How a Manual Clutch Works

In a manual transmission vehicle, the clutch connects and disconnects the engine from the transmission. A friction disc sits between the engine’s flywheel and a spring-loaded pressure plate. When your foot is off the pedal, the pressure plate clamps the disc against the flywheel and power flows to the wheels. Press the pedal, and a release bearing pushes on the pressure plate springs to free the disc so you can shift gears.

The friction disc is designed to wear, much like brake pads. How long it lasts depends on driving habits, load and traffic. When it wears thin or is damaged by heat or oil, clutch replacement in Glendale, AZ is the fix.

Signs You Need a New Clutch

• Slipping: engine RPM rises but the vehicle does not accelerate to match, especially in higher gears or going uphill
• Burning smell after climbing a grade, towing or heavy traffic
• Clutch engages very high in the pedal travel
• Chatter or shudder when pulling away from a stop
• Hard to shift or grinding into gear, which may mean the clutch is not fully releasing
• Noises that change when you press the pedal, often from the release or pilot bearing
• Stiff, soft or sinking pedal, which may point to the hydraulic system rather than the clutch itself

Why Clutches Wear Out in the Valley

Stop-and-go traffic on Bell Road, Glendale Avenue and the freeways during rush hour means a lot of clutch engagements. Riding the clutch at lights, slipping it to creep in traffic, launching hard, and towing or carrying heavy loads all generate heat. Heat glazes the friction surfaces and can warp the flywheel or crack the pressure plate. Oil leaks from a rear main seal or transmission input seal can also contaminate the disc and cause slipping and chatter.

What a Complete Clutch Replacement Includes

The clutch is located between the engine and transmission, so the transmission or transaxle must be removed to replace it. Because labor is the largest part of the job, we replace the wear parts together so you are not paying for the same labor twice.

• Clutch disc matched to your vehicle and use
• Pressure plate with correct clamping force
• Release (throwout) bearing and, where applicable, the concentric slave cylinder
• Pilot bearing or bushing in the crankshaft
• Flywheel service: resurfacing on solid flywheels in good condition, or replacement when needed. See our flywheel resurfacing page.
• Inspection of seals, including the rear main seal and transmission input seal, to prevent oil contamination
• Hydraulic system check and bleed, and inspection of the fork, pivot and linkage

Dual-Mass Flywheels

Many modern cars and trucks, including a number of diesel pickups and European vehicles, use a dual-mass flywheel to reduce vibration. These have internal springs and are generally not resurfaced. If a dual-mass flywheel is worn, loose or noisy, it needs replacement. Some owners choose a conversion kit with a solid flywheel, which can change noise and vibration characteristics. We will explain the trade-offs for your vehicle.

Clutch or Hydraulics?

Most modern manual vehicles use a hydraulic clutch with a master cylinder and slave cylinder. A leaking or failing hydraulic system can cause a soft pedal, a pedal that sticks to the floor, or a clutch that will not fully release. Sometimes the fix is a hydraulic repair rather than a new clutch. Learn more on our hydraulic clutch repair page.

Heavy-Duty and Performance Clutches

If you tow, have added power, or run a modified truck or performance car, a stock clutch may slip. Upgraded clutches use stronger pressure plates and different friction materials. They hold more torque but can make the pedal heavier or engagement more abrupt. We help you choose a clutch that fits how you actually drive. For bigger builds, see performance transmission builds.

Our Clutch Replacement Process

1. Road test and inspect to confirm the clutch is the cause.
2. Remove the transmission and inspect all clutch components and the flywheel.
3. Resurface or replace the flywheel, and install the new clutch kit, bearings and any needed seals.
4. Reinstall the transmission, bleed the hydraulics and check the fluid in the transmission.
5. Road test for proper engagement, release and smooth shifting.

Driving Habits That Help a New Clutch Last

Keep your foot off the pedal when cruising, use the parking brake on hills instead of holding the vehicle with the clutch, and shift into neutral at long lights. Follow the break-in recommendations for the new clutch, usually avoiding hard launches and heavy towing for the first few hundred miles.

Clutch Replacement FAQ

How long does a clutch replacement take?

It depends on the vehicle. Rear-wheel-drive trucks are often more straightforward than tightly packaged front-wheel-drive or all-wheel-drive vehicles.

Can I drive with a slipping clutch?

Slipping gets worse and creates heat that can damage the flywheel. Have it checked soon, and avoid towing or steep grades.

How much does clutch replacement cost?

It depends on the vehicle, clutch kit and flywheel needs. Call (623) 473-9800 for a free quote, and ask about financing. More details are on our clutch repair page.
