Product Details

The CSC product line focuses on clutch hydraulic components for power transfer between the engine and transmission. This slave cylinder is positioned outside the transmission bell housing and works by actuating the clutch fork, which releases the clutch through the mechanical release bearing. FTE 3100921 is a practical replacement for manual transmission repair work where accurate hydraulic movement and consistent clutch release are required. This part cross-references Monroe Shocks & Struts (e.g., D151042, D151042BAG) for the same application.

Common Problems This Part Can Address

• Hard or inconsistent clutch pedal feel
• Clutch not fully disengaging during shifts
• Hydraulic leakage at the slave cylinder
• Difficulty selecting gears in a manual transmission
• Reduced clutch release travel

Installation Notes and Tips

Confirm bore diameter, mounting style, and hydraulic connection before installation. Because this unit is not fluid filled, the clutch hydraulic system should be bled after installation to remove air and restore proper pedal operation. Verify the pin and release mechanism alignment during assembly, and inspect the clutch fork, master cylinder, and hydraulic line for wear while servicing the system. The FTE 3100921 should be matched to the vehicle’s original manual transmission configuration, including Honda Civic and Toyota Corolla applications where specified by the catalog.

Quality Assurance

FTE CSC components are built with OEM-oriented engineering and transmission-system expertise. The 3100921 clutch slave cylinder reflects that approach with a focus on accurate hydraulic actuation and reliable replacement performance for manual transmission service.
