Summer Heat: How it Affects Your Transmission and How to Protect It

Jul 24, 2023

Summer is often synonymous with road trips and vacation drives. However, amidst the fun and sun, it’s essential to be aware of how the summer heat can impact your vehicle, particularly its transmission. The transmission—your car’s essential component that shifts it into different gears—can be especially susceptible to high temperatures.

Understanding the impact of summer heat on your transmission is crucial for every driver. It allows you to identify potential problems early, perform preventive maintenance, and avoid costly repairs in the future. Plus, this knowledge will enable you to optimize your driving habits according to the season, helping prolong the life of your transmission.

In this blog post, we will explore the relationship between high summer temperatures and transmission health. We’ll also discuss how you can protect your transmission from the heat and ensure its optimal performance throughout the season. As we face the hot summer in Prescott Valley, this is critical information every car owner should have. Let’s get started.

When the summer heat reaches its peak, the temperatures in Prescott Valley can become particularly intense. This extreme heat doesn’t just affect you—it also affects your vehicle, most notably, its transmission. During summer, your transmission is often put through a metaphorical furnace. As the temperature rises, so does the temperature of your transmission fluid. This fluid, which serves as both a lubricant and a coolant for the internal components of the transmission, becomes thinner as it gets hotter. This viscosity change could potentially impair the fluid’s ability to perform its dual roles effectively.

In an ideally functioning transmission system, the fluid smoothly circulates, minimizing friction between moving parts and helping disperse heat. When this fluid thins out due to high temperatures, it may not lubricate the parts as efficiently. Reduced lubrication can lead to increased friction, which, in turn, produces more heat—a vicious cycle that puts excessive stress on your transmission.

Moreover, if your vehicle is subjected to heavy use during summer, such as prolonged drives or towing, the risk of overheating increases. According to the National Highway Traffic Safety Administration, overheating can cause accelerated wear and tear on your transmission components, leading to potential issues like transmission slipping, rough shifts, or even complete transmission failure.

Addressing overheating before it escalates is critical to avoid serious and costly damage. An overheated transmission can even cause damage to other vehicle components, leading to a multitude of problems and repairs that extend beyond just the transmission. 

In extreme cases, ignoring signs of overheating could lead to irreversible damage and the need for a full transmission replacement—a costly procedure that all drivers would prefer to avoid. In the face of summer heat, vigilance and preventive care are your best defenses against potential transmission troubles.

The adage “Prevention is better than cure” holds true when it comes to the health of your vehicle’s transmission, especially during the summer. Regular maintenance and being vigilant about the warning signs of transmission issues are key to preventing costly repairs and potential vehicle downtime.

Maintenance Tips for the Summer 

Proactive care can go a long way in keeping your transmission performing optimally throughout the hot summer months. Regular checks of your transmission fluid are a must. Remember, this fluid plays a critical role in cooling and lubricating your transmission’s internal components. If it’s not at the appropriate level or appears dirty, a fluid change or flush could be necessary. Regularly scheduled maintenance, as recommended by your vehicle manufacturer, can also keep your transmission in good shape. This may include tasks such as filter replacements and band adjustments. If you’re planning a long road trip, having your vehicle inspected by a professional before you head out could save you from potential issues on the road.

Despite your best preventive efforts, transmission problems may still occur. The key is to recognize them early so they can be addressed before causing more serious damage. Watch out for warning signs such as unexplained noises (like humming or clunking), delayed or rough shifting, or a burning smell. Your warning lights are also there to help you. For instance, if the transmission temperature light or check engine light comes on, it’s time to seek professional help. If you notice any of these signs, it’s critical to get your vehicle to a trusted mechanic promptly. Ignoring these signs could lead to more significant issues, such as complete transmission failure, which is considerably more costly to repair.
