Changing your car’s transmission fluid is a task best left to professionals, such as your nearby Forest Lake auto service center. Unlike changing your oil, this job requires specific expertise.
Opting for professional service is a smart choice that can save you the high cost of transmission repairs.
But what happens if you neglect it? How frequently should you replace the transmission fluid? This guide answers these questions and helps you recognize potential transmission issues before they cause significant problems.
Engine Performance Relies on Transmission Fluid
Regardless of whether your vehicle has an automatic or manual transmission, shifting gears generates friction and heat.
Transmission fluid plays a vital role in this process, ensuring smooth operation with minimal wear on engine components.In automatic transmissions, the fluid serves as a lubricant, hydraulic fluid, and coolant.
For manual transmissions, while it doesn’t act as a coolant, the fluid still lubricates and provides essential hydraulic pressure to maintain optimal engine performance.
The Degradation of Transmission Fluid
As transmission fluid circulates continuously through the system, it undergoes wear and tear. Automatic transmissions, in particular, generate intense heat that can eventually degrade the fluid.
In both automatic and manual systems, wear on components like gears, bearings, and synchronizers introduces tiny metal shavings into the fluid.
Over time, this contamination accelerates the breakdown of the transmission fluid.The decline of transmission fluid isn’t immediately noticeable, as the process is gradual.
However, when the fluid fails, it can lead to severe transmission damage. Be aware of these warning signs that indicate transmission fluid problems:
- Unexpected or repeated gear slippage
- Sudden power surges
- Delayed response when shifting gears
- Squealing noises during gear shifts
- Difficulty shifting gears in a manual transmission
- Overheating without an apparent cause
- Fluid color changing from red to brown
- Puddles of brown fluid under your parked vehicle
Knowing When to Replace Transmission Fluid
The frequency of transmission fluid changes depends on your driving habits. Generally, it’s recommended to replace the fluid every 30,000 to 60,000 miles or every two to four years.
For manual transmissions, consider sticking to the lower end of this range. If your vehicle frequently tows or hauls heavy loads, you should change the fluid every 15,000 miles.
