So I just bought a 2005 maxima and it been having some hard shifting took it to get new trans oil and still had problems so I got the Lucas, stop hard, shifting oil thing and it definitely helped but still feel hard.than I took it to my mechanic and we test drove it and he said you’re supposed to feel the shifting he doesn’t feel anything funny I’ve never drove in something with this big of an engine in before, has anybody have a problem like mine?

Or any options thanks
