🧠 This maze of channels is basically the hydraulic brain of an old-school automatic transmission, using pressurized oil to decide when and how the car shifts.
⠀
The part is called a valve body, and transmission fluid is pumped through its intricate passages toward different valves, clutches and bands.
⠀
In older automatics, changes in vehicle speed and engine load altered hydraulic pressures, physically moving shift valves and routing fluid to the correct clutch circuits.
⠀
Those clutches then lock or release different parts of the planetary gearsets, which is how the transmission creates multiple gear ratios without you touching a clutch pedal.
⠀
So the “hydraulic calculus” joke is surprisingly accurate, because before computers took over much of the decision-making, automatics were essentially using fluid pressure, springs, valves and carefully sized passages to perform mechanical logic.
⠀
Modern transmissions still use hydraulic pressure to apply their clutches, but electronic solenoids and control modules now decide where much of that pressure goes.
⠀
Is this one of the coolest examples of engineers solving a problem mechanically before computers could do it?
