This is what Nissan says of the Transmission under powertrain warranty.

All hydraulics are covered under basic warranty only. Powertrain mostly concerns larger items such as driveshaft, differential, transmission, engine.

Just checked my infiniti elite coverage - looks like both the master and slave are covered. I imagine if you have a nissan extended warranty, coverage would be similar.

Having clutch issues: no fluid loss, pedal is not sticking, no additional drivetrain noises, goes into gear fine.

Symptoms: a pop sound when shifting, after there as a much softer clutch pedal, less clutch engagement, some clutch slip.

Going to the dealer tomorrow AM so will report back when they let me know their findings.

Christian, it almost sounds like your clutch is worn. How many miles on the car?

An issue with the CSC or master typically does not result in slippage. If you're in 3rd gear, ~30-35 mph and you nail it, does the rpm increase proportionally to the speed? If rpms shoot up way quickly, then it's definitely a worn clutch. Not covered under warranty unless you can convince them it's due to some other defect.

9,000 miles, if there is something wrong with the pressure plate or slave, it could prevent the clutch from fully engaging. The clutch is definitely not worn, especially since this change happened immediately after that pop during a normal shift.

Indeed. At 9K miles, friction plate should have plenty of life left. Sounds like your clutch wear is secondary to whatever happened originally. Good luck!

Happened to me today. Driving to the gym and clutch started to feel a bit weird, but thought my seat was just misadjusted and didn't think about it. Coming home, clutch fell right down and then the engagement was on the floor, and then nowhere at all, and wouldn't return. Stopped at a red light and couldn't get moving again :(
Clutch fluid level looked fine, might have even been above max, but looked very dirty.

Once I figured out how to drive without a clutch, limped to the nearest dealership and it's sitting there now waiting to be looked at.

Clutchless shifting and using the starter to get moving (while clutch pedal is to the floor)?

Yup... and not stopping at stop signs

Good news, They're replacing the master, slave, and hoses all under warranty.

Got an Altima 2.5S for my troubles.

Happened to me tonight. I noticed that the clutch had been feeling funny but thought it was just because it has been so damn hot here. Well driving normally, slowing for a stop sign, push clutch and lost all pressure. The pedal was stuck to the floor. Behind me was a trail of clutch fluid and fluid is leaking from inside the bell housing. Ill be calling Nissan in the morning and getting it sorted out. I am still under factory bumper to bumper warranty until Sept.

dragonbreath - Be glad you're still under warranty. I'm 3 months past the warranty with 21,000 miles and the CSC went out this weekend. Dealer wants almost $1000 in parts and labor to fix it.

^^I'd take it to a local shop and install one of the heavy duty CSC's available. Probably a good idea to replace the master too...?
