towing everyday in the summer question

[racemx713@yahoo.com]

I live/work on a peach farm in the summer and I will be towing peach trailers with my 02 f250 7.3 everyday, and multiple trailers per day. These trailers can weigh between 5,000-7,000lbs fully loaded. Most of the trips are short 5-10 miles. My question is, should I turn my overdrive off when towing the trailers to prevent the tranny from getting hurt? My truck is stock by the way, any info would be appreciated thanks

if it keeps shifting in and out of o/d yes. i tow my 2 horse trailer in od no probs. btw. get a better tranny cooler and you'll be fine.

Yes, keep it off esp if you are driving through a town... what you dont want is it shifting in and out of od... once you get going at 40ish the tc locks, then it will fall into od. And if you are planning to drive under 50ish keep the od off

when i had auto trucks i would always turn O/D off. i have talked to some tranny guys and they said the number one cause of a blown tranny behind a stroke was because it was left in o/d tryin to pull a hill with alot of weight

get a bigger trans cooler for sure! you only need to lock out OD if its hunting in and out of OD. I pull my 12k 5er in od and it only jumps in and out if I can not stay above 1700 rpm or so. if I can keep it at 2k rpm Ill push right along at 67 mph and its almost like nothing is there

thanks for the info guys, I will be going under 40mph the whole time so I will keep the O/D off. We had a 04 f150 on the farm and in 2 summers the tranny was shot, most likely because it was in O/D the whole time while hauling the trailers.
