If you are experiencing any of the following issues, you could need transmission repair:

  • Vehicle shaking while driving
  • A burnt smell from under the hood
  • Dark red or brown liquid leaking from your vehicle
  • Your manual gear shifter won’t go into gear or is physically hard to move
  • Transmission slipping, jumping, or grinding while the car is accelerating
  • Pauses while shifting

You can also check your transmission fluid with a dipstick. If the fluid is foul smelling, thick, or cloud, it could need a flush. At Johnny’s Auto Service, we know transmissions inside and out, whether you need a small fix or a rebuild of your entire transmission.
