    After 244,000 + miles on my 91 Chevy S10 P/U I finally burnt it up
    (Water pump leak). I purchased a 2001 Dodge Ram 1500 with V8
    engine and auto. transmission. The tranny is equipped with overdrive. There was no owners manual in the truck when purchased. My question is do I use O/D when towing a trailer?
    I currently pull a 5 X 8 open trailer loaded with equipment and 2
    extra storage boxes loaded with spare parts, hand tools, fluids, etc. I have not owned a truck with O/D before so this is new to me. Any help will be appreciated.

    When using my F-250 for towing, the owners manual says to turn the overdrive off.

    Both my 95' and 02' pickups (owners manuals) stated that while towing, don't use overdrive. My friend always towed in overdrive on his 97' and guess what happened- transmission problems!

    agreed...turn it off...besides, when towing the thing will always be shifting even on a slight incline if you dont turn it off

    towing in overdrive is fine as long as the tranny temp stays down and you're not lugging it. i'd recommend a temp guage. the dodge transmissions line pressure is controlled by throttle position and what the pump can put out based on rpm (the more rpms, the more pressure that pump can put out as long as your foot is into it).

    dont pull in overdrive unless you know what you're doing. ie: can feel the gear its in, stress being put on the gear, should be in a lower gear ratio. just keep it out of overdrive.

    The others are giving you sound advice. A Dodge 1500 has a very touchy overdrive due to the torque converter lock-up feature. Keep overdrive off for towing and (if you have 3:55 axle ratios) keep it off for back road driving. Also install a tranny cooler if its not already equipped with one, it is a cheap way to prolong the life of your transmission.

    Good luck with the truck---the dodges are very solid in my opinion.

    Agree with KLC 99 install a tranny cooler. I have a 96 Dodge Ram with 123000 miles I have always towed without the over drive unless I get on the interstate or a good long primary road with not light, but for around town driving I take it out of overdrive. Hope this helps!!!!
