Slow automatic tranny shifting when cold
Anyone experience a slow shift first thing in the morning? The RPM's will come up to about 3,000 and it seems like it just isn't ready to shift yet. We are in Southern California, so it's not that cold in the morning. The report from my driver is that the 2006 F-450 6.0L 117K miles is slow to shift from 1-2, 2-3 if the truck hasn't warmed up for about 10-15 minutes. Apparently it's been happening for "awhile" and he's just now elected to say something about it.....Any ideas would help. -thanks

It was serviced by our local Ford Fleet Center, I'm assuming they put the right fluid in it.......hmmm assuming!!! Moving on, it's been happening prior to the last tranny service although, my driver just decided to tell me about it. I'm thinking it might have something to do with an O-Ring or Valve body internally.

I agree but you have to start with the basics first.

Mine had some of the same symptoms and it turned out to be the FICM, had the most recent flash done at the same time, reflash might cure the problem.

We actually figured out the problem we had with the slow shift when cold in the morning. It turned out to be clogged injectors. We had all of them replaced last Feb. and just replaced another one this week......so frustrating.

Had to take it to the dealer to get the codes read. I have a edge insight and another code reader. Both did not show any codes. There also was no check engine light on.
