In simple terms, a vehicle’s transmission is responsible for converting the power the engine produces into torque, or rotational force that makes the wheels turn. Without it, the energy generated by the engine would be too strong, making the wheels spin uncontrollably fast. To help you care for this vital car component, here are some frequently asked questions about auto transmissions.

4 Questions About Auto Transmissions

What Are Some Common Transmission Problems?

A low transmission fluid level is probably the most common issue. Whether it’s due to leaks or simply the number of miles you have driven, an insufficient amount of fluid leads to gear slippage, difficulty shifting, and a burning smell, which is a sign of overheating. Issues with the torque converter will often produce a whining or rattling noise while the engine is in gear. For manual transmissions, clutch problems are also common. These can cause violent shaking and lead to a noticeable drop in engine power.

What Steps Can You Take to Prevent Issues?

If you drive a stick shift, make sure you are always in the right gear to match your current speed. Driving fast in low gear and slow in high gear will damage the car. You also should avoid shifting from first gear to reverse and vice versa without coming to a complete stop first, as this can strip the gears.

For both manual and automatic transmissions, let the engine warm up on cold days before you start to drive, use the emergency brake when you’re parked on a hill, and ask your mechanic to check the transmission during your annual appointment.

How Often Should You Change the Transmission Fluid?

To keep your system in optimal health, experts recommend having the fluid changed every 60,000 to 100,000 miles for automatics and 30,000 to 60,000 miles for manual systems. However, you should also check its levels in between service appointments and refill it if necessary, as driving with insufficient amounts of transmission fluid can lead to severe damage.

What Is a Transmission Flush?

This is the process of draining the fluid, using a special machine to run a cleaning solution through the system, and refilling it with new fluid. It is a preventive measure done to flush out grime and sludge, improving the transmission system’s performance and prolonging its life span. While some specialists recommend a flush every 100,000 miles, you should consult your owner’s manual, as the car manufacturer knows what’s best for the vehicle. No matter what, a transmission flush should only be done by a professional.
