What are the steps for changing the oil in an automatic transmission using a machine?

[McGrant]

Here are the steps for changing the oil in an automatic transmission: 1. Connect the exchange machine: Open the hood, place fender pads, lift the vehicle, perform a simple inspection of the vehicle's chassis, locate and confirm the position of the transmission cooling oil pipes, select the appropriate connecting adapters, and connect the two hoses of the exchange machine to the transmission's inlet and return oil pipes respectively. 2. Check the old oil: Start the vehicle, connect the smart exchange machine to the battery, turn on the smart exchange machine, and observe the cleanliness of the old oil from the old oil display tube. If metal particles, sludge, friction plate fragments, or other impurities are found in the old oil, it may indicate internal wear in the transmission, requiring further repairs and making it unsuitable for an oil change at this time. 3. Replace the filter: Turn off the engine, lift the vehicle, open the drain plug, and drain the old oil. Use a measurable container to collect the old oil, remove the oil pan, and pour the oil inside the oil pan into the old oil container. Replace the oil pan gasket and, if possible, also replace the filter. Note that the location of the filter may vary significantly between different vehicles. 4. Circulation cleaning: Add new oil to the exchange machine, activate the "fill new oil" function of the exchange machine, set the filling amount to match the drained old oil quantity, and start the vehicle. Activate the "circulation cleaning" function of the exchange machine. The driver should operate the gearshift mechanism to perform circulation cleaning for each gear, with each gear's cleaning time controlled within 5-10 seconds, and the total circulation time between 5-8 minutes. 5. Equal exchange: After circulation, stop the engine, add new oil to the exchange machine again, and select the "equal oil exchange" function. Upon completion, observe whether the colors of the new and old oil in the exchange machine match. If they match, the operation is complete. If not, continue adding new oil until the colors of the new and old oil match. Check if the oil level is sufficient. For transmissions with a dipstick, check the dipstick's scale position. For those without a dipstick, lift the vehicle and open the inspection bolt. Excess oil will overflow from the inspection bolt hole. If no overflow occurs, add new oil via the smart exchange machine based on the actual situation until oil overflows.
