So, i have a 94 i6 4.0 with an aw4, and np231. Anyway, i was looking at doing a custom shift **** like a few others have done, does anyone have a detailed write up about it? Also a more pertinent question, is the shift button on the left side on the shift a mechanical linkage or is it simply and electric switch. I Ask because putting a different switch in is easy, but i dont want to mess with any sort of mechanical linkages. Thanks y'all
