I have a 727 that was rebuilt in March 2019. I had the trans rebuilt but I installed it. It's a floor mount shifter. When the car sits overnight or on a slight incline, overnight, I have to run it through Neutral, Drive, Neutral, reverse a couple of times until the trans engages. I did change the dip stick because the old one was broken (the handle). I changed the dip stick only, not the outer tube. I compared the new to the old, they looked the same length and the markings were the same.. When the engine is hot, it shows full. I'm checking it in neutral (per the Trans builder). The trans seems to shift properly. Could the dip stick be off? It has 8 quarts of ATF (the converter was empty). Do I need to add a little more ATF? Thanks
