In a 5-speed manual transmission, when the vehicle is in 3rd gear, the power flows along a specific path from the engine to the drive wheels. Step 1: Power originates from the engine's crankshaft and is transmitted through the flywheel to the clutch disc. Step 2: When the clutch is engaged, the power then enters the transmission via the input shaft. Step 3: The input shaft has a gear (often called the input gear or constant mesh gear) that is permanently meshed with a corresponding gear on the countershaft (also known as the layshaft). This transfers power from the input shaft to the countershaft. Step 4: The power then travels along the countershaft. The countershaft has several gears fixed to it, including the 3rd gear. Step 5: The 3rd gear on the countershaft meshes with the 3rd gear on the main shaft (or output shaft). This 3rd gear on the main shaft is typically free to rotate on the shaft when not selected. Step 6: When 3rd gear is selected, the 3rd gear synchronizer sleeve slides and locks the 3rd gear on the main shaft to the main shaft itself. This makes the main shaft rotate at the speed of the 3rd gear. Step 7: The power then exits the transmission via the rotating main shaft (output shaft), which connects to the driveshaft, differential, and ultimately the drive wheels. 3 done, 2 left today.
