We changed the trans filter but only had enough for the filter and 5 quarts of mercon 5, would that make a diff? Also we seem to have reverse but nothing else. We also have a ticking noise on the passenger side behind the tire? And the oil is not reading on the dipstick like it is completely empty, what would be wrong? Also makes the reeeeering noise when driving. If there was no oil in it would it effect the transmission gears, and if there isn't enough transmission fluid in it would it effect the gears?
