The Reprogramming Kit A340/341/343/AW4 from TransGo is a professional-grade transmission recalibration solution designed for mechanics and serious enthusiasts working with Toyota, Lexus, and Jeep four-speed automatic transmissions. This kit addresses shift quality, pressure mapping, and torque converter lockup timing—critical factors that separate a stock transmission from a properly dialed-in unit.
TransGo's A340/341/343/AW4 reprogramming kit works by recalibrating internal transmission maps—shift points, line pressure curves, and solenoid timing—to restore OEM performance standards or adapt to engine modifications. Installation requires transmission removal and internal access, making it a comprehensive recalibration that improves shift characteristics, reduces hunting between gears, and optimizes converter engagement for smoother power delivery and improved fuel economy.
Professional transmission technicians, rebuild shops, and long-haul mechanics benefit from this kit, as it is engineered around proven transaxle architecture used across multiple platforms. It is compatible with A340E, A341E, A343F variants found in Toyota Camry, Lexus ES, and Jeep Grand Cherokee applications, making it a versatile choice for various vehicle models.
