So I just finished rebuilding my transmission for my 95 4x4 Blazer. I installed it & put in the required fluid. But now I have no OD or D, and when I drop it to 1st, it slips a bit, up to 2nd, slips a bit also. But if I get up to speed in 2nd, I put it in D, and 3rd engauges. However, it doesn't downshift to 2nd when I step on the gas. And OD still doesn't work when moving. Any ideas? I'm confused. Thanks!
