1991 Chevy Caprice 91 Caprice Shift Problems

Have a 91 chevy caprice sw, that would rarely move in drive or reverse. I dropped the pan and changed

the filter and fluid. I found a few tiny tiny pins in the fluid that seemed to be the same size. Now

the car starts, reverses, drives in overdrive to 2nd gear, then while getting gas it cuts out at almost

exactly 25MPH, and then while still getting gas, has no power from the transmission. At about 33MPH I can switch back to OD from 2nd and it drives but does not seem to be in OD at all. In D I get nothing. I can drive in 2nd OK.

I would say the size of the pins are about 1/8 of an inch, silver in color and appeared to be undamaged or marred.
