Drivetrain - transmission, differential axles, those parts responsible for moving the car down the road
Double Clutching - a method of pre-synchronizing engine speed to the next gear you are about to select which reduces wear in the transmission and clutch
Clutch Disc - a friction device that takes up engine torque and transmits it to the transmission
Pressure Plate - a spring-loaded clutch disk clamping device that that allows you to engage/disengage engine from transmission
Release Bearing - a ball bearing that allows your stationary clutch actuator to push the rapidly spinning pressure plate fingers
Cross-Fork - a cable actuated pivoting release bearing pusher
Bowden Tube - a flexible cable guide tube from the chassis to the transaxle that helps dampens out clutch chatter
Wingnut - the clutch pedal freeplay adjuster at the end of the threaded clutch cable
Clutch Chatter - a damaging bounce between the pressure plate and the clutch disk during engagement
Clutch Slip - when pressure plate cannot adequately clamp the clutch disk to the engine > most usually due to extreme wear or contamination
Clutch Sticking - when pressure plate does not release the clutch disk from the engine > very damaging to transmission
Synchronizers - little brass rings that force the transmission gear you select to match the speed of the shaft it's riding on before engagement can take place
Shift Fork - a sliding selector that directs gear engagement in the transmission
Detent - a spring-loaded pin that holds selector in precise position
Hockey Stick - end of shift rod in transmission that selects which fork you want via selector assembly that prevents more than one fork from being engaged at one time
Nose Cone - removeable front of transmission where hockey stick and selector reside
Shift Rod - horizontal rod that transmits your instructions to shift
Shift Lever - vertical rod with the gear shift knob at the top that informs shift rod
Stop Plate - an adjustable floor plate that prevents inadvertent engagement of reverse
Shift Coupler - a noise and vibration absorber as well as a flexible joint between shift rod and transaxle
Shift Rod Bushings - support sleeves at front middle and rear of shift rod traverse
CV Joint - allow independent driveshafts to move up and down while transmitting power by use of precise balls in carefully engineered grooves
Torsion Bar - cross-wise (transverse) spring steel bars that twist axially with input from arms attached to the wheel assemblies > excellent springing choice
Tire vs Wheel - a tire is rubber - a wheel is metal
