Towed our camper for first time. Tv max 5000lb and camper single axle 4000lb. On return trip, noted an odd smell when we would stop at lights. ( no warning lights and did not overheat). We took it to mechanic who found the transmission fluid had become co taiminated and burned (was drained and replaced in January prior to towing and it had the atf added when purchased. Mechanic drained and filled twice to get rid of odor and suggested we take it to dealer (appt is Monday). If we did tow too much weight, is this what we would have seen? If we decrease weight, is it safe to tow at some point? Hoping thereโs an issue with the car but if thereโs not I think the only answer is too much weight. We r attempting to get firm measurements of weight but kind of hard when canโt pull and need to wait for someone to help! Any suggestions would be appteciated
