The torque converter is not capable of transferring all of the input power and may lose up to 10% which increases fuel consumption along with transmission fluid temperatures, requiring the fluid to be replaced more often. Watching the ScanGauge, I can see that temp slowly climbs while driving on the freeway. To overcome these losses torque converters are equipped with a lock up clutch that can mechanically lock the engine output to the transmission under certain conditions. However, if necessary, consult your Subaru dealer for inspection. In other words, it's a good idea to inspect or have the unit inspected regularly to avoid any surprises. Send it in for repair.

At those temps recing oil is needed and it needs to be changed alot. There is also a torque converter - to broaden the range of gear ratios and to ensure a smooth start-off. A frustrated customer complained to the NHTSA with the note, Transmission failure. With the small contact area, high pressure, and somewhat bell shaped Variators an unfortunate high pitched whining noise may be generated. It is possible to increase the number of gear ratios to overcome these design limitations, however in doing so the transmission becomes more complex, heavier, and contains more components which also increases opportunities for a component to fail.
