What is the towing capacity of a Mazda 626?

Can I install a trailer hitch and tow with my 2001 Mazda 626 LX? It is a 4-cylinder, automatic sedan. I want to pull a small trailer with a 400 pound motorcycle.|||Hitch weight of 100 lbs or less and total trailer with a couple of bikes 1000 pounds should not hurt the 626 however the automatic transmission should have a larger transmission oil cooler. The Ford CD-4E auto transmission will even fail on a car with out towing anything. Remember ft. wheel drive isn't the best thing for towing trailers
