The vehicle is a great vehicle. However, I have been noticing that my transmission fluid temperatures rise quickly, whether on the highway or when driving around town. I spoke to a Toyota dealership, and they told me that the proper operating temperatures for the transmission are between 167 degrees and 185 degrees. the temperatures on my transmissions have gotten past 200 degrees. I feel that it is a safety issue because if I am towing or driving long distances or in stop-and-go traffic over time, the transmission may cause a breakdown and then I will be stuck in the middle of traffic. It is a pretty big and heavy vehicle to push off the roadway, and way too expensive to allow someone to push me off of the roadway.
