Why would an automatic stall?

Most automatic cars have an oxygen sensor that keeps track of the oxygen levels in the air that is pushed out. Occasionally this sensor stops working properly and the vehicle is unable to determine that enough oxygen is available for combustion, so it stalls the engine.

What is the most common cause of automatic transmission failure?

At the top of all auto repair experts lists for causes of problematic transmissions is low transmission fluid. Usually caused by a leak somewhere in the system, low or contaminated fluid makes it nearly impossible for the transmission to automatically shift gears and run smoothly.

It smoothly glides between the first and second and vice versa, but it just stays in second when you try to push it to the third. In that case, the catalytic converter can touch the side of the valve body area, overheating the transmission and creating metal shavings in the pan. Take immediate action when facing problems with shifting gears.
