Takes about 5 or 6 miles. Is this normal? Temps right now are low 40's at night. Thanks!
Also gentlemen you will notice in the original post that his temps are in the low 40's and it does this for 5-6 miles.
As BTH and CandaGuy both said in the first couple of posts, this is not correct, it can be injectors or transmission problem.
There are TSB's out on this:
06-2-13
http://www.ford-trucks.com/tsb/fullt...hp?tsb=06-2-13
And as BTH stated if it is within the 3/36 warranty no charge.
So give the techs a break and let them answer fireman_19's question and solve his problem (and possibly yours). If you are past your 3/36 warranty and into the 100K warranty, and you are happy with how your truck runs then don't take it into your dealer. Choice is yours to make.
Hope this helps

So if I understand, and I may not, at 40F this could be an problem, but at 22F, it probably is not. I always understood that cold affects any engine, gas or diesel, but it appears in the case of waterboy_fishing there should be no affect on the tranny at those temps. Am I OK so far?

chili7,
If you click on the link to the TSB in my post above, you will see that the testing is done with the engine ECT between 20F - 50F, so yes you could have an injector issue at 22F.
Yes cold effects both gas and diesel engines, But comparing the 6.0 PSD to your old gasser is not an effective comparison, since the engines and transmissions of these vehicles are designed different and of different age.
So do you have a problem with your 6.0 PSD when it is 22F outside, maybe. Read the TSB and see what you think is the best course of action for you to take with your truck.
Hope this helps

Well, I just got off the phone talking to my local service rep and he said this is not normal and I should have the truck looked at. Apparently Ford has come out with a better injector if that turns out to be the problem. This has been a great, and at times temperamental, discussion but I'm glad you guys are hear or I would have never known about it.

Hard shifting when cold...i vote NORMAL as well.
If the temps get to even 55 degs and the truck has been sitting for 8 hours or so, mine shifts hard for a few miles. I wouldn't worry about it. You start taking it to ford "techs" and they will find all kinds of 'Problems'.
Easy does it, drive it and leave it be.

If you are happy with how your truck runs, you don't have to take it your favorite Ford tech, just beware that this is Not Normal operation at 55F temperatures.
Also there are alot of Good Certified Ford diesel techs out there. If you don't have a good one at your local dealer, then i would find a new service department with a qualified and knowledgeable diesel
tech.Hope this helps

I appreciate all this duscussion about this issue. I had no idea this would get such a response. I decided to let it warm up an extra couple of minutes and the "problem" seems to ease. I have 77,000 miles so taking it to the local dealer is not an option. No check engine light and it runs smooth when warm so I'll keep going. thanks!

You are aware that the engine is warrantied for 100k miles and any warranty repairs on the engine would only cost you the $100 deductible.
