My car recently started upshifting and downshifting really hard. Even when shifting from reverse to drive it shifts hard. At first I thought it was a problem with the transmission but I took it to toyota and they said 3 of the engine mounts were bad. Besides that they said the transmission and engine were fine. I swapped out the mounts and was still having a problem although it was hitting a little less hard. Drained the transmission fluid and replaced the filter and fluid and again it was hitting a little less hard but none the less still doing it. If anyone has any insight on this issue your assistance would be greatly appreciated.
