Alas automatic gearboxes have passed their reliability plateau imho . The old torque converter 4 speed hydraulic controlled boxes were pretty bullet-proof if the fluid+filter was changed regularly. Now in the search for fuel economy a new generation of gearboxes have arrived be it CVT or automated clutch or preselect twin clutch DSG type boxes. These depend far more on electronics and servos to select gears and these seem to be more prone to failure than the older less efficient boxes. Sophistication has its price perhaps ??
