Interesting as I just rented a Pacifica and was slightly above the max cargo capacity. I found the transmission to struggle at low speeds, but it was fine at highway speeds.
Weird. I thought it behaved extremely well at any speed... though I mainly drove highway through the Rockies. In fact, when I first tested towing a car on a 2-wheel dolly, I had forgot to unset the e-brake on the car. I didn't even notice it was leaving two trails of shredded rubber until I stopped a block later! (Yes, I had to replace the rear tires on that car).
What were you towing (trailer+cargo)? Just wondering if you were more than slightly above max...
