automatic is shifting strange
I have an 08 F250 SD 6.4 diesel. It is shifting in a mannor I am not used to. When I accellerate up hill ith no load, the truck seems to hunt for gears. I must kick the accelerator to lower the gear for acceleration. I am in my first diesel and drive on mountain roads but this occurs on small hills in town. I ould expect better acceleration up hill. Is this something that ill go aay ith time or do I need a reflash?
I expect to to soon. I have 3200 miles and have experienced a few regens but none would keep me from accelerating up a small hill ithout feeling I need to stomp the pedal to donshift.
One other question, I have been searching for the valve to drain ater from the fuel, but cannot find the lever. Can you direct me?
I am very new to this and appreciate your help.

I think it takes a bit for the transmission to "learn" how you drive. It could have learned how you drive incorrectly, and that is why you don't get the greatest of shifting. Try disconnecting both batteries for a bit to reset the transmission computer, and see if it shifts differently

There is a new flash program for rough shifting and hunting of the gears just take you truck to the dealership and let them know what its doing it makes a big difference.
As far as the drain valve go under the drivers side of the truck on the inside of the frame, around the drivers door area, you will see a yellow lever on the filter.

I think what he means is that the 6.4 computer, has flash memory on it, much like a memory card for a camera or a USB memory stick, that records everything that is done to the truck. Including any fueling or max boost changes or the like, that tuners are likely to do. It also holds such information like your driving style for shifting the transmission. Older trucks recorded this information in memory chips that would get erased when the battery was disconnect, the new ones retain the meory, even after the battery is off. Atleast that is how I understand it

"Overcoming" simply means properly implementing a flash erase procedure that will not only remove the aftermarket flash, but also the associated flash logging in the PCM showing that any changes ever took place.
This is not something that can be done by an end user, but it is a technique we will be implementing into our own tuners when they do become available.
So, yes, it is possible to run aftermarket programming without leaving evidence for Ford to see. Ignorant nay-sayers flame away
LeadHead's last post is a very accurate description of how both the self adaptive and flash-logging memory works. Relevance of all this to the original subject is that it is no longer possible for the end user to clear the transmission's memory without dealer equipment.

I have been waiting around on SCT for months now and have completely lost my patience. I am and will continue pursuing other paths.
As for a timeline, I honestly cannot quote one. The two top priorities here are 6.0 Fuel Injection Control Module Calibration and getting our 6.4 products put together; so it is near the top of the list.
