A standard transmission fluid change only replaces about 50–60% of your old fluid. Where does the rest go? It stays trapped inside your torque converter and cooler lines!

Here is a quick cheat sheet on the two main services:

🔴 Fluid Change ("Drain & Fill"): Removes fluid from the pan, replaces the filter/gasket, and tops off with 50-60% new fluid—best for routine, scheduled maintenance.
🔵 Transmission Flush: Connects specialized equipment to replace nearly 100% of the fluid throughout the entire system. Best for heavily contaminated fluid or severe driving conditions.

Did you know? Car batteries in San Marcos usually last only 2–4 years, compared to 3–5 years elsewhere.

Why? Summer heat causes three main issues:
🔹 Fluid Evaporation: Exposes internal lead plates to permanent damage.
🔹 Accelerated Corrosion: Destroys internal battery grids.
🔹 Overcharging: Sizzles the battery from the inside out.

Warning signs your battery is struggling:
⚠️ A slow, chugging engine crank
⚠️ Rapid clicking when you turn the key
⚠️ A swollen or misshapen battery case.

Don't wait until you're stuck after a day at the beach! Read our full blog post to learn how simple habits like parking in the shade and avoiding short trips can extend your battery's life.
