Cars have hundreds of components that must work together seamlessly. One such component is the transmission. A transmission is said to “slip” if it refuses to stay in gear or pops into neutral while driving. This is obviously a major safety risk, so you should have the problem diagnosed and repaired as soon as possible.
How to Tell if Your Transmission is Slipping
Here are some signs of transmission trouble to watch out for:
- The tachometer regularly goes above 3,500 RPMs.
- The engine revs, but acceleration is delayed. This can happen from a stopped position or while the car is already moving, such as when accelerating to pass another vehicle on the highway.
- With automatic transmissions, the vehicle has trouble getting up to speed because the transmission won’t shift to the next gear.
- With manual transmissions, the RPMs surge when you shift up, but the car won’t accelerate the way it should.
What Causes a Slipping Transmission?
Many issues can cause a transmission to slip. These may include:
- Low fluid pressure: This prevents the transmission from fully engaging. Low pressure may be caused by bad fluid pumps, clogged filters, or a transmission fluid leak. Many vehicles have a red dipstick in the engine bay for checking the transmission fluid level.
- Burnt fluid: As with engine oil, transmission fluid gets old and needs to be replaced eventually. Once it wears out, the fluid becomes ineffective at removing heat, which may prevent the gears from shifting properly.
- Damaged transmission bands: If these components are worn out, they will literally “slip” when attempting to change gears. Transmission bands wear out over time, but driving gently can help them last longer.
- Clutch problems: In manual vehicles, the clutch is the culprit 90 percent of the time. The clutch disc lasts 20,000 to 200,000 miles depending on your driving habits.
- Worn out gears: Wear and tear can prevent gears from working together properly.
- Solenoid issue: Electrically activated valves, called solenoids, control the flow of transmission fluid. If they are faulty, they can cause shifting delays or failures.
How to Fix a Slipping Transmission
The key to fixing the problem is to pinpoint the cause. If the transmission fluid is low, refilling it should resolve the issue. However, if the transmission starts slipping again, this could indicate a fluid leak that requires repair. If any of the other causes outlined above are to blame, you may need to rebuild or replace the transmission.
