability concerns.

Correction:

Recover hydraulic control and restore normal shift operation by reconditioning the bore and installing Sonnax oversized clutch cutoff valve.

Oversized Clutch Cutoff Valve

Part No. 15741-63K

  • Valve
  • End Plug

Fits 9 separate locations; see note below.

Complaint:

  • Burnt clutches
  • Erratic shift timing
  • Failsafe mode
  • Harsh shifts
  • Overheated fluid
  • Ratio codes
  • Slipping
  • Soft shifts

Cause:

Excess wear in various bores allows pressure loss that causes driveability concerns.


Correction:

Recover hydraulic control and restore normal shift operation by reconditioning the bore and installing Sonnax oversized clutch cutoff valve.

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.

  • Hardcoat anodized aluminum valve combats premature wear
  • Annular grooves help center valve in bore to reduce future side-load deterioration
NOTE:

For TF-60SN, 09G, 09K, 09M, 6F21WA: Fits 3-4 transition bore, K3 relay bore & 4-5 timing bore.
For TF-80SC: Fits C1 shift bore, B1/C3 control bore & shift valve bore.
For TF-81SC: Fits C3 signal bore, C1 shift bore & B1/C3 control bore.
