I got the flash to get rid of my CEL issue, and that is gone.

The 2-3 shifting still bothers me....mostly when just "putting" around 20 mph going down side streets....

Yeah, I definitely agree here. I haven't tried to floor it since the flash, as I had gotten so used to easing into the throttle. But, mine is definitely better than before. I didn't have a 4 second delay, but probably 1-1.5 Mississippi's then WHAM! - it would kick in. Now it seems much more responsive and even throughout. But again, easing into the thottle seems to provide the best results.

Have tried easing into the throttle and has made no difference. Truck just doesn't want to go some of the time or knocks so hard into different gears that it sits you back in the seat.

When did this flash come out?

My truck was built in April.

A term used in the computer world to say that you are introducing new code to the computer's brain. Our trucks are heavily controlled by computers. The "flash" is an update of the firmware (brains) that run it.

Usually done when the manufacturer determines that changing it will make the product perform better or correct ones that aren't working correctly.

Just had my truck re-flashed yesterday and the trans is shifting better. My dealer said mine was the first one they had done and wants me to keep him informed on how it does.

I'm picking up a used (well pretty much new, 700 miles) F250 PSD on Saturday. I am unsure of the build date, and don't know if it has the current flash. Is there any way to tell? Or should I just take it into Ford and ask them? Thanks and can't wait to pick it up!!
