What is the disassembly and assembly method of an automatic transmission?
1 Answers
Automatic transmission disassembly and assembly steps are as follows: First, remove the front and rear housings, oil pan, and valve body of the automatic transmission, then disassemble the oil pump assembly; dismantle the planetary gear transmission. After removing the parts, clean them with gasoline, and install them in the reverse order of disassembly. Extension: Compared to manual transmissions, automatic transmissions differ significantly in structure and operation. Manual transmissions primarily change gears by adjusting different gear combinations, whereas automatic transmissions achieve gear shifting through hydraulic power transmission and gear combinations. The torque converter is the most distinctive component of an automatic transmission, consisting of a pump wheel, turbine, and guide wheel. The pump wheel and turbine form a working pair, with the pump wheel driving the turbine to rotate via fluid. The guide wheel between the pump wheel and turbine creates a speed difference between them through reaction force, enabling gear shifting and torque conversion. For the driver, simply pressing the pedal with varying force allows the transmission to automatically shift gears up or down.
