I have a 1996 dodge ram 1500 with a 5.2 V8 318. When i tow my enclosed trailor 14 foot, Should i turn off the the overdrive button? Last season i have towed with the overdrive off. I did install a trany cooler last year,and heavy adjustable rear leaf springs, heavy duty shocks, load - E - tires, and have the tranny serviced every year -new fluid and filter .Should i keep towing with the O.D. off? What about freeway driving ?And city driving with a trailor? thank you scott.
