2:1
2:2
1:4
1:1
When mated gears are NOT the same size, if torque increases:
Speed increases
Speed reduces
The diff is broken
The torque converter is damaged

More torque is required
No torque is required
Its called a crawler gear

Opendrive
A clutch disc:
Provides method of power transfer between the flex plate and input shaft.
acts as a brake for the transmission.
Provides method of power transfer between the flywheel and input shaft
is very durable and resistant to damage from insufficient force from the pressure plate.
A flywheel that shows cracking and hotspots (bluing):
is still serviceable
is getting old
absorbed too much heat from the engine
Has likely had a clutch slipping against it too often/too long
The clutch fork actuator system may be a direct mechanical system or:
pneumatic
hydraulic
electrical
solid state

clutch release bearing
the flywheel
a pressure plate
clutch fork
