Like any mechanical system, your car’s transmission is extremely susceptible to wear and tear over time. Detecting transmission issues early can save you from costly repairs and prevent unexpected breakdowns on the road. One of the most effective ways to achieve this is through regular visual inspections. Read on to know a step-by-step guide to carry out a visual inspection without any hassle.

Why is Visual Inspection important to detect transmission issues?

Conducting a visual inspection allows vehicle owners or mechanics to identify visible signs of trouble, such as fluid leaks, external damage, loose connections, and worn components. By spotting transmission fluid leaks, which are often indicated by reddish stains under the car or around the transmission case, one can prevent fluid loss and subsequent damage to the transmission.

Additionally, a thorough visual inspection can reveal external damage, like cracks or dents on the transmission casing, that might compromise its integrity. Loose or disconnected transmission lines can also be identified during inspection, helping to prevent fluid flow issues and overheating. Moreover, a visual inspection allows for the early detection of worn or broken components, which, when addressed promptly, can prevent more significant problems and costly repairs. Regular visual inspections not only contribute to the overall health and longevity of the transmission but also ensure a safer and more reliable driving experience.

Step-by-Step Instructions to carry out a Visual Inspection:

1. Prepare Your Vehicle:

  • tag Park your car on a flat, level surface and engage the parking brake to ensure the vehicle remains stationary during the inspection.
  • tag Turn off the engine and allow the car to cool down to avoid contact with hot surfaces.

2. Locate the Transmission:

  • tag Refer to your vehicle's owner's manual to find the location of the transmission. In most cars, it is situated between the engine and the driveshaft or near the centre of the vehicle's undercarriage.

3. Check for Leaks:

  • tag Inspect the area around the transmission for any signs of fluid leaks. Transmission fluid is typically red or reddish-brown in colour.
  • tag Look under the car for puddles or drips of fluid, which might indicate a leak.

4. Examine the Transmission Case:

  • tag Begin visually inspecting the transmission case for any visible damage, such as cracks, dents, or signs of impact.
  • tag Pay attention to the seals and gaskets on the transmission case, as they can be a common source of leaks.

5. Inspect Connections and Hoses:

  • tag Ensure all transmission lines, hoses, and connections are securely attached and free from any signs of wear or damage.
  • tag Check for loose fittings or clamps, which can cause fluid leaks and affect transmission performance.

6. Verify the Fluid Level:

  • tag Locate the transmission dipstick in automatic transmission) or plug (manual transmission) under the hood.
  • tag Pull out the dipstick or remove the plug and check the fluid level. The fluid level should be within the recommended range.

7. Inspect the Transmission Mounts:

  • tag Look for the transmission mounts, which secure the transmission to the vehicle's frame.
  • tag Check for any signs of damage or excessive wear in the mounts, as they can affect the stability of the transmission.

8. Observe for Unusual Sounds or Odours:

  • tag During the inspection, listen for any unusual sounds coming from the transmission area, such as whining or grinding noises.
  • tag Also, pay attention to any unusual smells, as burnt transmission fluid can produce a distinct odour.

9. Take Notes and Document Findings:

  • tag As you conduct the visual inspection, take notes of any issues or findings you observe.
  • tag Document any leaks, damages, loose connections, or abnormal sounds to aid in further assessment or discussions with a professional mechanic.


By following this step-by-step guide, you can keep your transmission in its optimised condition. By identifying visible signs of trouble such as fluid leaks, external damage, loose connections, and worn components, you can prevent minor issues from escalating into costly and potentially hazardous problems.
