I've been working on my 72 dodge motorhome. It has the 413 and the 727. Trying get it back up and running. Rebuilt the carb, redid the brakes, changed the rear gear oil out. Went to move it and nothing. So I pulled the cooler line and it was pumping out a steady stream. So went to test line pressure and I'm getting nothing from it. I have to have it moved out by next Monday so this is not good. Looking for any ideas, hoping it's something I can fix without pulling the trans. Now this did work when I moved it about a year ago but had no brakes then. I checked the fluid level in neutral and it was just above add a pint to I added a touch. When I shift it it doesn't feel like it's engaging at all. Now when I had the driveshaft off the transmission output would spin, but when driveshaft connected won't spin at all .
