Freelander 2 towing advice sought please

Hi andybe, I have a Freelander 2 SD4 HSE auto 2011 and leave it in Drive. It generally stays in 6th but can sometimes hunt between 5/6th depending on speed & inclines. I then slide it over to what you called "sport" and hold it in 6th or 5th depending on the road. Fantastic tow cars and good mpg as well, I love the car. Having had various estate cars, an X1 and a few CRVs it is by far the best for us.
