If it has been towed, you must have checked the fluid and saw that it was black or dark and had a burnt smell, correct? Now at least if your told it is skot and needs work it is no tale of a problem that hasn't even occured.
The cooler is either built in to the radiator tank, or seperate and mounted on or near the radiator, looking like a small heat exchanger. A small radiator for transmission oil to cool off.
The temperature gets so hot in the trans, it needs to get rid of this heat properly, or failure will occur, especially with a large 4WD powertrain.
So it is tested and cleaned with an electric pump and its lbs of pressure that is required for cleaning is used to determine its flow.
No use putting a new unit in and having any pre-mature failure from heat. Either ask them to blow it out and clean it with clean degreasing fluid, or have a new one installed. One that has better heat transfer for a lower temperature at operating speeds. I want you to have it fixed once, and stay fixed for a long time. OK
