27C hot? Our vacations often takes us to Las Vegas, where temperature in shade exceed 40C, while open parking lots or desert can reach 60C.
MB do have transmission coolers build into main radiator. Besides the flex hoses deterioration at about 15 years mark, never had a problem.
Cold transmission is not a good thing. The reason for the trany cooling element build into radiator is to warm it up on cold days as well.
