I pull my 14ft aluminum boat with my 93' nissan 2wd. Truthfully, it gives the truck about all it wants. The boat and trailer really aren't all that heavy, maybe 800 lbs if that. The moral of the story is that my Nissan was made for gas mileage and not towing anything with weight to it. Mine is a manual transmission also, so I dont know about the transmission. Be careful is my best advice.
