Servicing Your Automatic Transmission

Your automatic transmission is the most complicated piece of machinery on your vehicle, and it controls the application of power from the engine to the driveshaft. Transmissions can last a couple hundred thousand miles, if cared for and maintained properly.

Major problems may come up if your transmission is not periodically serviced or maintained. Here are things to watch out for which tell you that you need to take it in for an inspection.

Lack of Response – Does your vehicle hesitate or refuse to go into gear? If it does, then there is definitely something wrong.

Whining, Clunking and Humming – the best way to describe transmission sounds of trouble is that you may hear a humming, buzzing or whining noise which is unfamiliar to you.

Leaking/Low Fluid – Letting the trans fluid keep leaking is one of the most common causes of an eventual transmission break down, so fix leaks immediately.

Grinding or Shaking – If the grinding occurs after engaging the clutch and shifting, this can be sign that the clutch may need to be replaced or adjusted.

Burning Smell – Overheating transmission fluid is one of the causes of a “burning smell”. When your trans fluid breaks down, it will run too hot which results in more friction.

Refuses to Go Into Gear – If the car will not shift after engaging the clutch and trying to move the shift lever, take a look at the trans fluid to make sure that it is up at the full mark.

Transmission Noisy in Neutral – a transmission that is noisy and goes “bump” when it is in neutral might be corrected such as adding some fluid or changing it. However be sure to have it checked out.

Gears “Slipping” – The cause can be the link that holds the gears in place is worn or broken or other worn parts. Get your vehicle inspected and repaired as soon as possible.

Major expensive transmission repairs can be avoided if the vehicle is properly maintained, and especially true if and when you notice something out of the ordinary. The car should be taken in immediately for service.
