The clutch master cylinder on a Chevrolet Silverado 3500 is connected to the clutch pedal and delivers hydraulic fluid to the transmission to shift each gear. When the clutch master cylinder goes out, the transmission cant shift into gear, and you wont be able to drive the truck. Fortunately, if you have a few hours of time, then you can change out the master cylinder for a new one and get the truck back on the road.
Step 1
Look underneath the dashboard at the clutch pedal. Unplug the harness from the pedal by hand. Push the clutch pedal down with one hand then squeeze the tabs on the side of the bushing that connects the clutch master cylinder linkage to the pedal to release it from the pedal.
Step 2
Lift the front of the truck with the jack and secure it on jack stands. Locate the connection where the hydraulic line from the clutch master cylinder runs into the transmission. Install the Chevrolet hydraulic line removal tool onto the edge of the fitting then push the line in towards the transmission to release the quick-disconnect fitting holding it onto the transmission.
Step 3
Pop the hood. Locate the clutch master cylinder on the firewall, just to the right of the brake booster. Grip the clutch master cylinder then turn it counterclockwise to release it from the dash. Install the replacement clutch master cylinder into the firewall by tilting it at a 45-degree angle and turning it clockwise in the firewall.
Push the hydraulic line into the transmission and lower the vehicle off of the jack stands with the jack. Look underneath the dash and locate the linkage on the clutch master cylinder. Push in the tabs on the bushing on the linkage then connect it to the pedal.
