Car Transmission Humming: Causes, Symptoms, and Solutions
Introduction
A humming sound coming from your car’s transmission can be a sign of a serious problem. While it’s not always cause for immediate concern, it’s important to have it checked out by a mechanic as soon as possible. In this post, we’ll discuss the most common causes of transmission humming, as well as the symptoms you should look out for. We’ll also provide some tips on how to fix the problem.
What Causes Transmission Humming?
There are a number of things that can cause transmission humming, including:
* Low fluid levels: One of the most common causes of transmission humming is low fluid levels. When the fluid level is low, the gears in the transmission can’t get enough lubrication, which can lead to excessive friction and humming.
* Worn gears: Over time, the gears in your transmission can wear down, which can also lead to humming. Worn gears can’t mesh properly, which can create a humming sound.
* Damaged bearings: The bearings in your transmission help to support the gears and reduce friction. If the bearings are damaged, they can’t do their job properly, which can lead to humming.
* Faulty torque converter: The torque converter is a component of the transmission that helps to transfer power from the engine to the transmission. If the torque converter is faulty, it can cause humming.
Symptoms of Transmission Humming
The most common symptom of transmission humming is a humming sound that comes from the transmission area. The humming sound may be constant or it may only occur when the car is in certain gears. Other symptoms of transmission humming include:
* Difficulty shifting gears: If the transmission is humming, it may be difficult to shift gears. The gears may grind or pop when you try to shift, and you may notice a delay in shifting.
* Slipping gears: If the gears are slipping, the car may lurch or hesitate when you accelerate. You may also notice a loss of power when you’re driving.
* Leaking fluid: If the transmission is leaking fluid, you may notice a puddle of fluid under the car. The fluid may be red, brown, or black.
How to Fix Transmission Humming
The best way to fix transmission humming is to have it diagnosed and repaired by a mechanic. The mechanic will be able to determine the cause of the humming and recommend the best course of action. In some cases, the problem may be as simple as adding fluid to the transmission. In other cases, the mechanic may need to replace the gears, bearings, or torque converter.
