Got mine done today and the service rep wanted to know tsb# and what symptoms I was having. Mind you my truck already got the trans bolts replaced. So while they had it on the lift I had them check for any more leakage. Also told them that I was experiencing the shutter under load had a sled in bed and 2 in a trailer.
After it was done the service guy says he didn't see the tsb for my truck. Ended up he mixed up the vin #. Once he ran the correct one he stated he did run the flash into my truck. But the tsb only calls to run it if getting a check engine light, which I never got. The service manager didn't want to cover it bc ford won't pay for warranty work w/o the engine light. But the clerk said I was all set and I went on my way. I did notice that shifting has changed, accel is a lot smoother. Hoping for the best! So far I can't tell a change in mpg bc I haven't driven malt miles. Will post update. |

Well my update was done today and if the drive home is any indication it definitely is an improvement. Acceleration was a lot smoother and and I got on the main road and set the cruise at 45 mph. The attached pic below is a shot of my instant mpg that was still on it's way up when I took the pic but had to brake for a stoplight shortly before pic was taken. I've done this before and never got above 22 mpg for an instant measurement while the cruise was set at this speed. I can't wait to do some more driving and get some long term data but so far so good!
Take a pic of your trip guage after about 50-100 miles or so. |
Had mine done today. At first the service guy said I already had the TSB. When I told them that wasn't possible, he went and talked to the service manager and came back and said they would run the diagnostics on it so I sat in their waiting room. They came back about 50 minutes later and said they applied the TSB. I feel it shifts better and I didn't feel the shudder but I didn't hit many hills on the way home. I'll have to drive it more to get a better feel for it and see if mpg is improving at all.

Not sure if that instant gauge is the most accurate for determining real fuel mileage, you could have just reset it, and your tranny temp isn't even warm?

To get a realistic comparison you would have to find a stretch of road where you can set the cruise to 45 and then reset the instant mpg page page by holding down the OK button. Try this and see how this compares to how mine did today. I was able to cruise at 45 for 3-4 miles before I hit a stoplight. Good luck, if you haven't had he update I would get it.
I may get the update as well. Thanks again! :thumbup: |

At the dealership now, getting the TSB update performed! Here is to hoping for the shudder, surge, etc. to be gone! Fingers crossed...
|
Is it just me, or did the mileage improvement go away the next day? I got 20 in the city the day of the update. Now I'm back down to 15. :(
