Manual and automatic transmissions share some warning signs that you must be aware of.
First off, notice the pinkish-red leaking transmission fluid. If you learn that the fluid is collected on the ground while you are having your parked vehicle moved, then it is ideal to have it inspected. Take note that the leaking fluid means you must attend to the failure or problem.
Just the same, if the fluid becomes dark brown or black, this means the fluid is burning up while the shifting is being done and you need to work on it.
If you encounter having delays when shifting the gear, it is time to go for a car inspection. The gap between the time you shift gear and the time the car acts based on the gear may mean a total transmission failure.
