Steps for using an automatic transmission fluid exchanger: 1. Locate the vehicle's external exchanger connection port; 2. Identify the inlet and outlet hoses of the connection port; 3. Connect the exchanger's hoses to the machine and fill the container with automatic transmission fluid. Functions of the transmission: 1. Alter gear ratios to meet varying traction requirements under different driving conditions; 2. Enable reverse driving; 3. Interrupt power transmission to the drive wheels during engine startup, idling, gear shifting, or when stopping power output. Methods for troubleshooting automatic transmission issues: 1. Perform computer diagnostics and replace faulty electronic components; 2. Repair damaged mechanical components; 3. Inspect the engine and ABS system, repairing any defective parts; 4. Systematically analyze potential causes including high engine coolant temperature, transmission clutch slippage, insufficient cooling, or blocked vehicle cooling grilles. Functions of the transmission: 1. Change gear ratios to accommodate different traction needs; 2. Allow reverse movement; 3. Disengage power transmission to drive wheels during engine start, idle, gear changes, or when stopping power output.
The steps for using an automatic transmission flush machine to change the oil, which I have personally performed several times, are shared here for everyone. First, park the car on a level surface and start the engine to warm it up for a few minutes, allowing the transmission fluid to reach a moderate temperature for better circulation. Then, locate the cooling line connections of the transmission, usually near the radiator, disconnect the original lines, and connect the inlet and outlet hoses of the flush machine, ensuring the connections are secure and leak-free. Next, start the flush machine, set the appropriate flow rate, and simultaneously extract the old fluid while pumping in the new fluid, keeping an eye on the color change in the fluid reservoir until the new fluid appears clear and uncontaminated. This process takes about 10-15 minutes—don’t rush to turn off the engine. Once completed, carefully disconnect the hoses, reattach the original lines, and check whether the transmission fluid level is within the normal range, topping up or adjusting as needed. Finally, turn off the engine and test the gear shifts for smoothness. Performing this maintenance regularly can extend the transmission’s lifespan, but remember to use professional equipment and the correct fluid—DIY attempts can easily go wrong, so beginners are advised to seek guidance from a professional first.
