***** Driveline *****

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
