I have a new 2011 F150 4x4 6.2 liter with about 1200 miles. I haven't liked the shift quality since buying a little over a month ago. I think the upshift from first to second is kind of rough and it feels like it's slipping a little from second to third gear. I've read a lot of negative posts/reviews on the 6R80 transmission, and some people have said it got better over time, or it got better with more aggressive driving. I do notice it shifts better if I drive it a little harder. The build date according to the sticker is 4/11 and I don't think there are any TSB's for PCM updates for this year/engine/model. I'm wondering if I should bring the truck in now for the dealer to take a look or drive it for awhile longer to see if it gets better? Any advice is appreciated.

Thank you.

Thanks Shotgunz, there is no specific tsb for the 6.2 liter, but I heard just doing a general reflash sometimes helps. I'd just hate for them to make it worse.

 

get it in and get it on record. you never know if you have to lemon law it you will be glad you got a records of it! i have had mine re flashed a bunch of times and the trans merconik(spelling) valve body changed out. they just came out with a new TSB in tin Feb thats should help me. ill have to see after i get 500 miles on and see if it worked. but back to your problem don't let it go, you have 18 months and 3 or 4 times to fix it and if you don't get it fixed ford might have to buy it back and get you a new one. i know it sucks to buy a 40,000 dollar truck and have it act like that! well good luck with it.

 

I did go the dealer about a week ago and they didn't find any trouble codes or TSB's to re-flash the PCM. The shop foreman drove the truck and said that is seemed okay to him, in that, it drove like the 6 speed transmission should. He said the shift set-up and lack of throttle response is designed for fuel economy rather than performance. He actually mentioned "off the record" getting a tuner, which he felt would help significantly. He did, however, say that the warranty would be voided for any damages directly caused by the tuner, although he doubted there would be any problems.

 

I got an X3 from Mike at 5Star and mine shifts like a dream. It has a little more giddy-up now also

 

i have been toying with that idea but just cant grow a pair and do it lol
sow how dose it work is more of a tork converter setting or trans setting? dose it help MPG as well? sorry for my

 

Not exactly sure, I don't get into the nuts and bolts of tuning I just know it works. I mostly got it for the shifting improvement and a little extra oomph due to the bigger tires, it liked to hunt gears on hills but now it holds them and doesn't constantly shift. I don't hammer on it and only tow occasionally just needed a little extra to get it back to where it was before the bigger tires. Maybe someone else can clarify for you? Mike has a good rep around here and other forums so I went with their recommendations when I was ready.
