Is a Transmission Fluid Flush Necessary?
1 Answers
Transmission fluid flush requirements depend on the situation. 1. Manual transmissions have lower demands on transmission fluid due to their simpler structure. Manual replacement is generally sufficient and more economical. 2. For automatic transmissions, a flush is recommended. Automatic transmissions have more complex structures and higher fluid requirements. Poor-quality fluid can easily cause issues. A transmission fluid flush ensures complete replacement, offering more thorough results and extending the maintenance interval. The specific steps for a transmission fluid flush using a machine are as follows: 1. Locate the transmission fluid fill and drain ports, then connect the machine's inlet and outlet hoses. 2. Fill the machine with automatic transmission fluid. 3. Start the machine and initiate the automatic replacement process, which requires starting the vehicle during the procedure. 4. When the old fluid in the viewing window appears clear, it indicates the old fluid has been fully removed, and the replacement is complete. 5. Typically, a machine-assisted flush uses over twice the amount of new fluid compared to manual replacement, requiring 9-12 liters of new fluid. Although the cost is higher, the results are significantly better, making it ideal for automatic transmissions.
