I'm guessing from the question that your car has an automatic transmission. You will find two bolts coming out of the rear portion of the bellhousing. The upper on is to measure/fill the fluid, while the lower one is to drain the fluid. A car of that age would probably be better off draining all of the transmission fluid and filling it until it pours out of the filler hole. That's all it takes.
