  What happens before your transmission goes out?

  There are often warning signs or symptoms that indicate a potential problem before a transmission fails completely. These signs may vary depending on the specific issue affecting the transfer, but some common signs that the transfer may be failing include:
  ① Gear slipping: One of the most common signs of transmission failure is that the transmission slips out of gear or shifts unexpectedly while driving. You may notice acceleration lag, rpm fluctuations, or a feeling that the vehicle is struggling to get into the right gear.
  ② Delayed or rough shifting: If you experience delayed or rough shifting, where the transmission hesitates before shifting or shifts suddenly with a noticeable jerking or clunk, it may indicate a problem within the transmission.
  ③ Abnormal noises: Strange noises coming from the transmission, such as whining, grinding, buzzing, or clanging, may indicate worn or damaged internal components, such as gears, bearings, or synchronizes.
  ④ Fluid leaks: Transmission fluid leaks are a common sign of transmission problems. If you notice red or brown fluid collecting under your vehicle, the leak must be addressed immediately to prevent damage to the transmission.
  ⑤ Burning smell: A burning smell from the transmission or engine compartment may indicate that the transmission fluid is overheating, which may be caused by internal friction or insufficient cooling. Overheating can lead to accelerated wear and potential transmission failure.
  ⑥ Dashboard warning lights: Many modern vehicles are equipped with on-board diagnostic systems that can detect transmission problems and illuminate warning lights on the dashboard, such as the check engine light or transmission warning light. If these lights appear, it is crucial to have the vehicle inspected by a qualified mechanic.
  ⑦ Difficulty shifting into gear: If you are having difficulty shifting gears, whether it is an automatic or manual transmission vehicle, it may indicate a problem with the clutch (manual transmission) or internal components of the transmission.
  If you notice any of these signs or symptoms, they must be addressed immediately to prevent further transmission damage and avoid costly repairs or replacements. Ignoring transmission problems can lead to more serious problems and could leave you stranded on the road. If you suspect a transmission problem, it is recommended to have the vehicle inspected by a qualified mechanic as soon as possible.

  What is a transmission tune up?

  A transmission tune-up, also known as transmission service or maintenance, involves inspecting and performing various procedures to ensure the proper operation and longevity of your vehicle's transmission system. While the specific tasks involved in a transmission tune-up may vary depending on the make, model, and condition of the vehicle, typical components of a transmission tune-up can include:
  ① Fluid inspection and replacement: It is crucial to check the transmission fluid level and condition. If the fluid level is low, it may indicate a leak, and degraded or contaminated fluid may need to be replaced. In some cases, a thorough fluid flush or fluid exchange may be recommended to remove old fluid and contaminants.
  ② Filter replacement: For vehicles equipped with automatic transmissions, replacing the transmission filter is usually part of the transmission adjustment. The filter helps remove dirt, debris, and contaminants from the transmission fluid, preventing them from circulating in the transmission and causing damage.
  ③ Transmission Pan Inspection: Removing the transmission pan to inspect for debris, metal shavings, or signs of excessive wear is another common aspect of transmission tuning. Pots and magnets that collect metal particles may also need to be cleaned.
  ④ Adjustment and calibration: Some transmission systems may require adjustments or recalibration of components such as the throttle linkage, regulating valve or shift solenoid valve to ensure smooth shifting and optimal performance.
  ⑤ Seals and gasket inspection: During the transmission adjustment process, it is crucial to check for leaks and the condition of the transmission seals and gaskets. Damaged or worn seals and gaskets can cause fluid leaks, which if not addressed promptly, can lead to transmission issues.
  ⑥ Diagnostic scan: Using specialized equipment to perform a diagnostic scan to check for any stored error codes or transmission-related issues can help identify potential problems before they escalate.

  Do you check transmission fluid when the car is running?

  No, it is generally not recommended to check the transmission fluid while the car is running. Here’s why:
  ① Safety issues: Checking the transmission fluid while the car is running may pose a safety risk because you need to access the transmission dipstick or oil filler port while the engine is running, which involves being near moving parts that may cause injury.
  ② Accuracy: It is best to check the transmission fluid level and condition with the engine off to ensure an accurate reading. Running the engine affects fluid levels and temperatures, possibly giving misleading readings.
  ③ Transmission design: The transmission oil dipstick of some vehicles can only be used when the engine is turned off. Due to design limitations, trying to check the fluid while the engine is running may not be possible.
  ④ Transmission damage: In some cases, running the engine while the vehicle is stationary (idling) for a long time may cause the transmission to overheat, especially if the car has poor ventilation or the transmission cooler is not working properly.
