Transmission Slipping: Signs and Solutions

Can I Sell A Car That Is Not Running?

If you own a car, you are probably familiar with the sinking feeling that comes with transmission problems. You may notice your car hesitates or lags when shifting gears, making an unnerving noise or refusing to move at all. These are all signs of a transmission issue, specifically “transmission slipping.”

Auto Repairs Are EXPENSIVE

Transmission slipping occurs when the transmission fails to maintain an appropriate gear, and the car may fail to accelerate. The root cause of slipping is often due to low fluid levels or dirty, worn-out transmission fluid. To help you understand more about transmission slipping, we've put together a guide that outlines the signs, causes, and solutions.

Signs of Transmission Slipping

The signs of transmission slipping are easy to spot. If you experience any of the following signs, you may have a slipping transmission:

  • Your car hesitates or struggles to accelerate.
  • Your car revs up, but the speed does not increase.
  • You hear strange grinding or whining noises when shifting gears.
  • Your car jerks or makes a jarring motion when shifting gears.
  • Your car suddenly loses power and stops moving altogether.

Causes of Transmission Slipping

Several factors can cause transmission slipping. Here are the most common causes:

Low Transmission Fluid

Transmission fluid is critical to maintaining a smooth transmission. When fluid levels are low, the transmission can slip, resulting in erratic shifting and other transmission problems.

Worn-Out Clutch

If the clutch is worn out, it will not maintain proper tension, resulting in slipping transmission. Clutches wear out over time, so it's important to have your clutch inspected regularly.

Dirty Transmission Fluid

Dirty transmission fluid can cause the transmission to slip or malfunction. Dirty fluid can also cause other transmission issues, such as overheating.

Faulty Transmission Solenoid

The transmission solenoid controls the transmission fluid flow. If it fails, the fluid may not flow correctly, causing the transmission to slip.

Solutions for Transmission Slipping

There are several ways to address transmission slipping, depending on the root cause. Here are some solutions:

Refill Transmission Fluid

If the transmission fluid is low, refilling it may be the solution. However, it is essential to check for leaks and repair them to avoid further issues.

Replace Worn-Out Clutch

If the clutch is worn out, it will need to be replaced. Have your clutch inspected regularly to avoid unexpected failure.

Change Dirty Transmission Fluid

Changing the dirty transmission fluid can fix many transmission issues, including slipping. Regular fluid changes are essential to maintain a healthy transmission.

Replace Faulty Transmission Solenoid

If the solenoid is faulty, it will need to be replaced. A professional mechanic can diagnose and fix this issue.


Transmission slipping is a common problem that can be caused by several factors, including low fluid levels, worn-out clutch, dirty fluid, and faulty transmission solenoid. Recognizing the signs and addressing them promptly can help you avoid costly repairs and keep your car running smoothly. If you experience any of these symptoms, take your car to a professional mechanic for a thorough inspection.
