All too often, performance street enthusiasts place emphasis on potential engine problems while critical transmission functions go unnoticed. Available for performance GM 4L60E/4L65E/4L70E/4L80E/4L85E applications, the new Shift Boss Transmission Programmer from TCI® is designed to ensure desired shift firmness while also monitoring the two most critical drivetrain functions - temperature and transmission line pressure.
The Shift Boss features three unique shift mode choices - Stock for OEM shift characteristics, Stage 1 for firm solid shifts and Stage 2 for hard strip shifts. You can monitor transmission temperature or pressure by simply depressing the display button. Simple-to-use and easy-to-install, this performance programmer can be considered an inexpensive, easy-to-install shift improver, and temperature/pressure monitor for your transmission.
This handheld unit includes a digital screen with selection options for transmission temperature, shift psi and all three shift modes.
