I have a 2005 f150 (130,000 on the clock) with the 5.4 and 4x4. The tires are stock, I have an edge programmer that I used on setting 2, the tow performance one, with a custom tune that slightly advanced spark and firmed up the shifts. I don't tow and have only don't some light off roading but nothing in the last couple months. I use the edge to monitor the transmission temperature; I've never seen it get over 180 with the norm around 150-160 degrees F. Since it got cold out my truck has had a whine that I thought sounded like it was coming from the engine bay. It progressively got worse until it was always there but would get quieter when the motor warmed up.

Then earlier today I experienced what felt like a loss of power then the motor would rev up. The transmission would shudder and then it would be fine to drive. This happened 5 or 6 times in the 3 mile trip back to my house. I checked the tranny fluid, which was good, and put the edge back to stock and pulled the batter to reset the system.

Tonight I decided to try to drive it to the supermarket down the street to see if the problem persisted and if turning od on/off changed anything. It started fine then when I got about a mile from my house it started slipping again and revving up. It would barely move so I decided to turn around and go back home. I limped it a couple hundred feet before the transmission dash light came on and said transmission failure. I got it towed back to my house then used the edge to pull the codes. I got

p0720 - output speed shaft sensor
p0722 - output speed shaft sensor no signal
p0731 - incorrect first gear ratio
p1000 - OBD system readiness test not complete
p2106 - throttle actuator control system - forced limited power

Is there anything I should check or should I have it towed to the nearest ford dealer? Based on these I'm hoping its just some sensor or something simple. I'll get under it and check all the wires to the transmission tomorrow to see if any got loose or have issues.

The whine is definitely coming from the transmission. I went out today to check the oss but didn't have the correct wrench size to remove it so I started the truck to see if the problem persisted. Upon start-up the motor idled at 1500 rpm and the transmission whine was very loud.

I had trans problems on my 06 5.4 3V with Edge EVO. I had the trans rebuilt, sold the EVO (never again) and am still dealing with trans issues. Intermittent slips, hard shifts, etc.

I talked to a couple shops today and found that I can get the transmission rebuilt for $23-2500 or I can have Ford put in a re-manufactured unit for $3100. All the shops had a warranty of around 12 months and 12k miles while the Ford unit has their 3 year unlimited warranty. There aren't any Jasper transmission installers anywhere near me, otherwise I would go that route. I would love a BTS or equivalent but the cost puts that out of the picture. I won't tow often but I do plan to get 285/70/18 KM2's so it will have more tire weight than stock. Which is the best option? Are there alternatives I haven't thought of?
