b&m short shifter
 

i recently bought a 98 s14 ..
it came with a b&m shifter
this is the first car i own that has one so i dont know much about them

first issue is that it feels to go in hard compared to the stock one that my dad has in his s14 ... maybe normal idk

second issue .. at higher rpm it rattles .. extremely annoying ...

i was told that both issues are normal

and i have taken it apart and it look a little dry in there ..is it ok to grease the inside parts ?
i come from the aviation industry and we dont particularly like metals rubbing together with no kind of lubricant
