I just did my t5 swap about a week ago and i noticed that it didn't want to go into 2nd. The t5 was just rebuilt and doesn't have more than 300 miles on it. I figured it was just my shifter but i switched out shifters today and its still doing it. It will go into 2nd if i drive slow and i can start off in 2nd but if i'm trying to change fast between 1st and 2nd it grinds. What do yall think it could be?
