That's an extremely light car or trailer - even a light 16 ft. trailer weighs ~1,600 lbs. and even a late 90's Cavalier weighs 2,600-2,900 lbs. So the average "car on a trailer" figure is closer to 5,000 lbs.

I think the OP's vehicle will handle his proposed trailer weight well, unless heavy wind or steep hills are in play then he may be relegated to slowing down and using 3rd gear at times. FWIW I've heard multiple people say the single most important thing to keeping a 4L60E in one piece is keeping it cool, so an auxilary cooler may be well worth the trouble.
