Product Description
AS66RC RE6R01A Oversized Secondary Pressure Regulator Valve Kit
Sonnax Part Number: 122740-24K
Tooling Required
- F-122740-TL24
- VB-FIX
The secondary pressure regulator valve on the Aisin Seiki AS66RC and Nissan RE6R01A transmissions can often wear out. Deterioration at the balance spool end allows for fluid loss resulting in high line pressure, harsh shifts and overheating due to reduced cooler/converter flow. Wear in the boost sleeve can result in converter pressure bleeding into the EPC.
Restore proper hydraulic integrity of the circuit by reconditioning the bore and installing Sonnax oversized secondary pressure regulator valve kit 122740-24K.
- Hardcoat anodized aluminum valve combats premature wear
- Highly wear-resistant boost valve sleeve increases life of part
- Oversized valve maintains OE pressures
PACKAGE CONTAINS
- Secondary Pressure Regulator Valve
- Boost Valve
- Boost Sleeve
- Spring
SYMPTOMS
- TCC codes
- Converter shudder
- Overheated fluid, bushings & converter
- Low SLT pressure
CAUSE
Bore wear at the balance end of the valve reduces converter and lube flow. Boost sleeve wear results in converter pressure bleeding into and elevating EPC. Bore wear at the spring end of the valve allows the SLT circuit and regulated converter pressure to cross-leak.
CORRECTION
Sonnax oversized secondary pressure regulator valve kit corrects circuit pressure loss and restores control over the secondary pressure regulator valve and boost valve function.
