The short answer is yes, a car can start with a bad transmission. The transmissions primary function is to transfer power from the engine to the wheels, allowing the car to move. The starting process, however, primarily involves the engines ignition system, not the transmission.
How a Car Starts
When you turn the key or press the start button, the starter motor engages, turning the engine crankshaft. This, in turn, causes the pistons to move, creating combustion and generating power. The transmission is not involved in this initial process.
