ok i was out messing around today and i pulled my trans into 1st and i shifted it at 4000 and it wouldnt hit til 5500 and after that it would shift when i shifted, but when i pull it down and just go slow like anything under 3500 it will shift now but if i get on it, it will hold its self in gear longer. does anybody know what is going wrong or is this just what they do?
