double clutching is just if the shifter won't go into gear the first time,
let the clutch out, put it in and the shifter goes in with ease. I have
problems with this in my 2000 frontier. Nissan has made notches that the
shifter has to perfectly line up or it won't go in, so you end up letting off
the brake and then it slips in. Not a good thing all the time, I have a hard
time putting it into first when I am slightly rolling! sometimes I have to
go in 2nd gear to start out, or stop completely then put it into first.
Its goofy!
