Possible Nissan OEM clutch system issue - Everyone Read

jordan3720 · 09-10-2011, 10:13 PM

I experience a similar problem to the one described here. When I'm slowing down to stop at an already very slow speed (about 5mph or less), when I press the clutch pedal and shift into neutral, I hear a loud clank, and the car lurches forward. Could this problem be relative to the shifting into first lurch and thud?

Strangely, I have always had a thud when shifting into reverse. Going into first is sometimes very difficult (embarrassing at stop lights) and I have to go back to neutral, clutch out, clutch in, then back into first and it usually works fine. I'm pretty used to that though b/c my old mazda3 and 330ci did this too. There isn't any lurch forward that I can detect but I'll try on a more level surface.

This is a bit off topic but the idea about realigning the shift gate got me thinking. My upshifts into 2nd were always very notchy and sometimes downright gritty for the first 4k miles. The only reason it got better was because I learned by accident that if I move the shifter closer towards the drivers side as I'm engaging 2nd the notchyness is almost eliminated.

Before, I would engage 2nd with more of a diagonal motion towards the rear and away from me. Now I pull the shifter almost straight back at first then, a sort of jog to the right to seat it in gear. Sounds ridiculous I know but it works. It seems like that particular issue could be related to the shift linkage and gate and not so much the transmission itself. OT rant over.

the reason you are getting a thud is becaue you are going too slow and the timing on the car is fighing the gear. try pushing slightly on the stick when slowing using the break and it will "slip" out of gear. normally it is about at idle that this happens because the computer try's to set the idle while your engine speed is decelerating. or just tap the gas verly lightly and give the stick a easly push to neutral and tada! there is always a point when you accelerate and let off that the gears do not completely touch and thats what you are creating.
