D4D has it pretty right, except for the part about reliability which should be brand qualified. Most of the members on this forum appear to drive patrols or utes, so their statements would be true when looking at the auto options available for those styles of vehicles. However, if you want a wagon then the auto is a far better option. In the case of Discovery or Cruiser 200 there is no manual option. If they have a transmission oil cooler fitted and are serviced properly should be no problem ( unless it's made by Jeep)
