727 trans help!!!!!

Dart273, that is what its doing. It is staying in the gear that the shifter is in. so is this normal? Is there anything wrong with it, or do I just have to shift through the gears all the time? I can drive it, when I drop it down into what I would call 1st, its the low gear, 2nd is 2nd drive is drive. So I cant start out in drive I just have to shift. Alot different from my 904.
