5R11OW Overdrive not functioning
For some time now my 2007 E450 powerstroke auto transmission will not shift up to high/road gear.
When it feels like it,it will shift to overdrive almost flawlessly and lock up and not slip at all.It is more likely to work when starting off cold,and least likely after a 20 to 30 mile drive,on my return trip.
I took it to the dealer and they say my overdrive is "shredded".
They will do an overhaul for 5000.00,depending on what parts need to be replaced,or install a complete Ford remanufactured for 6800.00.
The day before I took it in after I had made my 40 mile round trip,it started going into overdrive easily,and I could use the tow button very easily up and down repeatedly without hesitation.Also automatically went in to OD on it's own.
I have changed fluid,filter,and the cooler trash filter,all with Motorcraft parts and fluid.When it wants to it performs flawlessly,shifting through the gears and into overdrive like a sports sedan.
It seems like the refusal to hit overdrive is getting more frequent,even when cold.
How can it be shredded??

Well I question their diagnosis, I also question the prices. I would not do a shop rebuild of a 5R110W unless they specialize and I know they don't. The 6800.00 quote is 3k high even for a dealership.

The tranny for any competent mechanic in a shop shouldn't take more than 6-7 hours MAX to remove/install the tranny. A new tranny/reman should be 2800-4000 and labour max $1000 @ 7hrs @ 140/hr kinda thing
I've had them in and out in 4-5 hours replacing a flexplate
If it's shredded it's impossible for it to start working again.
You have an electrical issue not a physical failure IMO but there are others who know far more.

Sorry
Sorry Mark.It was my intention to find out recline and crusing rpms in the other post.I thought I was going to have to use it around town,and not hiway.Repair was not affordable.
I called Performance Diesel here,and they recommended Kimmer Transmission and Gear.
I took it in and they found the temperature switch on the valve body was saying it was -82 and the truck was trying to keep itself warm by no overdrive.They replaced the sender and my problem was solved.
I just did a 1/2 load trip from Denver to Aspen over the hump and passed everything on the road.Flawless performance,most of the time in overdrive.Cost for repair was 304.00.

A code would have been thrown for a bad fluid temperature sensor (and you would also see it with a scan tool). IMO you need to consider getting ForScan (on a smartphone or a laptop).

for future searchers stumbling on this thread - it is a great example, as Bizmic advises, for spending $40 for a good OBDII set up to constantly monitor your trucks, and a great example of the danger in going to dealerships. Geezus, that service writer was trying to rip him bad. It's almost criminal. There's no excuse for a dealership tech not properly diagnosing a bad sensor. I expect that if he had chosen to let them "rebuild" his, after explaining to him that the rebuilds have a shorter warranty, they would have just swapped in a new sensor and taken his money knowing these 5110ws will be fine. If he went for the new unit, that'd be OK too.
Even if you don't do the actual work, knowing what the problem is, by having the tool and doing your research, will protect you from dishonest techs and commission-based service writers. I have a truck sitting in the driveway because I don't know what's wrong with it and won't take it to a tech until I do. I'd rather Frenchkiss an angry pitbull.
