Cambio de aceite de la transmisión
An essential task

Transmission fluid is a hydraulic fluid essential for the proper functioning of the automatic transmission. Its functions include lubricating gears and clutch assemblies, reducing friction and heat, and regulating system temperature
Most traditional automatic transmissions require a specialized fluid to operate smoothly. This fluid circulates throughout the system, cleaning it of any contaminants that could cause engine malfunctions. Several types exist: CVT fluid: Used in continuously variable transmissions, which operate with belts and pulleys instead of traditional gears.
- DCT fluid
- Used in dual-clutch transmissions, it is a hybrid between manual and automatic transmissions.
The owner’s manual will guide you to the correct fluid type for your car’s make and model and indicates the recommended change interval. The fluid should be replaced between 90,000 and 160,000 km (60,000 to 100,000 miles) or if the car exhibits the following symptoms:
- 1. Shifting or difficulty shifting gears.
- 2. Delay when shifting from park to drive (in automatic vehicles).
- 3. Grinding when shifting gears.
It’s a good idea to check the transmission fluid level gradually using the dipstick. In rear-wheel drive (RWD) vehicles, it’s usually located at the rear of the engine compartment, while in front-wheel drive (FWD) vehicles, it can be found near the side of the engine.
Esta varilla suele ser brillante (a menudo roja, amarilla o naranja) o estar marcada con un símbolo de transmisión, fácil de detectar para comprobar los niveles de líquido si es necesario. Algunos vehículos modernos ya no la traen y requieren un mecánico o una herramienta de diagnóstico para comprobar o rellenar el fluido.
Start the car to warm up the transmission fluid, then turn it off and proceed with a safe task.
Find a clean space and raise the car with a hydraulic jack and leveling stands to ensure proper operation.
Locate the transmission drain plug under the car, place a waste container underneath. Remove the plug and drain the fluid.
Check that the transmission fluid pan is in good condition, replace it if it is not, and put it back in place.
Pour the fluid back in by connecting a pneumatic filler to the drain plug or a funnel and pumping until full, then seal the drain plug.
Restart the engine and test drive the car.
