Hydraulics and fluid flow
This pump supplies hydraulic pressure for the transmission.
What is the front pump (or oil pump)?
The three main parts of a planetary gear set.
What are the sun gear, planet carrier, and ring gear?
The section of the converter connected to the engine.
What is the impeller/pump?
The computer that controls modern transmissions.
What is the TCM (or PCM in some vehicles)?
The word "Diploma" starts with this letter.
What is the letter "D".
The type of hydraulic valve that directs fluid to apply or release components.
What is a spool valve?
Holding this component typically creates reverse.
What is the planet carrier (in many designs)?
This part multiplies torque during acceleration.
What is the stator?
These units adjust hydraulic pressure using electrical signals.
What are solenoids?
The word "Jolly" starts with this letter.
What is the letter "J".
This device controls pressure rise based on engine load.
What is a pressure regulator or throttle valve?
Gear ratio is increased when this component is held stationary.
What is the sun gear?
This clutch improves fuel economy at cruise.
What is the torque converter clutch (TCC)?
This sensor monitors throttle opening and load.
What is the TPS?
The word "Bee" starts with this letter
What is the letter "B".
This passageway allows fluid pressure to engage a clutch pack.
What is an apply circuit?
An overdrive condition happens when this part becomes the output.
What is the sun gear or carrier (depending on design)?
The fluid-coupling condition where engine speed is much higher than turbine speed.
What is stall?
This sensor detects rotational input speed.
What is the input speed sensor?
The word "For" starts with this letter.
What is the letter "F".
The law that explains how fluid transmits force in a sealed system.
What is Pascal’s Law?
When two components of a planetary set spin at the same speed, this occurs.
What is direct drive?
The ratio of impeller speed to turbine speed during coupling.
What is the coupling ratio?
When the TCM modulates pressure for smoother shifts, this is called ____.
What is adaptive shift control?
The word "Simon" start with the letter.
What is the letter "S".
