The clutch will not engage ,you will not be able to shift./// the clutch will not (disengage ) making it almost impossible to shift gears
Clutch slave cylinder is leaking fluid or the connector rod or cable from the clutch pedal is disconnected or broken. Depends on the make and model of the vehicle to know the exact setup of your clutch.
your clutch may not be fully engaging
Clutch is not adjusted properly.
I would suspect a weak clutch slave cylinder or clutch master cylinder which may be preventing the clutch from disengaging fully; The slave cylinder is connected hydraulically to the clutch master cylinder. The clutch master is where you add fluid.
The function of the clutch is to separate the drive train so that the gears can be changed without being damaged.
BAD clutch slave cylinder, wore out clutch and pressure plate.
Not 100% sure on an excel, but where is it leaking? If your car has no clutch fluid then you will not be able to change gears, I would check the seals on the master/slave cylinder, as that is one of the more common places clutches leak.
When you are shifting gears, your RPMs will go down because your clutch is being pressed. If your RPMs don't go back up when you release your clutch, you should see a mechanic.
The most common cause for a transmission not to shift into certain gears is low transmission fluid. Another cause is a broken shifting fork in the transmission.
A faulty slave cylinder will not cause your clutch to slip. The slave cylinder is made up of a housing and a rod. The rod pushes the throwout lever against the throwout bearing, that push the teeth on the clutch housing causing the clutch to disengage and you are allowed to shift the gears. When a slave cylinder fails it makes it difficult for you to shift gears. When it completely fails you will not be able to change gears at all for the most part. I sincerely hope this helps you. www.subarushirt.com The only exception would be if the slave cylinder managed to leak fluid onto the clutch disc.
Check (or have someone check) the clutch fluid reservoir. The fluid may be low.
