How many quarts of transmission fluid does a 2007 Lexus IS250 take?

For a 2007 Lexus IS 250 with the factory 6-speed automatic, you should plan for roughly 9 quarts of ATF for a full system fill. A simple pan drain-and-fill typically replaces about 3–4 quarts, while a complete service that involves pan removal and filter change can bring the total closer to 9–10 quarts. Always confirm the exact specification for your VIN in the owner's manual or with a Lexus dealer.

Total capacity and typical service volumes

Understanding the main quantities helps you budget fluids and plan service steps.

• Total transmission fluid capacity (including the torque converter) is typically about 9 quarts.


• A pan-only drain-and-fill usually replaces about 3–4 quarts of ATF.


• A full system replacement, including pan, filter, and gasket if applicable, may require about 9–10 quarts depending on the exact procedure and whether any additional drainage is performed.

In practice, the exact amounts depend on whether you’re performing only a pan drain and refill or a full service that includes the pan, filter, and gasket. Always verify the current service procedure for your vehicle and recheck the level after warming up the car and cycling through gears.

ATF type and service notes

Choosing the correct ATF specification is essential for transmission longevity and smooth shifting. For the 2007 IS 250, Lexus typically specifies Toyota/Lexus World Standard (ATF WS) or Dexron VI compatibility, depending on production revision and transmission hardware. Always consult the owner’s manual, the under-hood label, or a Lexus dealer with your VIN to confirm the exact specification and any revision notes.

• Use the ATF specified for your vehicle (often WS or Dexron VI compatibility); never mix old and new ATF outside the proper procedure.


• Check the level with the vehicle at operating temperature and ensure the fluid is within the correct range on the dipstick or fill plug, if equipped.


• Perform a full service with a new filter (if accessible) and pan gasket during a complete drain and fill for best reliability.

In short, follow the exact specification for your vehicle and keep records of the ATF type used for future maintenance.

Do-it-yourself steps and cautions

Readers considering a DIY approach should know that some IS 250 models have non-serviceable filters or require special equipment for a full system drain. If you’re unsure, it’s wise to have a professional handle the service.

Service levels and best practices

Before you begin, determine whether you’re doing a pan drain-and-fill or a full replacement and gather the correct fluids and parts.

• Warm up the vehicle to operating temperature to ensure ATF is evenly circulated and flows more freely when drained.


• Raise and support the car securely; position a drain pan beneath the transmission pan.


• Remove the pan bolts, allow ATF to drain fully, then replace the pan gasket and filter if accessible.


• Install the pan, begin with a conservative amount of ATF (about 4 quarts to start if doing a full replacement), then start the engine and shift through the gears to circulate fluid.


• With the engine running and the transmission at operating temperature, check the level and top off to the correct mark; recheck after a short drive.

A careful approach that follows the manufacturer’s specifications and a service manual reduces the risk of overfilling or underfilling the transmission.

Summary

For a 2007 Lexus IS 250 with a 6-speed automatic, expect about 9 quarts of ATF for a full system fill. A pan drain-and-fill typically replaces around 3–4 quarts, while a complete service with a new filter can bring the total closer to 9–10 quarts. Always verify the exact ATF specification for your VIN and follow the recommended service procedures. When in doubt, consult a qualified technician.

How much is a transmission fluid change for a 2007 Lexus IS250?

The average cost for a Lexus IS250 Transmission Fluid Change is between $222 and $285. Labor costs are estimated between $134 and $197 while parts are typically priced around $88.

How much transmission fluid does a Lexus IS250 take?

The Lexus IS250 automatic transmission fluid capacity for a drain and refill is about 2 quarts for 2WD and 3 quarts for AWD. The total capacity is around 7.6 to 9.4 quarts depending on the model (2WD or 4WD), but a drain and refill will not replace the total amount of fluid in the transmission. The manual transmission has a capacity of 1.8 quarts. 
Automatic Transmission (A960E)

• Drain and refill (2WD): ~2 quarts
• Drain and refill (AWD): ~3 quarts
• Total capacity (2WD): ~7.5 to 7.6 quarts
• Total capacity (AWD): ~9.4 quarts 

Manual Transmission

• Drain and refill: 1.8 quarts (1.7 L)

Important notes

• Always use the correct fluid type, which is Toyota Genuine ATF WS for the automatic transmission and SAE 75W-90 (API GL-4 or GL-5) for the manual transmission. 
• A drain and refill will only replace a portion of the old fluid. Multiple drain and refill cycles are recommended to replace a higher percentage of the old fluid. 
• For an automatic transmission, it's best to fill the new fluid to the overflow plug after reaching the correct operating temperature to ensure the proper level.

How many quarts of transmission fluid do I need for a drain and fill?

For a standard transmission fluid drain and fill, you'll typically need 3 to 5 quarts, but you should always measure the amount you drained and refill with the same amount to start, then check the level using the dipstick after running the engine. The exact amount varies by vehicle, and it's crucial to check the owner's manual or look up specifications for your specific make and model, as a drain and fill will not replace all the old fluid. 
How to determine the right amount

• Drain the old fluid: Let the old fluid drain completely. 
• Measure the drained fluid: Measure how much fluid was drained. This is your starting point for refilling. 
• Refill with the measured amount: Put the same amount of new, correct transmission fluid back into the transmission. Using a funnel can help with this process. 
• Start the engine: Start the vehicle and let it run for a few minutes, shifting through all the gears (Park, Reverse, Neutral, Drive) while holding the brake. This circulates the new fluid. 
• Check the level: Turn the engine off and check the fluid level with the dipstick. Add more fluid in small increments if the level is low, or drain a small amount if it's too high. 
• Re-check: Repeat the process of running the engine and checking the dipstick until the fluid level is correct according to the dipstick's hash marks for a "hot" reading. 

Important considerations

• A drain and fill is different from a full transmission flush, which requires significantly more fluid (10-12 quarts or more) because it aims to replace all the fluid, including what's in the torque converter. 
• You should always use the specific type of transmission fluid recommended by your vehicle's manufacturer to avoid damage. 
• Some vehicles, like certain Land Rovers, do not have a dipstick and require a fluid extractor to add new fluid. Consult your owner's manual to be certain. 

What kind of transmission fluid does a 2007 Lexus IS250 take?
