Description & Specs
Vehicles with Toyota/Lexus U660E and U660F transmissions may exhibit 2nd and 6th Gear shift complaints and a burned B1 brake. These problems may be caused by continuous oscillation of the steel B1 apply boost valve within the cast aluminum boost sleeve, creating excessive wear and a path for line pressure to exhaust and the B1 apply control valve to stroke prematurely. Sonnax B1 apply boost valve kit S47741HK 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
