In an automatic transmission, what does the shift lever connect to?

In an automatic transmission, the shift lever primarily connects to the manual valve. This manual valve is critical because it directs the flow of transmission fluid to various components within the transmission based on the driver's selection of gears. When the driver shifts the lever, it actuates the manual valve, which subsequently controls how the transmission fluid is routed to either engage or disengage different gears, ultimately affecting the vehicle's speed and power delivery.

The function of the manual valve is to determine the appropriate hydraulic pressure needed to engage the desired gear, which makes it a key component in the transmission's operation. It is essential for translating the driver's input into the mechanical actions necessary for changing gears smoothly. The direct connection between the shift lever and manual valve ensures that the vehicle behaves in a predictable manner according to the driver's intentions, thereby providing a seamless driving experience.
