overdrive off around town? when?
I have a 2001 F250 SC 4x4 w/ the v10 AT w/ overdrive
when do you trun the overdrive off? when should I leave it on?
I drive ten miles to work on the hwy at 65 miles per hour, and then 5 miles through town at stop and go traffic.
should the overdrive be off during town/city driving?

Just leave it be. The only time you'd really need to turn off the overdrive is if your transmission is constantly hunting between 4th gear (overdrive gear) and 3rd gear. This mainly occurs while towing in areas with hills to climb.

I leave mine off around town because usually you drive around 40 mph and the trans is shifting back and forth at that speed.A trans mech told me to leave it off around town.If you are driving at 40 or below it makes no difference.

I leave it on all the time unless, like others said the trans is hunting. That only happens when towing. The computer learns your driving habits and adjusts it's shift to your driving style over time. If you turn the OD on and off, it may never get it right.

The owners manual will make suggestions about the intended uses of the overdrive button, however, an un-documented (but effective) use is to button out of overdrive just as you turn into a high speed turn. This will cause the truck to surge forward, settling the suspension, adding weight and grip to the front wheels, allowing a more aggressive entry into the turn. Of course, the lower gear and more direct application of torque helps tpo!

Or, when a victim pulls up next to you at around 60 mph, ease it out of od, they hear the 6.8's revs increase slightly, then at that point they are screwed.Nail it and my rpms reach about 4800 instantly,rev to 5200 and shifts back into 3rd-bye bye.

THRODS my vote , given your commute trip, is to just leave it on.
Because you are asking now, and the truck is 4 years old, I assume you just picked it up used recently.
If that is true, there may be some small benefit to removing the battery cable over night Sunday. Monday when you hook it back up the adaptive learning process will begin to check your driving habits out over the first three or four "driving cycles".

I just bought it
We just sold our 2000 excurson w/ 100K
she down sized
and I bought a new Ford
she had the v10 in the excursion,
when we bought it they told her not to touch the overdrive
I guess I never thought about it again!

You unhook the battery cable to 'erase' the adaptive computer memory. The previous owner could have been *****footing it around town, and the transmission would shift as such, or he could have had a foot made of lead.
It basically clears the computer so it can learn for your driving style.

My truck has always seemed to over downshift, (for lack of a better description). Comes out of OD, rpm's jump way up for several seconds, then shifts again into an intermediate spot that takes it up the hill. If I punch off the OD before it does that, it just goes smoothly down into that intermediate spot and will climb anything without loosing a bit of speed.
