Cadillac DeVille Transmission Fluid Capacity

The Cadillac DeVille is a classic line of full-size luxury sedans from one of America’s most storied automakers, Cadillac. Renowned for its opulence, performance, and innovative features, the DeVille was a staple in the Cadillac lineup for over five decades. With its grandeur and roomy interiors, the DeVille was a symbol of comfort and prestige, making it a favorite among luxury car enthusiasts.

Seventh Generation (1994–1999)

Introduced in 1994, the seventh-generation Cadillac DeVille carried forward the brand’s dedication to luxury and performance. These models showcased a new design with more rounded lines and modern aesthetics, moving away from the boxy designs of the ’80s. Under the hood, the DeVille featured a 4.6L Northstar V8 engine coupled with a 4-speed automatic transmission.

This generation also marked the introduction of the Northstar System, which included the Northstar engine and other advanced features like road-sensing suspension, variable power steering, and traction control. This system was a significant leap forward for Cadillac in terms of technology and performance.

Eighth Generation (2000–2005)

The eighth and final generation of the Cadillac DeVille, released in 2000, was a further evolution of the model in terms of design, comfort, and technology. This generation featured a more streamlined and modern design, improved interior space, and advanced safety features, including side-impact airbags.

Powering the DeVille was the same 4.6L Northstar V8 engine, but it came in two variations, LD8 and L37, producing different power outputs. The engine was again paired with a 4-speed automatic transmission. One of the standout features of this generation was the inclusion of night vision, a first in a production vehicle.

Cadillac DeVille Transmission Fluid Type & Capacity

ACDelco GM Original Equipment 10-9395 Dexron VI Automatic Transmission Fluid – 1 gal
  • Backward compatible with previous Dexron automatic transmission fluids and can be used as a much-improved replacement for older vehicles/transmissions originally using previous Dexron fluids
  • Improved performance over previous Dexron fluids in: friction durability, viscosity stability, aeration and foam control, and oxidation resistance
  • Potential to enable improved fuel economy and longer transmission life
  • Provides for extended drain intervals. Provides consistent shift performance, even in extreme conditions.

Seventh Generation DeVille (1994–1999)

For the seventh generation of the Cadillac DeVille, the automaker recommends using Dexron-VI automatic transmission fluid. This fluid type is designed to meet the lubrication needs of the car’s 4-speed automatic transmission, ensuring optimal performance and longevity.

When it comes to fluid capacity, it varies depending on the specific service being performed. For a routine change where the transmission fluid is drained and refilled, it usually requires approximately 7.4 quarts (7 liters) of transmission fluid. However, when the system is completely dry, such as in a rebuild scenario, it might need around 15 quarts (14.2 liters) of fluid.

Eighth Generation DeVille (2000–2005)

The eighth-generation DeVille continued to use the Dexron-VI transmission fluid. It’s important to note that using the right fluid type is essential for keeping your transmission running smoothly and prolonging its lifespan.

The fluid capacity for the eighth-generation DeVille is similar to the seventh-generation. A standard drain and refill usually need approximately 7.4 quarts (7 liters) of fluid. Meanwhile, a completely dry system would require around 15 quarts (14.2 liters) of transmission fluid.

Always remember to consult your vehicle’s owner’s manual or a professional mechanic to get accurate information for your specific model and year. Properly maintaining the transmission fluid can ensure a smoother ride and prolong the life of your Cadillac DeVille’s transmission.

Importance of Regular Transmission Fluid Change

The importance of regular transmission fluid changes in any vehicle, including the Cadillac DeVille, cannot be overstated. The transmission fluid serves multiple essential roles in your vehicle:

  1. Lubricant: It lubricates all the moving parts in the transmission, reducing friction, preventing overheating, and minimizing wear and tear.
  2. Coolant: It helps to cool the transmission by carrying heat away, preventing overheating that could lead to damaging the system.
  3. Pressure: The fluid is used to create hydraulic pressure, which is necessary for the shifting of gears in an automatic transmission.

With time and usage, the fluid can degrade and get contaminated with small particles of metal from the transmission. If not replaced, the degraded fluid can lead to accelerated wear and tear on the transmission, resulting in decreased performance, gear slipping, overheating, and eventual transmission failure. Therefore, changing the transmission fluid at regular intervals is crucial to maintaining the performance, efficiency, and longevity of the transmission system.

Notably, the importance of a regular transmission fluid change extends beyond the transmission itself. It contributes to the overall health of your vehicle, enhancing performance, promoting fuel efficiency, and preventing potentially costly repairs down the line. It’s a relatively small maintenance investment that can pay off significantly in the long run.

The recommended frequency for changing transmission fluid can vary depending on the specific model, driving conditions, and the type of fluid used. As a general rule of thumb, many automakers, including Cadillac, suggest changing the transmission fluid approximately every 30,000 to 60,000 miles.

However, if your Cadillac DeVille is often driven under more severe conditions – such as in heavy city traffic, on mountainous or hilly terrain, or when towing – it’s advisable to change the fluid more frequently, potentially every 15,000 to 30,000 miles.

It’s also important to regularly check the condition of the transmission fluid. If the fluid is a dark brown color or has a burnt smell, it’s time for a change. Small particles of dirt or metal in the fluid are also signs that a change is needed.

Always refer to your Cadillac DeVille’s owner’s manual for the most accurate information. This guide will provide you with specific recommendations for your vehicle model and year. Consulting a professional mechanic or your local Cadillac dealership can provide additional insights based on your driving habits and the specific conditions in your area.

Costs Associated with Changing Transmission Fluid

The cost to change the transmission fluid in your Cadillac DeVille can vary based on several factors such as your geographic location, whether the service is performed at a dealership or an independent shop, and the exact procedures included in the service. On average, you can expect to pay between $100 and $200 for a transmission fluid change. This price typically includes labor and the cost of the fluid itself.

While this is a routine maintenance expense, it’s important to remember that regular transmission fluid changes can help prevent more serious and expensive transmission issues down the line. In this sense, the cost of fluid changes can be seen as an investment in the long-term performance and reliability of your vehicle.

Tips for Maintaining Your Cadillac DeVille Transmission

  1. Regularly Check Your Fluid: Make it a habit to check your transmission fluid regularly. The fluid should be clear and reddish. If it’s brown or has a burnt smell, it’s time for a change.
  2. Use the Right Fluid: Always use Dexron-III fluid for your seventh and eighth-generation Cadillac DeVille. Using the wrong fluid can cause damage to your transmission.
  3. Warm Up Your Car: Especially in colder weather, let your car run for a few minutes before driving. This helps the transmission fluid circulate and function optimally.
  4. Avoid Aggressive Driving: Rapid acceleration and heavy braking can put stress on your transmission. Drive smoothly to help prolong the life of your transmission.
  5. Regular Maintenance: Beyond fluid changes, regular servicing of your car can help catch potential issues early before they become more serious (and expensive) problems.


The Cadillac DeVille is a model that represents luxury and performance. Maintaining its transmission fluid at the right levels and changing it at the recommended intervals is crucial to keeping your DeVille running smoothly and reliably.

With regular checks and upkeep, your DeVille can deliver the performance and comfort it was designed for, ensuring you enjoy every drive. Remember, always refer to your owner’s manual or consult a professional for specifics related to your model and year.
