I would like to know how to change my shift points. My problem is this, every thing is fine until we get to 3rd and actually 3rd is ok its THE LACK OF LOCKUP between 3 and OD. Lock up and OD seem to happen at the same time. Some times ( if pulling a hill ) I will get lockup in 3rd and then OD. IF AND WHEN it will do that, it is a much better driving experience.
But when thet happen at the same time you have nothing left as far as power goes. My factory Cal was NVK3 Ford changed it to XC3F, they said it would be better..BS!!! If you read my Sig you will see that I have had the truck since new and yes it took this long to get fed up with it..
How can I fix this issue??

Thanks Troy

i also had the same issue towing. i got my chip retuned by swamps and got their travisf350 program. this will fix this issue. mine shifts into 3rd at 35mph then lockup and od at 45mph. makes towing very pleasuable not to mention all the extra power. im sure any of the custom tuners could fix this for you
