Why Transmission Maintenance Matters

The transmission is the crucial component that allows your vehicle to move and shift gears smoothly. When it fails, you face significant time off the road and massive repair bills. Fortunately, protecting this vital system is easier than you might think. By following a few key steps, you can greatly extend the life of your transmission.

Your Two Most Important Tasks

The life of your transmission boils down to two things: fluid quality and fluid level. Metal wear and extreme heat generated during driving contaminate transmission fluid over time. Contaminated or low fluid is the primary cause of transmission failure.

Key Maintenance Steps:

• Keep the Fluid Clean: It is essential to replace your transmission fluid and the filter at manufacturer-recommended intervals. The filter traps harmful metal fragments and contaminants. A simple drain-and-fill replaces only some of the fluid; consult your owner’s manual to see if a full flush is required for your vehicle.
• Maintain Full Levels: Low fluid levels quickly lead to serious damage from excessive friction and heat. Always check for leaks. If you notice fluid on your driveway, have it inspected immediately.
• Stop Before Shifting: Never shift gears (like from Drive to Reverse) while the car is still moving. Coming to a complete stop prevents undue strain on the transmission components.
• Check the Color and Smell: Good transmission fluid is typically vivid red or pink and smells sweet. If your fluid is murky, dark, or smells burnt, it is a sign of severe problems and requires immediate professional attention.

It is always best to check your vehicle owner’s manual for specific fluid types and recommended service intervals, as these vary widely by make and model.
