At Ross Downing Chevrolet in Hammond, LA, we understand the critical role transmission fluid plays in your vehicle’s performance. As your trusted GM experts, we’re here to guide you through the ins and outs of transmission fluid maintenance, helping you keep your Chevrolet running smoothly for years to come.

Understanding Transmission Fluid: Types and Functions
Transmission fluid is the lifeblood of your vehicle’s gearbox, performing several crucial functions:
- Lubrication: It reduces friction between moving parts, preventing wear and tear.
- Cooling: The fluid helps dissipate heat generated during operation.
- Hydraulic Function: It provides the pressure needed for smooth gear shifts.
- Friction Modification: Specially formulated additives ensure optimal clutch operation.
There are two main types of transmission fluid:
- Automatic Transmission Fluid (ATF): Used in automatic transmissions and some manual transmissions.
- Manual Transmission Fluid (MTF): Specifically designed for manual gearboxes.
Both types come in synthetic and conventional formulations, with synthetic offering superior performance and longevity. Some Chevrolet models may require specialty fluids, so it’s essential to consult your owner’s manual or speak with our certified technicians.
The Importance of Regular Transmission Fluid Checks
Regularly checking your transmission fluid is crucial for maintaining your Chevrolet’s performance. Here’s how to do it:
For Automatic Transmissions with a Dipstick:
- Park on level ground and let the engine idle.
- Locate the transmission dipstick (usually near the oil dipstick).
- Remove the dipstick, wipe it clean, reinsert it, and remove it again.
- Check the fluid level and color.
For Manual Transmissions or Vehicles Without a Dipstick:
These often require a professional inspection. Our technicians at Ross Downing Chevrolet can quickly and accurately check your fluid levels.
Interpreting Transmission Fluid Color
The color of your transmission fluid can tell you a lot about its condition:
- Red or Pink: Fresh, clean fluid
- Brown: Slightly worn but still functional
- Dark Brown or Black: Degraded and needs replacement
If you notice metal particles or a burning smell, it’s time for immediate service.
When to Change Your Transmission Fluid
While general guidelines suggest changing transmission fluid every 30,000 to 60,000 miles, the best practice is to follow your Chevrolet’s specific maintenance schedule. Factors like driving habits and conditions can affect fluid longevity.
Many drivers wonder, “Can you just add transmission fluid?” While topping off can help in emergencies, it’s not a long-term solution. Mixing new and old fluid can lead to inconsistent performance.
Signs of Low or Degraded Transmission Fluid
Be alert for these warning signs that indicate your transmission fluid needs attention:
- Slipping gears or delayed shifting
- Unusual noises, especially whining or grinding
- A burning smell coming from under the hood
- Visible leaks on your driveway
- Illuminated warning lights on your dashboard
- Poor acceleration or reduced fuel efficiency
If you experience any of these symptoms, it’s crucial to have your vehicle inspected promptly. Ignoring these signs can lead to costly transmission repairs or even failure.
Transmission Fluid Change vs. Flush: What’s the Difference?
When it’s time for service, you’ll have two options:
- Fluid Change: This involves draining the old fluid and replacing it with new fluid. It’s less expensive but doesn’t remove all the old fluid.
- Fluid Flush: This process uses specialized equipment to remove all old fluid and replace it with new fluid. It’s more thorough but typically costs more.
The choice between a change and a flush depends on your vehicle’s condition and mileage. Our expert technicians can recommend the best option for your Chevrolet.
The Cost of Transmission Fluid Maintenance
While prices can vary, investing in regular transmission fluid maintenance is far more economical than facing major transmission repairs. At Ross Downing Chevrolet, we offer competitive pricing for both fluid changes and flushes, with the exact cost depending on your specific Chevrolet model and the type of fluid required.
