The 1990 Mack CH600 equipped with an E7 engine typically comes with a Mack 10-speed transmission, commonly the Mack T2070 or T2090 model. This transmission is designed to handle the power output of the E7 engine, providing efficient torque management and smooth shifting for heavy-duty applications. Some configurations may also include other transmission options like the Mack 13-speed, depending on the specific truck setup and intended use. Always consult the owner's manual or manufacturer specifications for precise details.
