How many kilometers does the Buick New Regal need to change the transmission oil?

[LeEverly]

The New Regal requires a transmission oil change every three years or 60,000 kilometers. Failure to replace the transmission oil in time may easily lead to transmission damage. Using a circulation machine to change the transmission oil can more thoroughly replace the residual oil in the solenoid valve and torque converter. More details are as follows: 1. Transmission oil plays the roles of transmission, lubrication, cooling, and cleaning in the transmission. There are three methods to change the transmission oil. The first is gravity oil change, which is simple but may leave waste oil inside due to gravity drainage. 2. The second is circulation oil drainage. Although this method takes longer, it results in a cleaner oil change. The third is removing the transmission oil pan for an oil change, but this method involves complete disassembly and is cumbersome and complicated. 3. Currently, the better method for oil change is circulation drainage, which uses specialized transmission cleaning equipment. During the operation of the transmission, the old oil is fully circulated and thoroughly drained before adding new transmission oil, achieving an oil change rate of over 90% and ensuring a good oil change effect.
