When it comes to your vehicle’s transmission, it can be difficult for the average driver to know how to identify problems. If you drive an automatic vehicle, your vehicle’s transmission system is a complex mechanical system that can be inconvenient and costly to repair. However, being aware of common transmission issues and proactively getting a trained mechanic to perform maintenance checks can help ensure that your vehicle continues to perform its best for as long as possible.


Knowing what to look for with transmission issues can help you diagnose car troubles and get them properly fixed. Here are some common transmission problems and how to identify them:

  • Transmission Slipping: Automatic transmission slipping can feel like the gear you are driving in changes for no apparent reason. Your engine may start making a whining noise or change its pitch. You may also notice your vehicle seems underpowered or struggles to accelerate.
  • Rough Shifts: If your vehicle feels like it won’t change gears as it normally does, or the gear shifts are not smooth, you may be experiencing rough shifting issues. In some cases, you may be able to feel or hear an audible “thud” when the car shifts gears. It may also be difficult to get your car up to speed.
  • Delayed Engagement: If you notice a delay before the car engages into ‘drive’ mode and starts moving forward, there may be a more complex issue. When you shift out of ‘park’ into ‘drive’, any pause or delay experienced as the car revs the engine but does not move forward should be looked at by a professional.
  • Fluid Leak: Transmissions are sealed and should never leak fluid. If you notice spots on your driveway, place cardboard under the front and middle of your vehicle to determine if the leaks are active. If you see fluid that is bright red, dark red or brown, it may be transmission fluid. Visit your auto service shop. Follow factory specifications before refilling any transmission fluid, or visit a professional, since overfilling can cause more serious issues.
  • Warning Light: A warning light alone does not usually indicate a transmission problem, but when a warning light is combined with another issue outlined above, it may reveal a more serious issue and should receive professional attention as soon as possible. For transmissions, “P0700” is typically the code that indicates a general transmission issue.
