I can't remember the speed, but remember in reading in the manual on the 12 model that after it looses a certain amount of speed if one lets it try to claw its way up an incline with the cruise, that the cruise will automatically disengage.

 

Sorry guys. Just realized I commented on the wrong thread. My bad.

 

Mine will actually slam into into 3rd from 2nd at about 5000 rpm. It has done it twice. That after it loves to hang in 2nd ALL the time until at least 5000 rpm. Dealer has not been able to reproduce, so they hooked me up on a flight recorder. Sure hope this weekend I can get it to act up for the recorder.

 

did you ever get this shifting issue fixed?
-mine is doing it and im going nuts trying to get someone to fix it

 

I also experience the 2nd to 3rd shift slip (feels like the transmission is in neutral or disengaged) prior to engagement. It happens usually once or rarely maybe twice toward the first couple times after the truck is first started and taken on the road. After it happens once it will usually not happen again and sometimes it will not happen at all. Most of the time the slip is relatively minor - I think exactly how this is experienced has to do with how hard your pushing it when it happens, if you are gunning it when it slips, it will fly up into high RPMs and slam into 3rd which feels like crap for sure.

 

Spoke with the Ford rep today- she advised me that my service manager now state they never have duplicated the issue although i have all the service tech's records stating they have felt it, in my case they have reprogrammed a couple times, replaced shifting sil's and most reciently rebuild my transmission ( but have never duplicated they issue) my truck shift's funky every day and last thursday slammed into lower gear when slowing down for the guy in front of me (talk about a startling thing). I cant believe for a min that any of this is good for the tranny.rear end and u-joints not to mention is alittle distracting from actually driving. holding out hope for a positive arbitration with the lemon law-- guess then i'll look at a toyota if im sucessful which is really not where i want to go but cant see putting all this money in this kinda crap-- wish ford would do the right thing with these things i love the look and stance of this truck

 

Mine still does the same thing, and I even tried a different dealer in hopes of them trying to fix it, they also said they couldn't duplicate it!

Reprogrammed multiple times, and new solenoid valve body, still there...

 

Well got news today that Ford agreed to install new steering column in truck. now if they can address shifting issue might have something.
Pretty sad though a truck with 14000 adult driven miles and it now has a rebuilt transmission that still doesnt work right,new steering tie rods and parts and now a new steering column-wonder what the guy on dirty jobs would say about that on a commercial-ha ha

 

Just got my truck back last night. The converter hub seal was replaced, had been leaking trans fluid for quite some time (small amount, but still a leak). We'll see if this resolves it. 18k miles on the truck.

 

That is the same seal they had to replace in mine last year. Mine was leaking from new. It was only a couple months old when I took it in. It has been good since.

 

Good to know. Mine's been leaking for a while (9-12mo's maybe). Here's what they ended up replacing/doing:

1 - BC3Z-7A248-A - SEAL ASY - OIL
4 - W715234-S437 - NUT
8 - XT-10-QLVC OIL - AUTOMATIC TRANSMISSION

AUTOMATIC TRANSMISSION ASSEMBLY - REMOVE AND INSTALL OR REPLACE
AUTOMATIC TRANSMISSION SEAL - FRONT PUMP TO CONVERTER - REPLACE 7A248

 

I went back and checked my post. It was the rear seal on mine where the transmission joins onto the transfer case. Either way I have had no more problems with it.

 

Story about my new 2011 F250 6.2l Transmission problem and solution...

Friday morning I had to leave quick for work and as I started to the truck and as I gave it gas I noticed immediately that the transmission was slipping , flaring , shifting out of each gear and getting stuck in neutral before it would slam into the next gear... happened in 1st through 5th gears. It was flaring so bad I was not sure the truck would even make it down the road. I tried to make a left turn into traffic and I was actually scared the truck was going to leave me stranded in oncoming traffic.

Truck has 22,500k miles and I did not notice any serious problems to cause warning before, however in retrospect there were several warning signs. I called the dealer and set up an appointment same day, luckily they are only 3 miles away. The truck started to flair and slip less as it did warm up. I noticed that as the transmission temp reached about 130 degrees the slipping and flaring stopped completely , not sure if it had anything to do with the engine temp also raising in temp also.

The dealer could not replicate the problem the first day. My service rep recommended to me that they keep it overnight and try in the morning. Overnight I was able to check out this forum and see that a lot of guys were having problems shifting in to reverse as well as having slipping. I noticed they had some success when reprogramming and changing a few solenoids. I was prepared to talk to my rep about it when he called the next morning. after checkin out the forum I realized that I had been having the harsh delayed shift into reverse multiple times in the last few weeks. I figured I was just trying to shift into reverse too quick after I had start the truck. It was so harsh it was like trying to shift into drive out of park on a really steep hill.


Got a call the next morning and he said they were not able to replicate the problem again... I got frustrated but... he did say that the tech noticed a small flair in 5th gear. He also explained that there was a TSB and that they would replace some solenoids as well as reprogram. The truck was ready for pick up that afternoon. When i picked up the the truck my service rep told me the TSB was for delayed shifting into reverse as well as flaring and difficulty shifting gears. He told me the truck would be learning my habits for the next 200 miles or so.

On the way home I did notice that the truck was shifting smoothly... also differently than in the past. Must be because Its re learning my shifting pattern. So far so good. I will keep everybody posted to let you know if the problem re occurs

 

Thanks for the great post. Lots of good information in there.

BTW Welcome to FTE!!

 

Well you'll find out soon, mine always had trans problems from day one, and i was always waiting for the next reflash because they promised that would fix it, then finally the solenoid TSB and mine seemed to be little better at first after the solenoid replacement, but what i noticed is that they also reprogrammed the computer at this time, they clearly modified the software to make smoother transition form gear to gear, and whatever else they changed in the software to mask the problem, but now my truck has no power after the solenoid tsb visit, this pisses me off, i feel that they are trying to hide the problem instead of repairing it, i noticed the problem still though, especially after the trans completed its relearn process, back to the same old bs. Took it back into dealer, the trans tech verified the shift flares and hard shifts in lower gears, the going into neutral before it changes gear episode, the 5th gear downshift issue, and everything else that the trans is not doing right. Has been at it three times now just this last visit which has taken over a month already, its literaly been opened up about three times, not to mention all the previous times i brought it in for the trans issues, and they are just throwing parts at it, valve springs, valve bodies, clutch packs and whatever else, with the problem still being persistent afterwards, and there is no end in sight. I certainly hope that's not what you are about to go through. The worst thing the transmission does is the jerk when downshifting from third to second or second to first at a stop sign, it literally makes the truck jerk forward, and i can imagine how if you are close to another vehicle or worse yet a pedestrian crossing the street in front of you, what a safety issues this is, and potentially a safety recall for ford, if not potential lawsuits. And by the way this transmission is what was supposed to make these trucks better on fuel economy, well let me tell you from experience that with the trans problems i have its worse on gas.
