Product Description
U660E U660F U760E U760F Lockup Control Boost Valve Kit
No tooling required
Vehicles with listed Toyota/Lexus transmissions may exhibit converter apply/release complaints, slip codes, overheated fluid or a burned converter. These problems may be caused by continuous oscillation of the steel lockup control boost valve within the cast aluminum boost sleeve, creating excessive wear and a path for converter/cooler fluid to exhaust and the lockup control valve to stroke prematurely.
Sonnax lockup control boost valve kit 47740-06K has upgraded materials and minimal clearances to prevent wear and restore proper hydraulic control.
- Boost sleeve is manufactured from highly wear-resistant billet aluminum to prevent excessive wear
- Restores proper line rise
- Drop-in Zip Valve™ parts install quickly and easily
Symptoms
- TCC apply & release concerns

Cause
