A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. [1] [2] Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable ...
In December 2020, GM initiated a program to repair or replace 9T65 transmissions which were causing issues. Repairs were limited to external components only. [12] The program applied to vehicles that had less than 18,000 mi (29,000 km) and had been delivered within the past 18 months. [13]

In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception. [1] The intermediate frequency is created by mixing the carrier signal with a local oscillator signal in a process called heterodyning , resulting in a signal at the ...
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...

Maintaining an efficient speed is an important factor in fuel efficiency. [9] [10] Optimal efficiency can be expected while cruising at a steady speed and with the transmission in the highest gear (see Choice of gear, below). The optimal speed varies with the type of vehicle, although it is usually reported to be between 35 and 50 mph (56 and ...
