During a routine automatic transmission fluid change, how much fluid is typically not replaced?

During a routine automatic transmission fluid change, how much fluid is typically not replaced?

• A. 1 to 2 quarts (0.9 to 1.9 liters)
• B. 3 to 4 quarts (2.8 to 3.8 liters)
• C. 10 to 15 quarts (9.5 to 14.2 liters)
• D. 5 to 8 quarts (4.7 to 5.7 liters)

Answer: (D)

In a routine automatic transmission fluid change, you drain the pan and replace some fluid, but fluid trapped in the torque converter and within internal passages isn’t removed by a simple pan drop. That remaining fluid means not all of the transmission fluid is replaced during a standard service. The typical amount left in the system after a pan drop is about 5 to 8 quarts (roughly 4.7 to 5.7 liters). This reflects the torque converter’s capacity and the fluid that remains in lines and passages. If you want to replace more of the old fluid, a full flush or additional steps would be needed, but for a standard drain-and-fill, 5–8 quarts is the usual remainder.
