I have a brand new the Platinum MAX with the heavy duty towing option. What is the forum consensus recommendation for the first oil and filter change? I know the manufacturer says 10000 miles, but there must be contaminants and other metal pieces floating around in the oil after the 1000 mile break-in period. Also, the same question for the transmission. The manual says not to haul my horse trailer until the car has 1000 miles on it. When I start to haul (5000lbs about 4 times a month, 2 hours each way) I believe I should have the transmission oil changed as well. I am thinking maybe after 1000 miles of hauling? Does this vehicle have a transmission oil cooler? Thanks for your help!!!
