How many quarts of transmission fluid does a 4R70W take?
The Ford 4R70W automatic transmission typically requires about 11 quarts of ATF for a complete refill, including the torque converter contents. The exact amount you drain and refill depends on the service method you choose, such as a pan drop with filter change or a full fluid flush.
Understanding capacity by service method
What follows explains the typical fluid quantities you can expect for common 4R70W service scenarios.
Below are typical fluid quantities you can expect for common 4R70W service scenarios.
- Full capacity (including torque converter contents): about 11 quarts
- Pan drop with new filter: typically 7–9 quarts drained/replaced
- Complete flush or converter drain: around 11–12 quarts to bring the system to spec
- Note: actual amounts vary by model year, vehicle configuration, and whether the torque converter is drained during service
Bottom line: plan on roughly 11 quarts for a full refill. If you’re performing only a pan drop with filter replacement, you’ll usually replace about 7–9 quarts, then top off to the correct level once the transmission reaches operating temperature and the level is checked with the dipstick.
Summary
The 4R70W’s total transmission fluid capacity is generally around 11 quarts for a complete refill, with practical service amounts ranging from about 7–9 quarts for a pan drop with filter change to 11–12 quarts for a thorough flush. Always verify with the vehicle’s service manual and use the dipstick to confirm correct level after warming the transmission.
