My truck recently started slamming between 1st and 2nd and when it tries to go to 3rd it will run up to 3 grand without shifting. I have to let off the throttle briefly and slip it into 3rd, but once I'm up to speed it's smooth sailing. I recently had the driver's side battery completely disconnected and removed to change out the washer fluid tank since it had a hole in it (long story don't ask), and after doing some research I've discovered that the Allison needs to re-learn after it has been unhooked from power. Where I'm confused is I did not unhook the passenger battery so it wasn't totally without power. I tried disconnecting both batteries for about an hour earlier to reset the cel and it worked for a bit. I had my dsp5 in stock during the reset and left it there briefly after i started my test drive. As soon as I turned it back up to 50hp it started slamming again and after a shutdown and restart my CEL came back on. 
Now the truck is fully disconnected again. Side note- I discovered some corrosion on the pass battery hot terminal, it was kind of loose to begin with, when I unhooked it. I guess the point I'm trying to make is, can anyone confirm that what I'm experiencing is the trans relearning, and that I should leave it stock until that process is complete?
Thanks
