Clutch chatter, clutch slippage and difficulty getting transmission into gear when stopped.
Usually if there is no indication of clutch wear, such as slippage, yet with the clutch completetly depressed it's hard to engage gears and the clutch engages very quckly
Most likely the clutch is shot. When the clutch plate can't engage with the transmission there will be slippage between the engine and the drive wheels.
You will wear your clutch prematurely. With no play, it means that there is lack of pressure on the clutch plate thus allowing it to slip; slippage causes wear.
Trouble code P0811 means: Excessive clutch slippage
Clutch slippage can cause an engine to overheat by running the engine at higher rpm's than what it is recommended for the motor. Excessive heat in the engine can cause the head gaskets to leak building up heat in the motor. There are inexpensive kits to test whether your headgasket is leaking or not.
Excessive converter clutch slippage, either a bad solenoid or converter needs to be replaced. I would do both.
Uniform wear theory is used in clutch design to ensure that the contact surfaces of the clutch components wear evenly. This helps to maintain consistent and predictable performance over the lifespan of the clutch. By design, the uniform wear theory aims to minimize uneven wear that can lead to slippage, vibration, and premature failure of the clutch system.
Check your fluid. If it's brown, instead of red... or it smells burnt... chances are the third and fourth gear clutch packs are in need of replacement.
Clutch release bearing, if installed in this particular Nissan transmission (I don't know the specifics of this particular transmission), probably needs to be replaced.

Well at least nn a car, you need a clutch because the engine spins all the time and the car wheels don't. In order for a car to stop without killing the engine, the wheels need to be disconnected from the engine somehow. The clutch allows us to smoothly engage a spinning engine to a non-spinning transmission by controlling the slippage between them...
