I have a 2006 dodge durango limited 5.7 hemi. The question is I recently serviced the transmission as in I dropped the pan changed the two filters and reapplied pan. I filled the tranny with valvoline atf 4 while it was running in neutral until it was in between the two hot lines. I, while in park, ran through all the gears and checked again. Everything was fine however yesterday when I returned home from work approximately 40 miles I left the engine running and checked the tranny again. The fluid did not even touch the stick. I left the vehicle sitting all night and again this morning checked. The fluid was in between the top cold and the botton hot lines??? Shouldn't the fluid be lower. Doen't seem right. What is the proper way to check to see if you have enough fluid in. While it is cold sitting all night or when you have been driving it and the engine is warm and still running.
