Does Your Transmission Need Service or a Rebuild? A complete transmission failure can leave your vehicle undrivable and result in a high repair bill. To avoid that, it’s important to understand the early signs of transmission trouble. Here are two common indicators every driver should watch for:

Check the Transmission Fluid - Regularly inspecting your transmission fluid can help you catch problems early. Healthy fluid should be reddish, clear, and have a slightly sweet smell. If it’s brown, thick, or has a burnt odor, it’s time for a transmission change?

Also check the transmission fluid level using your vehicle’s dipstick. Low levels often indicate a leak — transmission fluid doesn’t burn off like motor oil. Look for spots under your vehicle or signs of fluid around the transmission housing.

Poor Transmission Shifting or Slipping Gears - Your car should shift gears smoothly and without hesitation. If you experience slipping, delays, or jerky transitions, especially when shifting from Park to Drive or while accelerating, your transmission may need attention. Manual and automatic transmissions show symptoms differently, but both require immediate inspection when performance drops.
