Oversize Secondary Pressure Regulator Valve Kit* Reamer Required

O/S SECONDARY REG VALVE (A340E/F)

* Reamer Required - No Longer available

Fits '00-Later V6 & V8, late models, Type 3 & 4 valve bodies.

Symptoms:

  • TCC apply & release concerns
  • Burnt TCC apply components
  • Overheated transmission
  • Bushing wear

Cause:
Oscillation of the steel secondary pressure regulator valve within the aluminum casting causes wear, which will allow converter feed oil to leak to exhaust and not supply the lube circuit, resulting in converter complaints, burnt apply components and lube related failures.

Correction:
Restore proper hydraulic control by refurbishing the bore and replacing worn components with Sonnax oversized secondary pressure regulator valve kit.


The secondary pressure regulator valve in Toyota A340E and A340F late units receives regulated line fluid pressure from the main pressure regulator valve, and routes it to the converter and lubrication circuits. The continual oscillation of the steel valve within the aluminum casting creates wear, allowing this valuable fluid pressure to exhaust, resulting in converter complaints, burnt apply components and lube-related failures. The Sonnax oversized secondary pressure regulator valve kit restores proper hydraulic clearance in a refurbished bore and includes an O-ringed end plug to positively seal the balance pressure circuit.

  • Hardcoat anodized valve combats premature wear
  • O-Ringed end plug positively seals the balance pressure circuit

Content:

  • Valve
