Between 10 and 20 mph occasionally, not always, there is a hard shift that doesn't feel normal. It is usually under light acceleration and conditions. Even trying to mimic it under the same exact conditions, sometimes it will simply not do it. . Sometimes it will be a hard thump. Other times it will feel premature. (shifting before it should) I wanted to believe it is the transition from the launch gear to the cvt but the timing of the transition and the degree of the hard shift even under the same conditions tends to vary considerably.
Vehicle has a very hard shift out of launch "first gear" when low on fuel or the engine is cold. Dealership (sheehy Toyota in fredericksburg va) and could experience the same feeling on light to moderate acceleration. I informed the dealership that the feeling they were experiencing is minor compared to what it usually feels like when driving. They experienced the same thing when driving another 2020 Corolla off the lot with light to moderate acceleration. Then a day later they drove another 20202 Corolla supposedly for another 30 minutes and could not duplicate the hard shift and noted that when driving both the customers car and a new car the shift feeling varied from time to time so there was nothing they would do. They also said they contacted the engineers at Toyota who said that this hard shift feeling was normal. Looks like Toyota is back at it with just deny everything and hope the problem goes away. Very unhappy with my experience especially with how Toyota has handled this so far. I will not go away until they fix this problem.
