Default think there's a problem?

there was a small dead spot in my truck. sometimes it would bog out between 40-50 mph....

The good news: the dead spot is gone! i can accelerate straight thru it, no prob!

The Bad News: The truck won't shift into OD at all, takes off from dead stops in 3rd, won't shift into 2nd or 1st on its own, and no 1st gear at all i think


sheez

so here we go:
1) no OD at all
2) takes off in 3rd
3) will not shift into 1st or 2nd on it's own
4) no 1st gear
5) i can manually shift it to 2nd no prob.
6) i can manually shift it to 1st, but feels like second.
7) when taking off in 2nd, i can shift to 3rd, but nothing happens.
8) when taking off in 2nd, i shift to drive, it shifts to 3rd.
9) no change when shifting from 1st to 2nd namually.
10) makes no wierd noises or anything


so you think there's a problem?
