my owners manual say tow haul eliminates 5th "od" and od off eliminates 4th and 5th. its best for around town so your not always shifting as long as you dont get above like 55 its ok to use

KABOOOM!


I don't have O/D off on mine just tow/haul, and it doesn't say squat about it in the owner's manual. However I do use it anytime I tow to get the more aggressive downshifting especially with the jake brake.

Default Tow/Haul Switch

Actually I believe it merely LOCKS the torque converter and cvhanges your shift points. At least that's what it does on my 2008 2500 CTD. JMHO I shift it down (auto) to 4th when below 45 mph. Brake is always on to keep turbo clean. No regenerations in 28K, but have had five reflashes and three "Check Engine" lights.

Your 2004 ram most likely does not have an od on off function, that's on the newer trucks. Tow haul does not lock the torque converter, it unlocks it to increase torque multiplication which is why when you hit the button your rpms rise. The transmission still uses all of it's gears, it just holds lower gears longer, especially when going uphill, as well as downshifting when you hit the brakes or let off the throttle. I don't know if you have an engine brake, so the latter won't help much if you don't but if you do it's a neat feature. I even use my tow/haul button when driving on steep mountain roads and in the winter and these functions help in those situations as well. The 55 mph thing is false. I have towed over 35000 miles at highway speed with the button pushed, and have run as fast as 87 mph when I wasn't paying attention while making a run for a hill. My truck has over 90000 on it now and hasn't given me a lick of trouble. I wouldn't recommend going that fast towing though, it was just one of those oh sh*t moments we all have from time to time.
