I have a 1993 Oldsmobile Cutlass Sierra that developed a hole in the
transmission oil pan after I hit a rock on a gravel road.

I noticed the oil dripping under the car, so I quickly drove it to the
farm and parked it, with the intent to work on it ASAP. The car
actually ended up sitting for a couple of months, and when I started it
to work on it, it would not move in forward or reverse.

I added several quarts of oil to the transmission, but it still doesn't
not move.  When I parked it, it was fine.  The car was running great,
with no problems other than the leaky transmission.

Is there something I need to do to get the transmission to work again
(i.e. somehow fill the torque converter with oil)?

Any help would be appreciated.

Thanks,
