LS Transmission

My teenage grandson "helped" me change the oil by accidentally draining the transmission fluid from my 2001 LS automatic transmission. I can't find out how to replace the fluid. The manual says there is no dipstick to check and doesn't tell how to add fluid. Since he drained about 3 to 4 quarts, I am hesitant to drive the car to a dealership, for fear of damaging the transmission. It's a sunday evening here so there's nobody available to ask.
Can anyone tell me how to add transmission fluid.

You can't, have the thing towed to the lincoln dealer they are the only folks tooled to handle the job. Let them know what happened and just ask them to do a tranny flush.
