If it has fixed gear ratios, there must be an infinite number of them! Whatever you call it, it the electrically controlled PSD functions as a CVT with a smoothly variable output gear ratio.
At any constant throttle setting the engine maintains a constant RPM to my ears and other senses while speed increases - most noticeable at full-tilt. Nothing at all to suggest a shift to a different fixed ratio as a conventional autotranny does when RPM's peak then fall with each gear change during acceleration.

The Highlander Hybrid does not have a transmission! Really. The planetary gear set (sometimes called Power Split Device) distributes torque between the ICE and traction motor to the driven wheels. The ICE is always in direct-drive. The PSD has fixed ratios and should not be confused with a CVT. The fluid in the PSD is truly marvelous: Toyota's WS (for World Standard). It's good for at least 100,000 miles and is very expensive to replace. An honest dealer will confirm this and, should you have the WS fluid replaced, it would cost about $200 with labor.
