Preliminary Checks
Identify the problem and the probable cause before attempting to repair
the following components for any reason other than obvious failure:
• | The transmission assembly |
• | Related hydraulic components |
A large percentage of clutch and manual transmission problems include
the following conditions:
Carefully analyze the problems with the aid of the diagnostic tables.
Before removing what you suspect to be a failed hydraulic clutch system,
check the reservoir fluid level with the actuator cylinder in place. Fill
the reservoir to the specified level with GM Delco Supreme No. ll® Brake
Fluid (GM P/N 1052535), or equivalent fluid, that meets the DOT
3 specifications. Do not overfill the system.
If the reservoir requires any fluid, check the hydraulic system components
for leakage. Remove the rubber boots from the cylinders, checking for leakage
past the pistons. A slight wetting of the surfaces is acceptable. Excessive
leakage requires replacement of the system.
