How To Stop Transmission Whine?

On the off chance that your vehicle is making a whiny sound that you suspect is coming from the transmission, don’t stand by to sort out the cause of the sound as it can be damaging. The sound in your vehicle is in every case, is possibly the sound of harm that has been done. It could be scratching or grinding of parts that wear out and lead to fixes later on.

Learn how to stop transmission whine with the help of common diagnoses and solutions in our article.

How To Stop Transmission Whine?

The points given below gives hints about where to start for potential problems in your transmission. If you follow these steps, you can track it down and get on the road faster.

1. Automatic Transmission Noises

Automatic transmissions have more tightly controlled parts than manual transmissions, so there are more possible causes of commotion, which implies there are more likely kinds of sounds when something gets wrong. While learning about how to stop transmission whine, here are some common solutions-

1. Low Fluid Level

Whining sounds at whatever point the vehicle is moving can be caused due to low fluid levels in the transmission. At times the sound is due to the cogwheels slipping in the transmission. This typically shows burnt/old liquid or a low liquid in the case. You should not drive too much in this condition as it may cause expensive damages.

This problem can be solved by changing the transmission fluid. Makes sure that you replace it with proper fluid which is recommended by the manufacturer. If the fluid checks out, then the problem may be the oil pump inside the transmission.

2. Torque Converter Gone Bad

The torque converter is a transmission component, that is responsible for acting as a coupling between the engine and the transmission. As automatic vehicles do not have a clutch, the torque converter fills this role and provides necessary slipping. The most common problem of the torque converter is caused due to overheating. Any drop in fluid pressure within the torque converter will lead to heat build-up within the transmission.

These issues can contribute to the failure of the torque converter, which includes damaged bearings and seals, or a damaged solenoid. Only an experienced mechanic can be trusted to replace a damaged torque converter.

3. Bad Transmission

While operating your vehicle, you may notice a whining sound coming from your transmission. The whining noise that comes from your transmission can be caused due to a variety of potential causes. It is difficult to pin down the issues without help from a professional. If the transmission has gone bad, then a whole transmission teardown is required.

The solution will require a transmission overhaul, that requires the removal and disassembly of the transmission in its completion. Every part of the transmission should be inspected for wear and damage. It is cleaned in a cleaning solution or replaced with a new part, depending on its condition.

4. DSG Mechatronic Failure

The mechatronic unit is the control center of the DSG transmission. Its task is to manage the clutch pad of the gearbox via the transmission fluid, which is achieved under specific pressure. A failed mechatronic unit can cause whining noises when shifting gear. The electronic unit is comprised of sensors and actuators in one single part a failed unit will not promote smooth function.

The common problem occurring in the control units is the incorrect solenoid operation and periodic errors. Sensors can also get faulty, the mainboard may get damaged. The only solution is to replace the unit. 

2. Manual Transmission Noises

Manual transmission can also develop issues as a result of high mileage, abuse, or lack of proper maintenance, but they’re rather rare. Most manual transmission problems can also be due to ancillary parts such as clutch or differential. Common causes are-

1. Transmission Oil Issues

The most common cause of a loud transmission is having low oil levels, and it can be a common solution for how to stop transmission whine. It will cause the gears or internal assembly to start to hum or whine. If a loud transmission does not have enough oil, the transmission could also be contaminated with metal shavings or particles.

It is likely that some permanent damage has occurred due to the constant running of low fluid levels. The common solution would be to replenish the transmission with some new fluid, that is specifically recommended for the transmission type and temperature region.

2. Damaged Synchronizer

Terrible synchro means somewhat of grinding vibe and whining sound when you shift, up or down, yet more frequently down. Normally, it will begin with moving down to first gear while moving gradually or coming toward a stop. The sound you depict seems like a metal-to-metal contact.

The solution would be to attempt a transmission overhaul, replace the worn-out components, and wash the whole system. It requires a qualified technician to do the job.

3. Worn Out Differential Gear

The failed differential is the most common sound of whining noise, which can be mistaken as a transmission noise. This is often due to poor lubrication within the differential, meaning there is a good chance that the differential fluid is leaking. If you spot a reddish fluid under the differential, there is certainly a leak. Replacing them is the only option. 

4. Clutch Throwout Bearing

The clutch release bearing, some of the time called a throw-out bearing, is a straightforward yet significant segment that is used when the clutch pedal is operated. At the point when you have a terrible bearing, it will influence moving and can prompt a bad grip and transmission will start to whine. Replacing them with a new one will solve the problem.

How Much It Cost To Fix Transmission Issues?

Typically, a transmission overhaul job is an expensive job and can burn a hole in your pocket. It can easily cost upwards of 1000$. Replacement of transmission fluid is cheap at 100$ range. Other miscellaneous jobs can be done for under 500$.


It is easy to learn how to stop transmission whine and fix that too. The problem mostly originates when you are not taking care of your periodic maintenance, so stick to them. If you have any further doubts, then comment down below.
