  Is a transmission flush better than a change?

  Whether it's better to flush your transmission or change your transmission fluid depends on a variety of factors, including the vehicle, its maintenance history, and the condition of your transmission fluid. Here are the main differences:

  Transmission Fluid Change:
  Procedure: When changing the fluid, replace only a portion of the transmission fluid, usually the amount that drains from the transmission pan. This is usually done during routine maintenance.
  Advantages: It helps remove some old fluid and contaminants, improving fluid quality.
  

  Transmission Flush:
  Procedure: A transmission flush involves using specialized equipment to pump out the old transmission oil and replace it with new oil at the same time. The purpose of this method is to replace a higher proportion of the old fluid.
  Advantages: It removes contaminants and old fluid more efficiently, providing a more complete exchange.

  
  

  Precautions:
  Fluid Condition: If your transmission fluid is in relatively good condition, a fluid change may be enough. If the fluid is old, contaminated, or showing signs of problems, flushing may be recommended.
  

  Vehicle Manufacturer Recommendations: Some vehicle manufacturers have specific recommendations for fluid exchange methods. It is important to follow the guidelines in the user manual.

  Is it good to flush automatic transmission fluid?

  Flushing automatic transmission fluid is a controversial topic in the automotive industry. While some experts believe that proper flushing can help remove contaminants and extend the life of your transmission, others warn that over-flushing can remove debris and cause problems.
  Proponents argue that controlled flushing with appropriate equipment can effectively replace old fluid and remove accumulated debris, thereby promoting better transfer performance. However, critics argue that power flushing can cause problems and possibly damage if done incorrectly.
  It is crucial to follow the manufacturer's recommendations and use the correct methods and equipment for your specific vehicle. Regular maintenance (such as fluid changes) is generally considered beneficial, but the decision to flush should be based on your vehicle's needs and the advice of a qualified mechanic.

  What is the downside of transmission flush?

  While a transmission flush can provide benefits, the procedure also has potential disadvantages or risks:
  ① Cost: Transmission flushes are typically more expensive than standard fluid changes because they require additional equipment and time.
  ② Equipment quality: The effectiveness of transmission flushing depends on the quality of the equipment used. Low-quality machines or improper procedures may not completely remove contaminants.
  ③ Fluid compatibility: Using the wrong type of transmission fluid or inferior fluid during the flushing process can cause problems. It is crucial to use the fluid recommended by the manufacturer.
  ④ Remove particles: The forceful nature of flushing may remove accumulated particles from the gearbox, which may cause blockage of narrow passages.
  ⑤ Potential damage: If the transmission is already in poor condition, flushing may accelerate the failure of worn parts. It is important to evaluate the condition of your transmission before deciding to flush it.

  Do car manufacturers recommend transmission flush?

  Car manufacturers often have different recommendations for transmission flushing. Some manufacturers may recommend regular transmission fluid changes or flushes as part of their scheduled maintenance program, while others may claim that their transmissions are "sealed for life" and do not require such service.
  
  Be sure to refer to the specific maintenance guidelines provided in your vehicle's owner's manual. Following the manufacturer's recommendations ensures you maintain your warranty and optimizes your vehicle's performance and longevity.

  What will ruin fuel injectors?

  Several factors can cause an injector to become aged or damaged. Here are some common problems that can damage fuel injectors:

  ① Contaminated fuel: Poor-quality or contaminated fuel may contain impurities, debris or water. These contaminants can clog the small openings in the fuel injectors, affecting their performance.

  ② Low-quality fuel filter: A faulty or clogged fuel filter can allow debris and contaminants to enter the fuel injectors, causing damage over time.

  ③ Fuel additives: While fuel additives (such as injector cleaners) may be beneficial when used as directed, excessive or improper use may cause injector damage. Always follow the manufacturer's recommendations.

  ④ Incorrect fuel pressure: The fuel injector operates within a specific pressure range. Fuel pressure that is too high or too low will affect its functionality. Insufficient pressure may result in poor atomization, while too much pressure may damage injector components.

  ⑤ Carbon deposits: Over time, carbon deposits will accumulate on the fuel injector nozzle, affecting the fuel injection pattern.This can be caused by incomplete combustion, poor fuel quality, or prolonged idling.
  ⑥ Abrasive particles: If abrasive particles enter the fuel system, they may cause wear and damage to the injector components.
  ⑦ Overheating: If the engine is running too hot, the fuel injector may overheat. This can cause internal damage and affect the injector's ability to function properly.
  ⑧ Electrical problems: Injector circuit problems (such as wiring problems or connector failures) may cause unstable injector performance.
  ⑨ Corrosion: Corrosion is usually caused by water in the fuel or exposure to corrosive elements and can damage injector components over time.
