I read that if you have O/D off that the truck shifts at higher RPM's.....dunno if its true or not. But yea I do it too.

I turn mine off when I am in a racing situation. It seems to change the shift point/engine RPM. The truck seems to stay in each gear longer even at part throttle, at least that is what it feels like.

Be careful doin that
No over drive is probly fine for around town and the occasional romp on the highway. However, making a general habit of locking out your top gear, where life is easiest for your engine in high speed situations, can cause premature engine wear. My parents wore down the engine in their van and killed the transmission at a little over 90K by driving with over-drive locked out pretty much from day one. Seems they werent too familiar with the principals of automatic transmissions having owned manuals all their lives, and they dont generally make a habit of reading the owner's manual, which specifically stated that the manufacturer recommended leaving over drive engaged in most situations.
I know that's not necessarily a concern for many on here who tend to change trucks every couple years when something new comes out, but it's something to consider if you're the type that likes to hold onto a vehicle forever plus a day.

Well a Ford transmission tech at our dealer said the cause of some of my parts failling in the tranny was a result of playing around with O/D on. Such as burn outs, doughnuts and the ocassional race on the highway. From my understanding the tranny has two input shafts and a sprag that links them. With the O/D turned off the input shafts are locked together and make the tranny stronger. But if the O/D is left on the tranny has lost some of it's torque handling capacity. I ended up lossing my O/D when the part broke. Caussed some of the parts to get welded together that should of been three different pieces and the sprag was toast
Now when I get in my truck I just turn the O/D off unless I am on the highway. Plus when I have to get on it the tranny seams to react faster and not have to shift down 2 or 3 gears.

OD off???
I disable overdrive if I'm in stop and go traffic and cruising through lower speed limits. If I can't maintain 50 mph or above for any reasonable distance, I'll lock it out. Allowing the tranny to continously hunt between second, third and OD will cause premature wear and tear on the trans. and lugging in OD will cause undo high trans. temps.

I use my Overdrive button as a transmission brake or as some would refer to as a jake brake. I have owned between my company and I over 36 Ford trucks in my life time and have never has a transmission issue yet except service and one F-350 had a leak.
. As soon as I want to slow down from 70 to exit on a ramp I will just pop the button in and the tach goes from 2800 ish to 3600 ish and the truck slows down and it helps save the brakes too.

I always "USE TO" shut mine off under 60 MPH, but ever since I left it off by accident during a 135 MPH plus blast one afternoon I "NOW" leave it on. I hate seeing a tach under 2000 RPM driving around town, but seeing it scream to 5700 RPM in third kinda made me change my way of thinking. 
Another RPM or so and it would have hit the Limiter anyway, I have it set for 5800 RPM

The only time I use the OD is when I am on the highway. Otherwise it's off. I always leave it off when running the 1/4 mile.
