1. Are you supposed to disengage the clutch while shifting into neutral from any other gear because it seems like there is no resistance if I just shift into neutral at anytime, but I don't know if thats good for the transmission or whatever.

2. While stationary and with the car in neutral, I slowly brought the engine up to 3000rpm and back down to idle at 750rpm. It seemed like there was slightly more vibration in the engine at right about 2000rpm and at 750rpm, but you have to listen very close. Is that normal and just some a resonance in the engine at certain speed?

For number 2 your engine will sound different at all engine speeds, its just the way it works, intake lengths are synchronized with certain operating ranges, so even your intake will sound different at different RPMS yet alone your whole engine.

YES SIR!
It's obviously not required but it is certainly good practice. It also saves you from the embarassment of looking like a total amateur when you have friends in the car. :wink:

Well, that's not completely true, you can shift fully without hurting the transmission, it just takes too long for an effective shift. When you shift into neutral you are just releasing the attachment from the transmission to the differential. When you shift into gear you are connecting the selected gear with the differential. If their RPMs don't match up you can get grinding.

If a clutch goes out in a car and you need to drive it somewhere (which is hard to do if you can't idle) then you need to be able to shift without the clutch. If you are in 1st and want to shift to 2nd, put the car in neutral and ease up on the gas. Start shifting into second, but very carefully as you are back down on the accelerator. Keep a little pressure on the stick toward 2nd gear without causing grinding and when the RPMs of the driveshaft and 2nd gear match up you should be able to slide it into gear. This doesn't hurt the car, but this is very easy to do wrong so if you have a working clutch this process is not recommended.
