What Are the Reasons for Car’s Rattling Noise When Accelerating?

A torque converter job is a huge undertaking. It involves removal of the transmission so that the vehicle’s torque converter can be thoroughly inspected- and then replaced if need be.

Could it Be The Motor Mount?

That motor mount may be ruptured and leaking fluid as far as the eye can see. One way to pinpoint this issue, is to look for dark lines of dripping oil that may be on the frame next to the side mount or underneath. It may be a bit difficult to determine the failure with just a look- especially if there are no oil stains. You’ll have to take your car to a mechanic for a proper diagnosis.

Have You Checked Your Vehicle’s Transmission Levels? 

Although not a major or huge issue, it may be to your benefit to check your transmission fluid levels. The vehicle’s fluid should be at a level that the vehicle’s manual recommends. Low fluid levels in the transmission are but one of many reasons that a car can rattle during acceleration. 

 

Solution To The Transmission Issues You Are Having 

If you are a car owner, who routinely changes your transmission fluid every 30,000, 40,000 or even 60,000 miles, then you should never have an issue with your transmission or its fluid levels.

You will notice that a belt is bad if you see damage in the form of frayed or tattered sides.

Are Your Vehicle’s Heat Shields Loose? 

If your vehicle’s heat shield becomes broken, damaged or even loose, because of rust or some other issue, then that heat shield will vibrate and cause a rattling sound. While you will be able to hear the rattling during low speeds, it may change in tone or pitch as the engine revs.  A mechanic will need to inspect your heat shield. Many vehicle heat shields will last the entire lifespan of the vehicle.

Perhaps There is an Issue With Your Valve Train System 

Is your car making rattling noises that sound like bottles making clinking sounds? Then chances are you have an issue with your valve train system. The valve train system in your vehicle has the task of operating both the exhaust as well as the intake valves. Any worn or stuck parts- even the hydraulic lifters- may cause ignition that is premature in the combustion chambers. Many refer to this premature ignition as carbon rap and can be traced to filing your car with fuel that is the incorrect octane level or just dirty oil. 

 

Solution To The Issue of the Valve Train 

If your valve train- which you can find at the top of your vehicle’s engine- is the cause of your car rattling, then you need to see what kind of oil you are using in your car. For oil that is dirty, then an oil change may be all you need to end the rattling. You can also starve off the rattling by putting the correct fuel in your car. For example, if your car only accepts 95 octane and you are using a lower grade such as 89, then this may contribute to the rattling you hear.
