What are you using for a gear oil. I used Valvoline 85w140 in mine and my shifts were not notchy at all. I had no problem no lift shifting or shifting normally. Once the oil warms up it was smooth as butter. The positioning of 5 gear was what took getting used to. 5th is very hard to find quickly and sometimes even when shifting slow. Its just in A weird spot. Enjoy the car. If the trans is feeling proper i would try the Valvoline oil man. Seriously, its got a lot of cusion and still maintains very smooth shifts.
