The problem that you're having is mostly caused by a worn valve body, specifically faulty solenoids (Shift A or Shift B solenoids), a bad N/D accumulator, or a worn forward clutch assembly (worn clutch packs). These cause what you're seeing, called delayed engagement. You need to rebuild your transmission. Of course make sure you have sufficient transmission fluid first. It's the #1 cause of delayed engagement and other problems. But if fluid/oil level is good, then your transmission is at the end of life, rebuild it or buy a new one.
