Hello i have a 07 base 6mt with 12.5miles

now question is, when im in either gear slowing down from lets say 4krpm to 2-3krpm i get a quick 1 or 2 second strong vibration from the shifter, all the time my shifter sort of vibrates but not that strong, is this normal?

 

Im pretty sure i understand what you are describing. It is normal, the 03 i had did this and my nismo does it.

 

If your tranny has moving parts while the engine is running, this is NORmL.
