Transmissions are highly complex vehicle systems that convert the engine's combustion power into physical momentum. They ensure that the engine spins at the correct speed and the wheels get the correct distribution of power. However, slipping is one of the more common issues a transmission may develop, and it's a sign for drivers that it's time to schedule a transmission service appointment. Here are some common questions people have about transmission slipping.

A Guide to Transmission Slipping

What are the signs?

As you drive, monitor your vehicle's revolutions per minute (RPM), as 3,500 RPM is definitely a cause for concern. Another sign to watch out for is the engine revving without accelerating. After all, delayed acceleration could mean that the transmission is not switching from one gear to the next. Be sure to look out for grinding or other strange noises, as well as any burning smells. Lastly, if you have a manual transmission, you may notice difficulty shifting gears. 

Will my car drive differently?

Your car may seem less responsive when you try to accelerate. This is because, when the transmission slips, it isn't able to distribute power to the tires. This may cause your wheels to spin and RPM to increase without the car gaining speed. You may also notice a jerking or surging movement while the wheels receive small bursts of power as the transmission slips.

Why does transmission slipping occur?

One of the most common reasons for transmission slipping is low or dirty transmission fluid. This fluid should be checked and changed on a regular basis according to the manufacturer's recommendation. During transmission service, a technician will top off, or flush and change out, your vehicle's fluid to ensure a healthy transmission system.

Other reasons your transmission may be slipping include worn transmission bands, issues with the clutch, damaged or worn gears, or torque converter problems. 

When should I schedule repairs? 

If well-cared for, a transmission can last for 100,000 miles or more. Transmission services are recommended every 30,000 to 60,000 miles to replace the transmission fluids and filter, check for leaks, and run diagnostics.

In addition to regular maintenance, visit an auto mechanic right away if you notice any of the issues listed above.

Why are transmission solenoids important?

The transmission solenoid is an electromechanical valve that controls the flow of fluid in the transmission. When gears are shifted, the vehicle's computer activates the solenoid and pushes fluid into the valve body of the correct gear to engage it. 

If the solenoid is malfunctioning, you may experience difficulty shifting gears. Impeded fluid flow can lead to gears overheating and slipping. It might also trigger the engine light, alerting drivers to check their engines. An auto mechanic can determine if there is a defective solenoid that needs to be replaced.
