With my truck turned off the dipstick reads over full. I start it and run it and then check the fluid level while running and it reads empty on the dipstick. I keep pouring in fluid and I can here a sound in the dipstick hole that sounds like a quiet garbage disposal sucking down the fluid. But will not read on the dipstick while running. Apparently I put to much fluid in it now. Because It started burning smoke out the exhaust as I put the last quart of transmission fluid in. Now with the truck off it reads way up towards the top of the stick. But when running it reads empty still. I need help quickly.
