Automatic Transmission Cooler problems of the 2017 Toyota Corolla

I own a Toyota Corolla 2017 since 1/14/17. Car shows 2 main issues: 1)- cooling fluid evaporates continuosly or decreases from fluid tank at about 1/4 of in. X month every time I've checked it in. I,first, refilled it once with correct or same fluid. It kept evaporating at the same rate. Then,I reported it to dealership it was sold. 2)- shift lever or gear control; this car comes with cvt automatic trans- mission, every time I shift speed gear and move knob from parking to drive position and vice verse, the shifting doesn't ocurres correctly or got stuck in the previous speed temporarely and then it moves to position I shifted. When car is apllied brake pedal to park car in plain surface areas(parking lots, city streets) and speed gear knob is placed in parking position, car moves back and forths 2 to 3 times and then stop completely. Both issues were reported to dealership. In a programmed service car asked to dealership due to manufacturer's car warranty on June,11th/17 both issues were reported to dealership technician performing car services. According to technician's report and words, cooling fluid tank was refilled to correct levels, computer checking was applied and failures codes weren't found either on the cooling system or automatic transmission system. Technician also reported that farther observation would be needed in case of transmission shifting issues,but it would take my car parked in dealership service areas for 3 hours before he tries any attempt to dissamble any transmission parts or any farther testing. Up to present, either issues haven't been addressed or fixed by dealership's technicians and both issues keep happening.
