  How do you dispose of gearbox oil?

  Disposal of transmission fluid (also known as gearbox fluid) is important to prevent environmental hazards. The following are general guidelines for proper disposal:
  ① Check local regulations: Different regions may have specific regulations regarding waste oil disposal. Please check with your local environmental agency or city council to learn about the rules and guidelines that apply to your area.
  ② Recycling centers: Many recycling centers accept waste oil for recycling. Some auto parts stores, service stations or government-run collection centers may have waste oil disposal programs. Contact these agencies to ask about their procedures.
  ③ Authorized collection centers: Some places have authorized collection centers that specialize in collecting waste oil. These facilities are capable of handling and properly disposing of waste oil in an environmentally friendly manner.
  ④ Reuse or Recycle: If the oil is relatively clean and uncontaminated, you can reuse it or take it to a recycling facility that accepts used oil for reprocessing. However, make sure the oil is not mixed with other substances such as solvents or chemicals.
  ⑤ Avoid Improper Disposal: Never pour used oil onto the ground, storm drains, or general household trash. Improper disposal can lead to environmental pollution and damage.

  Does transmission fluid flow through torque converter?

  Yes, transmission fluid flows through the torque converter in an automatic transmission system. The torque converter is a key component that plays a vital role in transferring power from the engine to the transmission. It is a fluid coupling device that allows the engine to continue running when the vehicle comes to a complete stop and provides torque multiplication to assist acceleration.
  Here is a brief overview of how transmission fluid flows through the torque converter:
  ① Transmission pump:
  The transmission pump is typically driven by the engine and circulates transmission fluid throughout the transmission system.
  ② Torque converter:
  The torque converter consists of an impeller, turbine and stator. Transmission fluid is pumped by the transmission pump to the impeller, causing it to rotate.
  ③ Fluid flow:
  As the impeller rotates, it creates a flow of transfer fluid that flows toward the turbine.
  ④ Torque multiplication:
  The flow of fluid from the impeller to the turbine creates torque multiplication, allowing the transmission to efficiently transfer power from the engine to the transmission.
  ⑤ Transfer of power:
  The torque converter helps transfer power from the engine to the transmission, allowing the vehicle to move.
  ⑥ Return flow:
  After passing through the turbine, the transmission fluid returns to the impeller, completing the cycle.

  Does transmission fluid circulate while idling?

  Yes, transmission fluid usually circulates even when the vehicle is idling. The transmission pump is usually driven by the engine and is responsible for circulating transmission fluid through the transmission system.As long as the engine is running, the transmission pump is activated, providing the necessary hydraulic pressure to operate various components within the transmission.
  
  At idle, the transmission is still engaged and fluid circulates to lubricate moving parts, transfer power between the engine and transmission, and promote smooth shifts. Continuous circulation of transmission oil is essential to cool, lubricate and ensure proper operation of the transmission.
  
  It is important to note that fluid circulation rates may vary based on factors such as transmission design, temperature, and specific operating conditions. Some vehicles may have additional systems, such as a transmission cooler, to help regulate the temperature of the transmission fluid during circulation.

  Why is my transmission fluid not circulating?

  There are a number of reasons why there may be insufficient transmission fluid circulation in your vehicle. This is a critical issue that can result in poor transmission performance and potential damage to transmission components. Here are some possible reasons why transmission fluid is not circulating:
  ① Low transmission fluid level:
  Low fluid levels can prevent normal circulation. With the engine running and the transmission in neutral or park, use the dipstick to check the transmission fluid level. If the fluid level is below the recommended range, add the appropriate fluid.
  ② The transmission filter is clogged or clogged:
  The transmission filter is responsible for trapping debris and contaminants in the fluid. If the filter becomes clogged, it restricts fluid flow. Consider checking and replacing your transmission filter as part of your regular maintenance.
  ③ Transmission pump failure:
  The transmission pump is responsible for circulating fluid through the transmission. If the pump is damaged or malfunctions, it may impede fluid circulation. A faulty pump may need repair or replacement.
  ④ The transmission cooler pipe is blocked:
  Transmission coolers are designed to cool transmission oil. If the cooler lines are clogged or restricted, fluid flow and circulation may be affected. Check the cooler lines for any obstructions.
  ⑤ Transmission solenoid valve failure:
  The transmission solenoid valve controls the flow of fluid within the transmission. If the solenoid valve is stuck or not working properly, it may disrupt fluid circulation. A diagnostic scan may be needed to identify and resolve solenoid valve problems.
  ⑥ Internal gearbox is damaged:
  Internal damage to transmission components, such as a damaged torque converter or valve body, may impede fluid circulation. This may require a professional inspection and possibly rebuilding or replacing the transmission.
  ⑦ Incorrect transmission oil type:
  Using the wrong type of transmission fluid can cause problems with fluid circulation. Make sure you are using the fluid recommended by the manufacturer for your vehicle.
  ⑧ Coolant contamination:
  If the transmission fluid is contaminated with engine coolant, it may cause poor fluid circulation. This could be caused by a leaking transmission cooler inside the radiator.

  Can recovered refrigerant be reused if it is?

  Yes, recycled refrigerant can be reused if it meets certain conditions and standards. Reuse of recovered refrigerants depends on factors such as refrigerant type, purity and compliance with industry and environmental regulations. The following are key factors that determine whether recycled refrigerant can be reused:
  ① Purity grade:
  Recycled refrigerant must be tested and analyzed to ensure it meets specified purity levels. Different refrigerants have different standards, and recycled refrigerants should meet or exceed these standards before they can be considered for reuse.
  ② Chemical integrity:
  The chemical composition of the recycled refrigerant must remain within acceptable limits to ensure its effectiveness and safety in refrigeration systems.
  ③ Compatibility:
  Recycled refrigerants should be compatible with the specific system type for which they are intended. Mixing different types of refrigerants or using recycled refrigerants in systems that were not specifically designed can cause performance issues and safety issues.
  ④ Regulatory compliance:
  Compliance with environmental regulations and standards is critical for the reuse of recovered refrigerants.
