Technical issues and repair guidelines
This gearbox 3L80 has a simple and reliable design. All parts are made of solid materials. Shifting of gears is implemented very smoothly and almost unnoticeable. The main disadvantages of this automatic transmission are significant dimensions and weight of the transmission. This transmission is considered to be the most reliable in the history of GM (the most enduring).
