What is the year, make, and model of your vehicle?





Customer: replied 8 years ago.
1999 Jeep Cherokee 4.0L engine.
Expert:  brownjeff replied 8 years ago.

Loosen the slave cylinder on the transmission. Have someone push the clutch in while you watch the rod on the transmission. If the rod moves then there is a problem with the pressure plate. If the rod doesn't move then you have a bad master cylinder/slave cylinder which are serviced as one on this model.

This was a question from my son that is stuck on the road in Virginia. We thought the slave cylinder was internal to the clutch. Is it mounted external on the transmission?
Expert:  brownjeff replied 8 years ago.

It is external.


The clutch master cylinder, slave cylinder and connecting line are serviced as an assembly only. The linkage components cannot be overhauled or serviced separately. The cylinders and connecting line are sealed units. Also note that removal/installation procedures for right and left hand drive models are basically the same. Only master cylinder location is different.


  1. Raise vehicle.
  2. Remove fasteners attaching slave cylinder to clutch housing.

  1. Remove slave cylinder from clutch housing.
  2. Disengage clutch fluid line from body clips.
  3. Lower vehicle.
  4. Verify that cap on clutch master cylinder reservoir is tight. This is necessary to avoid spilling fluid during removal.
