Possible Nissan OEM clutch system issue - Everyone Read

ImportConvert

As I suspected, there is no problem with the car. When you have the transmission in neutral and the clutch is engaged, everything in the transmission is spinning EXCEPT the output shaft.

That means that all those gears are doing what, 700rpm (I don't know what a 370Z idles at)?

As many of you have noted, the transmission can handle some power. I have taken a look at pictures of the gears online, and they are not puny. They have some mass to 'em.

Then you put it in first and the output shaft is engaged.

Guess what? All the inertia of that transmissions internals spinning at 700rpm hits the rear end as the output shaft comes into play.

Of course it's going to roll forward a foot or two if you whip it from neutral to first. To test this, why don't you crank the car and KEEP the clutch fully depressed. Then shift to neutral, NEVER RELEASING THE CLUTCH, keep it there 60 seconds, and shift into 1st. I bet dollars to doughnuts 0 lurch. Now put it back in neutral, let the clutch out, and after 3 or 4 seconds stab the clutch and jam second. Roll.

*This is as far as I have read in this thread, so if someone already said all this jazz, sorry to re-hash.
