The Spanish phrase "transmisiones automáticas" translates to "automatic transmissions" in English. An automatic transmission consists of many components and systems that work together to send power from the vehicle's engine to the drive wheels.
Owners of vehicles with automatic transmissions need to learn to detect problems early before the problems become serious. A red oil stain under the vehicle indicates a leak in transmission or power steering fluid. Owners should check transmission fluid when the vehicle is running and on level ground, and the fluid should look like cherry cough syrup. If the fluid has a burned odor or appears muddy or cloudy, the transmission needs to be drained, tuned up and filled with fresh fluid. The transmission should shift smoothly under light acceleration. If shift points are erratic, the transmission needs to be checked immediately by a technician.
