Towing - Which gear??
I am very new at this, so please bare with me. I have a 2006 Toyota Sienna with AT and an external transmission cooler towing a 2015 Coachman Clipper - dry GVW 2,855 lbs. Max tow weight is 3,500 lbs.
The Toyota owners' manual says not to tow in 'D', but it does not say why or which gear I should use.
My options are 1, 2, 3 or 4. D is apparently an overdrive gear??
Any suggestions and why?
