### Preliminary Checks

Notice: Carefully clean the top and sides of the reservoir before opening to prevent contamination of the system with dirt, water, or other foreign material. Remove the reservoir diaphragm before adding fluid. Carefully replace the diaphragm and cover after filling.

Shifting difficulties such as the following conditions indicate a large percentage of clutch and manual transmission assembly problems:

• | A high shift effort

• | Gear clash

• | Gear grinding

• | Transmission blockout

Use the Clutch Diagnosis Chart to assist with clutch diagnosis.

If the reservoir requires any fluid, check the hydraulic system components for leakage. Remove the rubber boots from the cylinder and check for leakage past the pistons. A slight wetting of the surfaces is acceptable. Replace the system if excessive leakage is evident.
