Removing and installing a transmission is the same for all rear-wheel-drive vehicles, with a few minor exceptions. Some, not all, early model transmissions have a kick-down cable on the right side of the transmission, that is attached to the throttle linkage. This was virtually eliminated on late-model vehicles. Late-model transmissions will have electrical connectors for the speed sensor and neutral safety switch. This is not a job for the inexperienced. It is slightly technical and the parts are heavy enough to be dangerous if not done properly.

In an internal combustion engine, a mix of fuel and air is ignited by a spark provided by spark plugs. The ignition takes place inside a combustion chamber called a cylinder. The resultant force pushes the piston out of the end of the cylinder and provides mechanical energy to the engine. The transmission is the portion of the automobile that transfers the power of the engine to the drive shaft. Engaging the gears in the transmission allows the car to move, and disengaging the transmission allows the car to run without moving, also known as idling.

When the car has different speed or load requirements, it has different power needs. If the car only had one gear available, it would require the most power available, which is not compatible with many situations.The car cannot perform as well without being in the correct gear, aligning the correct gear configuration with the needs of the car. To perform with the most efficiency, there must be multiple configurations available. Automatic transmissions accomplish this process without the need for interaction on the part of the driver.

A manual shift transmission uses different gears to provide different levels of power; each set of gears is engaged when the gearshift is shifted. An automatic shift transmission uses a planetary model gear configuration. In a planetary model gear configuration, the same group of gears is used for each level of power, but they are placed in different combinations to achieve the desired result.
