How Manual Transmissions Work - Manual transmissions let drivers manually shift between gears while controlling engine power and speed. Key components include:

• Clutch – connects/disconnects engine power
• Flywheel & Shaft – deliver engine output
• Gear Selector Fork – moves the gears
• Gears & Collars – transmit power to the drive wheels

Manual Transmission Service Is Essential

Manual transmission fluid degrades over time. If left unchanged, it can lead to poor shifting, gear wear, and even transmission failure.

Signs of transmission trouble include:

• Transmission Slipping Gears
• Difficulty Shifting Gears
• Transmission Popping Out of Gear
• Transmission Fluid Leaks
• Clutch Slipping or Not Engaging
• Transmission Grinding or Unusual Noises

If you notice any of these transmission issues, don’t wait—your manual transmission may need a fluid change, a reseal, or clutch service.
