Before attempting to repair the clutch, transmission, or related components for any reason other than an obvious failure, identify the problem and the probable cause. Shifting difficulties, such as a high shift effort, a gear clash, or grinding, are symptomatic of a large percentage of any clutch or manual transmission problems. When any of these problems occur, it is necessary to perform a careful analysis of these difficulties.

Before removing a suspected failed hydraulic clutch system, check the reservoir fluid level. The actuator cylinder must be in place when checking the fluid level. If the fluid level is low, fill the reservoir to the specified level with DOT 3 brake fluid GM P/N 1052535 or the equivalent. Do not overfill the system.

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.

If the reservoir requires any fluid, check the hydraulic system components for leakage. A slight wetting of the surfaces is acceptable. Replace the system if any excessive leakage is evident.
