Shift Kit V/B Repair Kit Jeep/Toyota/Lexus

The TRANSGO Shift Kit V/B Repair Kit (SK 340) is a valve body and bushing repair solution engineered for A340, A341, A343, and AW4 automatic transmissions found in Jeep, Toyota, and Lexus platforms. This kit addresses internal wear and shifting inconsistencies by replacing critical valve body components—valves, bushings, and springs—that deteriorate under normal driving conditions and contribute to transmission lag, harsh shifts, or delayed engagement.

The SK 340 is a targeted repair component, not a full transmission overhaul. Its composition includes OEM-specification bushings and springs that restore original valve bore clearances and spring tension, allowing the solenoid valve system to respond with factory-correct timing and pressure modulation. Technicians working on Toyota and Lexus four-speed automatics—particularly those with mileage-related shift quality degradation—rely on this kit to restore transmission response without complete disassembly. Installation requires valve body removal and familiarity with automatic transmission service procedures, making it a professional-level repair item.

The kit is purpose-built for owners and shops addressing intermittent shift problems, solenoid stick conditions, or worn valve bore components in Jeep models equipped with the AW4 and Toyota/Lexus vehicles running the A-series automatics. It is commonly used as part of preventive maintenance during transmission service or as a targeted fix when shift quality issues emerge without transmission rebuild necessity. At 0.77 lbs and compact dimensions, the kit contains all internal components needed for a single valve body refresh.
