What are the Symptoms of an Automatic Transmission Problem?


A Check engine light can be as sign of many different issues depending on your vehicle’s make and model. When you get a check engine light, even though it’s called a check “engine” light, it doesn't necessarily point directly to your engine. It could be your transmission, brake system, air conditioning, or really any system on the vehicle, so it's important you have the codes retrieved from the vehicles computers to allow for a pinpoint diagnostic of the system and problem. If the light is flashing, that could mean a severe problem that is causing other damage to the engine and or transmission so do not delay.

Science tells us odd sounds and vibrations point towards deep lying issues with friction between surfaces. Your transmission is no different. Since your vehicle’s computer tells the transmission when to shift, and the transmission automatically does the shifting, shaking or grinding is a good sign that your transmission needs attention. In many cases shaking and grinding is a result of damage to the planetary gear system, a bearing issue, or sometimes it is outside of the transmission in the Ujoint, halfshaft or even your engine.

If there is an odd sound emitted from your transmission only while you're in neutral and not moving, that is a clear indication that your transmission or engine could be the culprit. The most common issues include the following:

  • Transmission solenoid problems
  • Low or dirty fluid
  • Clogged transmission filters
  • Issues with clutches or torque converter
  • Transmission cooler issues
  • Engine control problems

If there is an odd sound emitted from your transmission only while you're in neutral and not moving, it is a clear indication that your transmission or engine could be the culprit. The most common issues include the following:

  • Worn bearings
  • Worn or broken internal transmission parts
  • Loose exhaust system
  • An engine problem

In most cases, a burning smell comes from very hot leaking transmission fluid or other fluids. Preventing this requires checking your fluid levels regularly for indications of a leak. Low fluid levels often cause major problems with your vehicles mechanical systems if you don’t catch them quickly.

Transmission leaks are probably the second most common transmission problems that lead to major internal transmission issues. Most transmission leaks occur due to a leaking pan gasket, worn axle or driveshaft seal, or a leaking transmission cooler, cooling line or O-ring. These leaks will ultimately cause low burnt fluid, overheating and major damage that cannot be repaired by just adding fluid back into the transmission.

If you spot a leak in your transmission, look to see if you can spot where it is coming from. Repairing a cooling line or a pan gasket can be a quick, somewhat inexpensive solution if caught quickly. An axle seal, shaft seal or converter seal is a bit more work, but if you catch the leak soon enough before internal damage can occur, you’ve probably saved yourself a bunch of money for a replacement or rebuilt transmission.

Frequently Asked Questions


Over time, your transmission fluid heats up and cools off many, many times, and as it does its job of providing lubrication and hydraulic pressure, it will slowly degrade and become less protective. With age, it also becomes contaminated with worn material and other possible contaminants.

Every vehicle owner should have an owner’s manual and maintenance guide that came with the vehicle from the manufacturer. This guide will outline when, and how often, your vehicle’s fluids should be serviced. A good rule of thumb is an automatic transmission’s fluid should be exchanged anywhere from 60,000 and 100,000 miles depending on how you drive and what you drive. Not maintaining your transmission properly and regularly can result in a lower transmission lifespan. Check your transmission fluid level between service intervals to make sure you don’t have a leak and run low.

If your transmission is regularly maintained as per the manufacturer’s recommendations, it’s not uncommon for transmissions to last anywhere from 100,000 to 200,000 miles. Some types of transmissions are more durable than others so check your maintenance schedule for the proper intervals.

Many manufacturers of hybrid vehicles continue to use conventional or CVT style automatic transmissions, while others have developed a drive system that is primarily made of the electric motors and planetary gear sets used to propel the vehicle. Most pure electric vehicles no longer have transmissions, with the electric propulsion motors attached directly to the axles or wheels.
