I had a Monte Carlo once with a 4T60E transmission (technically a "hydromatic" as well). Never broke down, but it changed gear whenever the proverbial "Butterfly In Brazil" flapped it's wings. And the torque converter doesn't lock when accelerating, only for the final gear. This type of transmission is comfortable but leads to the snot feeling JJ described earlier.

LOL, that's a variation on a theme pioneered by the Dutch car maker DAF, called the variomatic, except most people called it 'jarretel drive' (garter belt drive)
you are thinking of Nissan's CVT. Toyota's is different: a planetary gear, with a gas engine on the sun gear, a (brushless) electric motor on the planets, and a second motor on the ring (which is also the final drive).

Low gear: When accelerating at low speeds in normal operation, the engine turns more rapidly than the wheels but does not develop sufficient torque. The extra engine speed is fed to MG1 acting as a generator. The output of MG1 is fed to MG2, acting as a motor and adding torque at the driveshaft.
High gear: When cruising at high speed, the engine turns more slowly than the wheels but develops more torque than needed. MG2 then runs as a generator to remove the excess engine torque, producing power that is fed to MG1 acting as a motor to increase the wheel speed. In steady state, the engine provides all of the power to propel the car unless the engine is unable to supply it (as during heavy acceleration, or driving up a steep incline at high speed). In this case, the battery supplies the difference. Whenever the required propulsion power changes, the battery quickly balances the power budget, allowing the engine to change power relatively slowly.
