How often should I replace the transmission fluid on my Acura?

For most Acura models with traditional automatic transmissions, a transmission fluid change is commonly recommended around 60,000 miles under normal driving. If you drive a model with a CVT, the interval can differ and may be longer or shorter depending on conditions; always consult the owner's manual or your dealer's maintenance minder to confirm.

This article explains the factors that influence interval, how to know which interval applies to your vehicle, and what to expect during service.

Know your transmission type and official intervals

Use these guidelines to estimate when your Acura's transmission fluid should be changed. Note that exact intervals depend on year, model, and whether you have a traditional automatic or a CVT.

• Traditional automatic transmissions (most older Acura models): About 60,000 miles under normal driving; more frequent changes—roughly every 30,000–40,000 miles—if you regularly tow, drive in severe heat, or endure heavy stop-and-go traffic or mountainous terrain.


• CVT transmissions (used in several Acura models): Typically around 60,000 miles under normal conditions; many models use Acura's maintenance minder to adjust the interval, and more frequent changes may be advised under severe driving or harsh climates.


• Both types: Always consult your owner’s manual or dealer for model-specific intervals, as some years or trims may have different recommendations, and warranty coverage can depend on following the schedule.

Maintenance minder and dealer recommendations should guide you if your vehicle is newer or carries a specific warranty. If in doubt, ask your service advisor to pull up the exact interval for your VIN.

Signs that your transmission fluid may need replacement

Even if you’re within the published interval, signs that your transmission fluid needs changing can arise, and detecting them early can prevent more serious problems.

• Slipping or hard shifting between gears


• Unusual or burning smells coming from the transmission area


• Fluid that appears dark brown or has a burnt odor, or is gritty/abrasive


• Transmission warning light or shifting hesitations


• Overheating or external leaks showing low fluid level

When you notice any of these signs, schedule a service appointment promptly. A fluid change, if performed correctly with the right spec and amount, can restore smooth operation and protect the transmission.

What to expect during service

There are two common approaches to changing transmission fluid: drain-and-fill and, less commonly, a professional fluid flush. Acura manuals typically advise using the exact spec of ATF or CVT fluid and ensuring the correct amount is added. Some transmissions in modern cars are filled to a precise level, and professionals will verify level while the engine is running. If your vehicle is under warranty or you have driven in severe conditions, your technician may recommend a fluid change more often.

Before any service, confirm whether the shop will use OEM-spec fluid and whether they recommend drain-and-fill only versus a full flush. For CVTs, using the correct CVT fluid is crucial to performance and longevity.

Summary

In general, plan for a transmission fluid change around 60,000 miles for most Acura automatics, and 60,000 miles for many CVTs as well, with adjustments for severe driving. Always verify the exact interval in your owner's manual or via Acura's maintenance minder for your model year and trim, and monitor for signs of wear. Routine checks and using the correct fluid type are essential to prolonging transmission life.

Is Acura reliable after 100K miles?

Yes, Acuras are generally very reliable after 100k miles, especially with consistent maintenance, as they are built with quality engineering from their Honda roots. Key to this reliability is following the recommended maintenance schedule, which includes performing major services like transmission fluid changes and, for models with a timing belt, replacing it around the 100k mark. 
Key factors for long-term reliability

• Follow the maintenance schedule: Regular oil changes, fluid replacements, and other services are crucial for longevity. 
• Pay attention to major service intervals: At around 100,000 miles, certain components, like the timing belt in older models, need to be replaced. 
• Transmission fluid is critical: Changing the transmission fluid at recommended intervals is one of the most important aspects of keeping the car running smoothly long-term. 
• Consider the engine: While many Acura engines are very reliable, some J-series engines have a history of oil consumption issues, especially older ones. 
• Potential for issues: As with any car, some issues can arise after 100k miles, such as air conditioning system problems or oil consumption, so it's wise to factor in potential repair costs. 

What drivers say

• Many owners report driving their Acuras for hundreds of thousands of miles with minimal issues if proper maintenance was performed.
• Owners of older models like the TL and MDX often report that the engines remained in good condition even after the transmission began to show wear. 

Does Honda recommend transmission flush or drain and fill?

DW1. You will need to do this up to three times to remove all of the old transmission fluid to get it back to that nice new pink color and all new fluid draining will only remove almost four quarts.

How often should Acura transmission fluid be changed?

Acura recommends changing transmission fluid based on driving conditions and model year, typically between every 30,000 and 60,000 miles for most models. For severe driving, such as frequent stop-and-go traffic or towing, the interval may be shorter, around 30,000 to 40,000 miles. It's best to check your owner's manual for the specific recommendation for your vehicle, or follow the Acura Maintenance Minder system, which can trigger a service alert around 45,000 to 50,000 miles.

Factors that influence the interval

• Driving conditions: A "severe" driving schedule (stop-and-go traffic, towing, hot weather) requires more frequent changes, potentially as often as every 30,000 miles. 
• Vehicle model: Different models have different needs. For example, a 2019 TLX with a 9-speed automatic may be recommended at 60,000 miles under normal conditions, while some models may require service at 30,000-mile intervals. 
• Maintenance Minder: The on-board maintenance system will provide a service reminder when it's time to have the transmission fluid changed. This can appear around 45,000 to 50,000 miles, depending on driving habits. 
• Manual vs. automatic: Manual transmissions generally have a shorter change interval than automatic ones. For a manual transmission, a change is recommended between 30,000 and 60,000 miles.

How much does Acura charge for transmission fluid change?

The cost to change the transmission fluid in an Acura ranges from approximately $150 to over $450, depending on the shop type, model, and location. Dealerships typically charge more, from around $280 to over $450, due to specialized training and OEM parts. Independent shops may charge between $150 and $350. 
Factors that influence cost

• Shop Type: Dealerships often have higher labor rates and use manufacturer-approved parts, which can increase the price. 
• Vehicle Model: Some modern Acura transmissions, like the ZF9 in certain TLX models, have a more complex procedure and use expensive, specialized fluid and single-use parts, raising the cost. 
• Service Scope: A basic drain and fill will be cheaper than a full flush or a service that includes additional components like the transfer case fluid (common on AWD models) or a new filter and gasket. 
• Fluid Cost: The specific type of automatic transmission fluid (ATF) required for your Acura can be costly, especially if it's a specialized OEM fluid. 

Where to find the best price

• Get multiple quotes: Contact both the dealership and independent repair shops to compare prices for your specific vehicle model.
• Ask about included services: Confirm what is included in the price. Some quotes may not include the transfer case fluid, and some services may not include replacing the filter or gasket. 
• Consider the DIY option: If you are mechanically inclined, doing it yourself can significantly lower the cost, though you will need to purchase the necessary tools and fluids.
