It is impractical and practically impossible to convert a manual transmission to an automatic transmission.
Automatic transmissions are complex machines that require special components such as a torque converter, planetary gearbox and electronic control unit to operate. Installing an automatic transmission in a manual transmission vehicle will require significant modifications to the vehicle’s design, including modifications to the engine management system, transmission tunnel, and cooling system.
It is worth considering that the cost and complexity of converting a manual transmission to an automatic will significantly exceed the cost and ease of installing a new automatic transmission.
