What are the steps for a transmission fluid flush?

[Emil]

Steps for transmission fluid flush: 1. Locate the transmission fluid filler port and drain port, then connect the inlet and outlet hoses of the flushing machine. 2. Fill the flushing machine with automatic transmission fluid. 3. Start the machine to begin the automatic flushing process, during which the vehicle needs to be running. 4. When the fluid in the old oil viewing window becomes clear, it indicates the old transmission fluid has been completely replaced. Below are the hazards of not changing automatic transmission fluid for an extended period: 1. Failure to change transmission fluid may cause abnormal wear and severe fluid degradation in the transmission. 2. Unchanged transmission fluid working under high-speed and high-temperature conditions will degrade and evaporate, accelerating mechanical component wear and potentially damaging internal transmission parts, shortening the vehicle's lifespan. 3. Prolonged use of unchanged transmission fluid can cause fluid particulation, blocking oil passages and damaging valve bodies, directly affecting system oil pressure and power transmission, resulting in delayed response and gear shift shock.
