The transmission is just as vital to an automobile as the engine. It brings the power from the engine to the wheels through a series of gears. The transmission is the most complex component in your automobile. It may have as many as a thousand parts, each having to function perfectly with the others in order to work properly.

Some signs of a failed or failing transmission are:

  • Irregular shifting - unpredictable shifts while driving
  • Rough shifting - abrupt shifting between gears
  • Slippage - this is when your vehicle speeds up, but the vehicle doesn’t respond to it
  • Stains where you park - red stains under the vehicle
  • Grinding sounds
  • Vibrations through the car
  • Check engine light illuminated
  • Dirty fluid - transmission fluid should be red and if it isn't, it's dirty and that's a problem

If experiencing any of these signs, it is critical to take your vehicle to Roy Brothers as soon as possible.
