Ok this is my newest problem. The truck shifts fine going with shifting up but down it feels like it's shifting too hard. Kinda like it has a shift kit in it. Do u guys think the tranny needs flushed and filled or could it be low on fluid? I don't see a dipstick for it. It may be like my stick car is and u just have a drain plug and a fill plug but haven't really researched it yet. Lmk what u guys think. Thanks
