I have started to use my 93 FJZ80 to tow my boat. It is not a big boat, under 3000 lbs with trailer. But I am in arizona, where it is hot, and the trip to the lake is pretty much a slow steady climb. It is mostly a highway trip at 55-60 MPH.
My question is, when towing under these circumstances should I turn the overdrive on the tranny off?
My thinking is that turning the O/D off makes life easier on the tranny, but that the higher RPM's could increase engine temperatures. Is that a correct assumption?
On this trip, I turned the O/D off and didn't have any temp problems. The gauge never rose, and the AC never turned off. Given that, I am inclined use this approach---tow with the O/D off, and keep it at moderate speeds. Would you guys agree?
