Hard shift, flashing od light
Hello everyone, first post here. I have a 97 ford f250 with the 7.3l engine. The od light started flashing, and it started shifting really weird, going up to almost 3k rpm before shifting, wont shift into high gears. I looked online, and everyone said to replace the vss, i did that, the light still flashed and it still shifted hard, so i unplugged the battery and it worked, the light stopped flashing, but it only lasted a few days then the problem reoccurs. so i did the battery thing again, and it worked for about 40 mins, then it started flashing and shifting bad again. My question is, could it be my battery connection? my positive connection wiggles sometimes, if the voltage dropped too much could it effect the brain to throw something out? I'm kind of lost at this point, any help would be so much appreciated.

Highly unlikely but nothing is impossible.
Pull the codes and go from there. All unhooking the batteries is doing is making the computer forget it has a problem. Truck will run fine until whatever is acting up acts up again setting off a code that puts the trans into limp mode.
If the truck has over 100k miles on it and that's the original trans I hate to say it but a rebuild could be needed.
