Possible Solutions

If you’re towing a heavy load make sure the vehicle is rated for that load. If the load is too heavy, the transmission cooler may not be able to keep the transmission fluid temperature down. An overheated transmission/transaxle won’t last long. Next, make sure that the cooler isn’t restricted by any debris and that the lines aren’t pinched or leaking. If the transmission cooler is equipped with a cooling fan, make sure it’s operating properly. If the transmission fluid smells burnt or is dark in color, perform a transmission fluid flush. If the transmission fluid level is low, top it off and check for leaks. Note: An overheated transmission can expel fluid out of the vent or out of the torque converter seal.
