Zip Kit for Toyota/Lexus UA80E/UB80E Transmissions

The Sonnax Zip Kit UA80E-UB80E-ZIP is engineered to resolve common transmission complaints in Toyota/Lexus UA80E, UA80F, UB80E, and UB80F models. It specifically targets pressure losses within critical circuits, including main line, clutch apply control, and lockup control. By sealing these areas, the kit helps to rectify symptoms such as delayed engagement, poor shift quality, pressure loss, burnt clutches, overheating, low converter and lube flow, and loss of shift solenoid control pressure. This kit contains uniquely designed, drop-in parts that address the root causes of valve body issues without requiring special tools or reaming. A detailed technical booklet is included, providing in-depth rebuild and inspection tips, along with vacuum testing information for various valve body locations. The UA80E-UB80E-ZIP kit includes components such as a C1 Apply Boost Valve Kit, C4 Apply Boost Valve Kit, Forward/Reverse Accumulator Piston Kits, an O-Ringed End Plug Kit, TCCRV & TCCV Damper Kit, Solenoid Damper Kits, and a Modified Lube Flow Control Valve Kit. These parts work together to recover hydraulic control and restore normal shift operation, extending the vehicle's shift quality.
