I am an owner of a 2004 Tundra SR5 Double Cab and have the original window sticker verifying that a transmission cooler is a standard part for this vehicle. However, after several months of arguing with the dealership they finally agree there is no transmission cooler installed on my truck. They are in the process of working with the local Toyota Rep., but have made mention that this is a factory only installed part. I called Toyota's customer support and they say the same. This does not make much sense to me as I know of other trucks where this part is installed after market. Can someone point to strong evidence that this part can in fact be installed after market or point me in the right direction for what my rights are and what recourse I have considering that the final answer might be it cannot be installed once the truck leaves the factory. I got the truck for the towing capacity and without this part my towing is very limited.

Thanks in advance.
