Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, GM's preferred method to bleed the system, is to use a vacuum bleeder, below is a bulletin from GM about it. If you do not have access to a vacuum bleeder, your in for a lot of hassle as the systems are really a bear to get to bleed manually. The manual way is the same as bleeding brakes, except your only bleeding one cylinder. If you have access to a brake fluid can that pumps the fluid out of the can to fill the master let me know as I have one other method that works better than the regular way. Thanks
This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 01-07-31-002A (Section 07 -- Transmission/Transaxle).
This bulletin is being issued to inform dealers of an improved procedure to aid in the ease of bleeding the clutch hydraulic system for the above listed vehicles. This procedure can be used anytime air is introduced into the hydraulic system. Following this procedure may also reduce the number of unnecessary parts replaced for low clutch pedal reserve and high shift effort.
Important: Brake fluid will deteriorate the rubber on J 43485. Use a clean shop cloth to wipe away the fluid after each use.
Caution: The vehicle will move if started in gear before the Actuator Cylinder is refilled and operational. Start the vehicle the first time in neutral to help prevent personal injury from vehicle movement and see if the transmission will shift easily into gear.
