I have a friend that is going to move to Arizona from Indiana. He has a 96 G-20 van. It has 5.7 engine and it has all the extra coolers for trans and oil. The van has 9000lb G.V.W. so it is on the heavy duty side of the scale. The trans it has is the 4L80E or option code MT1. We will be towing a car on a trailer to Arizona ( a Mitsubishi 3000) The question is whether we should tow in overdrive or should we tow in 3rd. The owners manual deos not say anything about this. What are some of your opinions. Thanks in advance. Scott
