Question:
Im concerned about my 2001 Tundra Access Cab Limited 4X4 transmission overheating when towing a 5256 GVWR travel trailer. I purchased the truck new and it has a towing package. There is a 6inch wide x 10inch tall transmission cooler installed in front of the radiator and a/c condenser that was factory installed. Should this be adequate? Is there a way to install a transmission temperature gauge, and if so what is the expected normal and maximum temperatures?

Expert Reply:
Since your Tundra is equipped with the tow package and has a dedicated transmission cooler, so long as you stay within the truck's rated towing capacity you should be fine.
If you have the physical space available for a larger cooler and want to add some safety margin, you could replace the existing cooler with a larger and more efficient one. The highest-efficiency cooler we offer for your Tundra is the Derale # D13503 which is a Class III cooler that measures 11 x 8-3/4.
You also have the option of adding another cooler to the vehicle, such as a frame-rail-mount type like # D13262. This would work in tandem with the OEM cooler.
Typically a transmission cooler will reduce operating temperatures between 10 and 20 degrees. The usual range of operating temperatures for a transmission is generally 180-190 F. We do not offer a stand-alone temperature gauge for your truck but you might instead use a hand-held type thermometer that will allow you to check the transmission temps before and after your new cooler. It would also allow you to do so while you're towing.
