Benefits of a Properly Working Transmission
Your car’s transmission is what allows you to shift gears and transfer power from the engine to the wheels efficiently. When it’s working correctly, you’ll enjoy:
- Smooth acceleration and deceleration
- Better fuel economy
- Reduced wear on your vehicle’s transmission
- Improved transmission life
- Greater control in both manual and automatic driving modes
By following a proper maintenance schedule—including routine transmission fluid flushes and transmission maintenance—you can avoid breakdowns and prevent major repair expenses down the road.
What Does Transmission Trouble Look Like?
Whether your vehicle is equipped with a modern automatic transmission or a manual transmission, trouble can present itself in a variety of ways. Be on the lookout for these red flags:
- Rough or delayed engagement during gear shifts
- A burning smell or leaking transmission fluid
- Strange noises like grinding, whining, or clunking
- The car’s engine revving without movement
- Difficulty getting into gear
- Dashboard warning lights
If you notice any of these issues, it may signal a malfunctioning transmission—and it’s time to schedule a transmission service at our St. Louis shop.
Transmission Fluid FAQs
1. How often should I change transmission fluid?
For most vehicles, it’s recommended to change the transmission fluid every 30,000 to 60,000 miles, but this can vary based on your vehicle’s transmission type, driving habits, and manufacturer guidelines. Always refer to your owner’s manual or consult our technicians for a maintenance schedule tailored to your car.
2. What are the signs that my transmission fluid needs to be changed?
Common signs include delayed or rough shifting, a burning smell, slipping gears, or discolored or dirty transmission fluid. If you notice any of these issues, it’s best to have your transmission fluid checked as soon as possible to prevent damage.
3. Can I check my transmission fluid myself?
In many vehicles, yes. Some have a transmission dipstick under the hood, similar to the engine oil dipstick. With the engine warmed up and running, you can check the fluid level and condition. However, most modern automatic transmissions are sealed and require a professional to check. When in doubt, bring your car in and we’ll inspect it for you.
