Symptoms:

  • Low cooler flow idling in gear
  • Overheated converter fluid
  • TCC codes
  • TCC lining failure

Cause:

The main pressure regulator valve allows limited fluid to flow to the converter and cooler. The limited flow of charge oil crossing in front of the TCC piston allows the clutch to drag, creating overheat condition.

Correction:

Ensure sufficient converter charge flow by installing Sonnax drop-in converter charge regulated pressure regulator valve.

Warning:

The OE valve spool diameters should be measured the verify application. The Sonnax valve will replace the OE valve matching these measurements

Honda/Acura models equipped with a 4-speed, 3-shaft and 5-speed transmission may overheat the converter. Insufficient flow to the TCC release circuit at low RPM allows the lockup piston to drag on the cover, generating heat. This heat glazes the TCC lining and overheats the fluid. Eventually the slip rate cannot be controlled due to lining failure resulting in code P0740. To prevent this problem, Sonnax offers a drop-in converter charge regulated pressure regulator valve 98892-04K. This valve allows more flow to the converter and cooler circuits, increasing converter charge during low pump output conditions, and includes an internal checkball to prevent converter drain back when the vehicle is off. The same valve design will assist converter charge and TCC apply pressure during low-output/high-load demand situations.

Make sure to inspect and replace lockup control valve endplugs with Sonnax O-ringed end plug kit 98892-01K to help ensure maximum TCC apply pressure.

  • Maintains adequate converter charge and cooler flow at low RPM
  • Checkball inside valve prevents converter drain back when vehicle is shut off
  • Drop-in Zip Valve™ installs quickly and easily

This kit fits various Honda/Acura 4-speed, 3-shaft and 5-speed models. However, model to model, the appearance of valve bodies and the location of the pressure regulator valve bore may vary. The MAXA 98-02, 2.3L Accord model is illustrated here.

This kit fits 4/5 speed Honda/Acuras except: A6VA, AOYA, BOYA, MPOA, MPJA, APXA, MPXA, MP1A, PX4B, MPRA, RO, MPZA, M5HA, M1WA, M5DA, MPWA, MPYA.

This product will NOT correct a worn valve or pump body. It is recommended that pressure regulator bore wear, pump gear clearances and end plug leakage be checked prior to installation for best results. Use oversized kit 98892-13K if restoring a worn valve or pump body.
