High Performance Manual Transmissions

A manual transmission works by using a clutch to connect power from the engine flywheel to the transmission input shaft. A release bearing is engaged/disengaged via driver input from a clutch pedal. When the clutch pedal is depressed, the transmission behaves as though it is in neutral until the pedal is released. Releasing the clutch pedal causes the clutch disc to grab the flywheel, which then begins to spin the transmission input shaft and causes the vehicle to move. Typically, vehicles with manual transmissions begin in 1st gear from driver input, by moving the shifter into the appropriate position. When engine RPMs are high enough to engage another gear in order to increase speed or acceleration, the clutch pedal is depressed, the next gear is selected on the shifter, and the clutch pedal is released to allow for more speed with a higher gear ratio. When downshifting to a lower gear to slow down, the same process of pressing the clutch pedal, selecting the gear, and releasing the clutch pedal is needed.

To help determine the manual transmission you have, the first thing to do is confirm if the transmission type you have is original to the vehicle. This can be done by looking at the transmission or taking pictures of it and then researching online what the original type of transmission was that came from the factory. You can then compare physical features to confirm if the type of transmission you have is original. If the transmission you have is not original to the vehicle, you will need to look for identifying numbers stamped on the transmission and research online to find a match.

Manual transmission fluid level is checked via the fill plug on the side of the case, typically located on the top half. When removing the fill plug the transmission is at the correct level when fluid reaches the bottom of the fill plug hole.

An automatic transmission uses a torque converter, which is spun up to a predetermined engine RPM and engages the transmission input shift, causing the vehicle to move. At lower engine RPMs, the torque converter slips enough not to bog the engine down and cause it to stop. A manual transmission uses a clutch instead of a torque converter. This requires driver input by pressing the clutch pedal, putting the transmission into gear, and releasing the clutch pedal, which engages the engine flywheel and connects it to the transmission input shaft. Automatic transmissions are designed to automatically shift into a higher or lower gear based on vehicle speed or transmission fluid pressure. Manual transmissions require driver input to move up or down in gear.
