yeah you'll be fine, my buddy is running a stock lq4 w/ a pred tune for engine and trans with a deep pan and tows 20K lbs (that means 26K w/ truck) at least 100 miles a week. Trans has 90K on the clock and hasn't given up the ghost yet.

There are THOUSANDS of 4l80s in service behind big blocks in vehicles that weigh 15,000lbs or more, with no problems. bone stock 4l80s are tougher than people credit them for.
