Hard shift

I have 1200 miles on my 2012 and twice now the truck has shifted from 1st to 2nd so hard I thought the guy behind me hit me.

Has anyone had this issue or know if there is a fix?

Another issue is the transmission seems to rev in N between 1st and 2nd almost all the time I ease away from a stop. Almost like it doesn't know what gear to go in to.

i thought the was a TSB for that requiring a computer upgraded program , but i would have thought that your 2012 would have already had it.

Short answer No.

It has only happened the two times. I am just over 2000 miles now, but will have it looked at when i have my first oil change. Unless it starts to happen again or more often. For now just waiting.

Just test drove (11/21/11) a brand new 2011 250 Lariat 4x4 CC w/6.7 and 6-speed. Got about 8 miles into the drive and it too decided to go into N between 1 and 2 for about a second after turning a tight slow corner. It also felt like I had been hit from the rear. It was a definite hard metal bang.

For the record, it was 75 degrees, sunny, and dry pavement. The vehicle had a total of 000032 miles at the start of the test drive, 000040 at the end.

I walked away from the dealer shaking my head. Going to test drive something else tomorrow.

Before you go away thinking something is wrong you need to know about the trans. Your salesman should have told you about it. The trans "learns" how you drive. It take about 3000 miles for it to adjust to your driving habits. A truck with 32 miles on it obviously hasn't had time to do this. My truck does this everytime I retune the trans with a different tune. When I drove mine off the lot it did this for a while. Before I tuned it at 25,000 miles it was the best, most intelligent shifting transmission I've ever owned. I've got about 1,000 miles on my current trans tune and it does it occasionally but it's figuring it out. Ford call it "Adaptive Transmission Strategy". Go drive somebody's truck with more than 5,000 miles on it and you'll see.

Ditto the above. I had a couple rough shifts in the first couple months. Then never saw another untill last week. Temps here had dropped and I had left the truck outside with an all night cold soak. Had a couple rough shifts first thing in the cold morning, but once warmed up, no more problems.

Since I'm at 34,000 miles and the bumper to bumper warranty is just about up, I took it in and asked dealer about it and a steering oscilattion I also just noticed. They dropped my pan and ordered some new servo's.

I really wonder if I should have kept my mounth shut, as they tranny has really worked pretty well once it learned how I drive. But I tow hard and have more miles towing than non-towing, So it was time for tanny flush any way.

I don't think it is a transmission learning your driving because I have 42000 miles on mine and it is doing the same thing between 1-2. It does it warm and cold.

Stock for now.

Just had my trans rebuilt at 11000 km. The front oil pump in trans has been upgraded. Apparently first generation would lose prime and cause shifting issues. Still get sloppy shifts though. Not really happy with trans!!!
