For the 1999 Buick Regal, the manufacturer recommends using Dexron III Automatic Transmission Fluid. This specification is crucial for maintaining the performance and longevity of your transmission. Using the correct type of fluid not only helps in achieving optimal performance but also prevents potential damage that could arise from using an incompatible fluid.
Why Dexron III?
Dexron III is a synthetic blend designed specifically for GM vehicles, including the Buick Regal. Here are a few reasons why sticking to this specification is essential:
- Compatibility: Dexron III is formulated to meet the specific requirements of GM transmissions, ensuring that it provides the right level of friction and lubrication.
- Temperature Stability: This fluid is designed to perform well under a wide range of temperatures, which is crucial for maintaining transmission performance in various driving conditions.
- Wear Protection: Dexron III contains additives that help protect against wear and tear, extending the life of your transmission.
- Foam Resistance: The fluid is engineered to resist foaming, which can lead to erratic shifting and potential damage.
Checking Fluid Quality
While you may not have a dipstick to check your transmission fluid, it’s still important to monitor its condition. Here are some signs that your transmission fluid may need attention:
- Color: Healthy transmission fluid should be a bright red color. If it appears brown or has a burnt smell, it’s time to change it.
- Texture: The fluid should feel smooth and slippery. If it feels gritty or has particles in it, that’s a red flag.
- Performance Issues: If you’re experiencing slipping, hard shifts, or unusual noises, it could be a sign that your transmission fluid is degraded.
Where to Find Reliable Information
For the most accurate and reliable information regarding the transmission fluid type for your Buick Regal, always refer to the owner’s manual. Additionally, reputable automotive websites and forums can provide insights based on real-world experiences from other Buick owners.
Sticking to the manufacturer’s recommendations for transmission fluid is not just a suggestion; it’s a necessity. Using the right fluid ensures that your transmission operates smoothly, prolonging its life and saving you from costly repairs down the line.

Change Interval for Your Buick Regal Transmission Fluid
Maintaining your 1999 Buick Regal’s transmission fluid is crucial for ensuring optimal performance and longevity. Understanding the recommended change intervals and the process of partial oil changes can help you keep your transmission in top shape.
Recommended Change Interval
For the 1999 Buick Regal, the general recommendation for changing the transmission fluid is every 30,000 to 60,000 miles (approximately 48,000 to 96,000 kilometers). However, this interval can vary based on driving conditions and habits. Here’s a breakdown:
- Normal Driving Conditions: If you primarily drive in moderate conditions—such as highway driving with minimal stop-and-go traffic—aim for the 60,000-mile mark.
- Severe Driving Conditions: If you often drive in heavy traffic, tow heavy loads, or frequently drive in extreme temperatures, consider changing the fluid closer to the 30,000-mile mark.
Statistical data from automotive maintenance studies indicate that regular fluid changes can significantly reduce the risk of transmission failure. According to the Automatic Transmission Service Group (ATSG), neglecting to change the transmission fluid can lead to increased wear and tear, ultimately resulting in costly repairs.
Partial Transmission Oil Changes
In many cases, a complete transmission fluid change requires removing the transmission from the vehicle, which can be a labor-intensive and costly process. This is where partial transmission oil changes come into play.
What is a Partial Oil Change?
A partial oil change involves draining a portion of the old transmission fluid and replacing it with new fluid. This method can be beneficial for several reasons:
- Cost-Effective: Partial changes are generally less expensive than full fluid changes, making them more accessible for regular maintenance.
- Less Labor-Intensive: Since a full transmission removal is not required, partial changes can be performed more quickly, reducing labor costs.
- Improved Fluid Quality: Over time, transmission fluid can become contaminated with debris and wear particles. A partial change helps to dilute these contaminants, improving overall fluid quality.
Justification for Partial Changes
Research shows that even partial fluid changes can have a positive impact on transmission health. According to a study published by the Society of Automotive Engineers (SAE), regular partial fluid changes can help maintain the viscosity and performance characteristics of the transmission fluid, thereby extending the life of the transmission.
- Fluid Contamination: Studies indicate that contaminants in transmission fluid can lead to increased wear on internal components. Regular partial changes help to mitigate this issue.
- Heat Management: Fresh fluid has better heat-dissipating properties. By regularly replacing a portion of the fluid, you can help manage the heat generated during operation, which is crucial for transmission longevity.
- Cost Savings: By performing partial changes at regular intervals, you can avoid the high costs associated with complete transmission overhauls or replacements.
In summary, adhering to the recommended change intervals for your Buick Regal’s transmission fluid and considering partial oil changes can significantly enhance your vehicle’s performance and longevity. Regular maintenance is key to preventing costly repairs down the road.
