If you’re heading in for a regular oil change, you might wonder: Does an oil change include transmission fluid? The quick answer is: No — an oil change and a transmission fluid change are two separate services. However, some shops may check your transmission fluid level during a routine oil change.
What’s the Difference Between Engine Oil and Transmission Fluid?
| Engine Oil | Transmission Fluid |
|---|---|
| Lubricates engine components | Lubricates and powers transmission |
| Needs changing every 3,000–7,500 miles | Needs changing every 30,000–60,000+ miles |
| Comes in different viscosity grades | Varies by vehicle (manual vs. automatic) |
| Changed during oil service | Changed during a transmission service |
These fluids serve completely different systems in your vehicle.
What’s Included in a Standard Oil Change?
A basic oil change service typically includes:
- Draining old engine oil
- Replacing the oil filter
- Adding new engine oil
- Lubricating the chassis (if applicable)
- Performing a multi-point inspection
During that inspection, some service centers may check the transmission fluid level and condition — but they won’t replace or flush it unless you request a separate service.
When Should Transmission Fluid Be Changed?
Most manufacturers recommend a transmission fluid change every:
- 30,000 to 60,000 miles for automatic transmissions
- 30,000 to 100,000 miles for manual transmissions (depending on use and vehicle type)
Always consult your owner’s manual for the right interval.
Will They Top Off Transmission Fluid?
Maybe — but only if accessible.
Some quick-lube shops may:
- Check the fluid level
- Top it off if it’s slightly low
- Advise a full flush if it’s dirty or smells burnt
However, some newer vehicles don’t have dipsticks, and checking transmission fluid may require special tools or procedures, which most quick oil change places won’t do on the spot.
Final Thoughts
So, does an oil change include transmission fluid? No — transmission fluid is not changed during a standard oil change. They are separate fluids with different maintenance schedules. While some shops may inspect or top it off, a full transmission service must be requested separately. Keeping both fluids fresh is crucial to your car’s long-term health.
