SERVICE MANUAL UPDATE
The 1988 Grand Prix models with manual transaxles use a one-piece hydraulic line for clutch operation. Whenever powertrain components are lowered for any reason (removal, access to other components, etc.), the clutch actuator must be removed from the clutch housing using the attached procedures. Also, the clutch hydraulic system cannot be bled. If a component fails, the entire system (master cylinder, hydraulic line and clutch actuator) must be replaced as an assembly.
