hey guys i have a 2003 350z touring that has had some problems with the transmission ive changed out the 1st one because i had problems with 3rd gear grinding only when i push it from 2nd and slam it into 3rd, but now i have about 5k miles on this transmission and when i shift to 2nd 3rd and 5th just driving normally it kinda feels really wierd when going in its not smooth like 4th and 6th, but sometimes when i shift to 2nd i hear a really wierd noice it might be grinding but it doesnt really sound like it should i take my car to the dealership again or is this normal?
