When should I change the transmission fluid in my Acura?

In most Acura models, you should plan a transmission fluid change around 60,000 miles under normal driving. You may need it sooner if you regularly tow, drive in hot climates, or endure a lot of stop-and-go traffic. Always verify the exact interval in your vehicle’s owner's manual or with a trusted Acura dealer for your model and year.

Transmission fluid servicing is not one-size-fits-all. The type of transmission (conventional automatic vs. CVT) and the operating conditions will influence the recommended interval. This guide outlines current guidance for 2025 and provides practical steps to determine the right schedule for your Acura.

Know your transmission type

Acura uses different transmission technologies across its lineup, and the service interval for fluid changes varies by whether you have a conventional automatic or a continuously variable transmission (CVT). Start with your owner's manual or a dealer service bulletin to confirm the exact schedule for your model/year.

Conventional automatic transmissions

The majority of Acura models with a traditional automatic transmission follow a baseline change interval around 60,000 miles under normal driving. Under severe conditions, you may be advised to service more frequently.

Below is a general overview of how the scheduling typically breaks down. Read this as a baseline guide, not a substitute for your manual.

• Normal driving: Change transmission fluid around 60,000 miles (97,000 km).


• Severe driving: Change around 30,000 miles (48,000 km) or sooner if you meet criteria such as frequent towing, hot climate, heavy traffic, or dusty conditions.


• Fluid type: Use the ATF recommended for your model—many Acura models specify a DW-1 or equivalent Honda/Acura ATF unless otherwise directed.


• Service approach: Some dealers offer a drain-and-fill rather than a full flush; discuss the pros/cons with your technician.

Bottom line: For conventional automatics, the typical target is around 60,000 miles under normal conditions, with earlier service under tougher usage. Always confirm with the manual or dealer guidance for your exact vehicle.

CVT-equipped models

For Acura models that use a continuously variable transmission, the fluid is a dedicated CVT fluid rather than standard automatic transmission fluid. The replacement interval is often similar to the conventional automatic baseline, but your manual will specify the exact requirements for your vehicle. If you drive under severe conditions, plan for more frequent changes as advised by Acura.

Common guidance (model-year dependent) includes the following framework. Treat these as general references and verify for your car.

• Normal driving: CVT fluid change around 60,000 miles (97,000 km).


• Severe driving: CVT fluid change around 30,000 miles (48,000 km) or sooner with towing, hot climates, or heavy stop-and-go usage.


• Fluid specification: Use the CVT fluid specified by Acura for your model/year; do not mix fluids or use generic alternatives unless explicitly approved.

Conclusion: CVT maintenance hinges on the exact model and year, so always check the owner’s manual or ask an Acura technician for your specific interval and fluid specification.

Signs your transmission fluid may need changing

Even if you’re not at the scheduled interval, pay attention to symptoms that suggest a fluid change could be overdue or required sooner. Early action can prevent more expensive problems.

• Burnt or unusual smell coming from under the hood or transmission area.


• Fluid that’s dark brown or has a gritty or burnt appearance.


• Slipping, hard shifts, or delayed engagement when selecting drive or reverse.


• Grinding noises, especially during changes in gear or at idle.


• Low transmission fluid level or visible leaks beneath the vehicle.

Bottom line: If you notice any of these signs, have your transmission fluid inspected by a qualified technician and avoid delaying service to protect the transmission.

How to change transmission fluid properly

Deciding between a DIY drain-and-fill versus a professional flush depends on your comfort level, the model, and the service history. Acura vehicles often require specialized procedures and the correct fluid. Use this as a practical guide to understand the steps involved and what to discuss with your shop.

1. Confirm the correct fluid type for your model/year (ATF for conventional automatics or CVT fluid for CVT-equipped models).


2. Prepare the vehicle: use a level surface, engage the parking brake, and raise the vehicle if needed for access.


3. Drain the old fluid: a drain-and-fill will remove a portion of the fluid; a professional flush may replace more of the old fluid but can be more invasive.


4. Replace the transmission filter (if applicable) and reset or reprogram any transmission adaptation memory as required by your model.


5. Refill with the correct amount and type of fluid, then check the level with the transmission at operating temperature as specified in your manual.


6. Road-test the car to ensure smooth shifting and verify there are no leaks after the service.


7. Dispose of used fluid according to local environmental regulations and use a reputable service provider or dealer for the disposal.

Conclusion: Properly changing transmission fluid is a straightforward maintenance task when you follow the right fluid specification and procedure for your model. When in doubt, rely on a certified Acura technician to perform or supervise the service.

Summary

Transmission fluid maintenance for Acuras depends on transmission type and driving conditions. Conventional automatics generally target about 60,000 miles under normal conditions, with earlier changes under severe usage. CVT-equipped models follow a similar framework but rely on CVT-fluid specifications. Always consult your owner’s manual or an Acura dealer for model-year specifics, watch for warning signs that fluid is degraded, and choose the appropriate service method (drain-and-fill vs. flush) based on your vehicle’s needs. Regular monitoring and timely service help protect your transmission and keep your Acura performing at its best.

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. 

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.
