    Slipping is usually a sign of low ATF fluid. How does the transmission fluid look? I assume you checked this first. It should be cherry red in color and at the right level with the engine warm, running and in park. If not, then change the transmission fluid and filter first, before you make any expensive repairs. As for additives, I have used Seafoam Trans Tune with some success in older transmissions. You simply put it in the tranny for a few days and then flush the ATF fluid and replace the filter. The Seafoam will clean out the varnish or gunk that may be causing the valve or clutch pack to stick. Try replacing the old ATF with a synthetic ATF fluid like Mobil1 or Redline as they are a bit slippery than the regular ATF Fluid and will further help clean deposits out. If this does not resolve the issue, then you may be required to do a partial or full rebuild of the transmission. Good luck!
