Okay guys so I posted on here before about a 2-3 shift issue we’ll I ended up bringing it to a shop and they found some broken wires and changed my ebp tube and sensor and so far it has fixed me shifting! But every few times my O/D light blinks and it throws a vss code causing my truck to start jump shifting.. why?? I’ve put a brand new pigtail and motorcraft vss in it.. why does this keep happening..?

Just a wild guess since there are a lot of possibilities, but it could be due to an intermittent short or break somewhere else in the wiring. Generally you see that kind of thing with stuff in the engine compartment, but it's possible anywhere really.

It would be easier to help you with some information about the truck in question. If you already had a thread about it, you should have continued in that one so we could review it all. But you should put it in your signature.
