there probably is air in the cooling system or low on coolant. The ac is
shutting off due to the engine control module sees it is overheating. The
transmission is going into a limp mode you also probably have performance
restriction on the dash. When the performance restriction is on the
transmission is limited to gears and the vehicle performance is restricted to
protect its self.
