2004 dodge 2500 48re. I pulled my valve body out to see if previous owner had upgraded any internals. I found a billit TC and GM govenor solenoid. I put everything back together and now it shifts ok untill 3rd. It just slips and when you let of the accelerator it feels like you are putting on the brakes untill it gets under 10mph and then I think it is shifing back to second and the "brake feeling" goes away. I have no CEL, but I have P0868 and P0713

uh oh, I had the accumulator upsidedown. Do you think I damaged anything?

I put it back in the right way this time and everything seems ok.

 

Its fine, seriously doubt you could have damaged anything especially if it is operating normally now.

 

I think you found it quick enough that you shouldn't have caused anything to get wrecked.
