Transmission Fluid: The Blood of Your Car
NaTasha Brand • July 2, 2025
& Why You Should Care
Your car’s transmission is one of its most critical components—and just like your body needs blood to function, your transmission needs transmission fluid to stay healthy. Ignoring it can lead to costly repairs, especially in San Angelo’s hot climate, where extreme temperatures push your vehicle to its limits.
At Ric Henry’s Auto Service, we know how vital transmission maintenance is. That’s why we’re breaking down everything you need to know about transmission fluid—what it does, why it fails, and when to replace it.
What Does Transmission Fluid Do?
Transmission fluid serves several key functions:
• Lubrication: Reduces friction between moving parts to prevent wear.
• Cooling: Helps dissipate heat generated by the transmission.
• Hydraulic Pressure: Enables smooth gear shifts in automatic transmissions.
• Cleaning: Carries away debris and contaminants to keep the system clean.
Without it, your transmission would overheat, grind gears, and eventually fail—costing you thousands in repairs.
How Does Transmission Fluid Work?
In automatic transmissions, fluid acts as a hydraulic medium, allowing gears to shift seamlessly. In manual transmissions, it primarily lubricates gears and bearings. Over time, heat, friction, and contamination cause the fluid to degrade, losing its effectiveness.
Why Does Transmission Fluid Break Down?
Several factors contribute to fluid breakdown:
• Heat: San Angelo’s scorching summers accelerate fluid oxidation.
• Contaminants: Metal shavings, dirt, and moisture build up over time.
• Age: Even if you don’t drive much, fluid loses its protective properties.
That’s why regular flushes and replacements are crucial—typically every 30,000 to 60,000 miles (check your owner’s manual for specifics).
Symptoms of Low or Bad Transmission Fluid
Watch for these warning signs:
• Slipping Gears: RPMs spike but acceleration lags.
• Delayed Shifting: Hesitation when shifting into Drive or Reverse.
• Grinding or Shuddering: Rough gear changes, especially in automatics.
• Burning Smell: Overheated fluid smells like burnt toast.
• Leaks: Puddles of red or brown fluid under your car.
If you notice any of these, bring your vehicle to Ric Henry’s Auto Service before minor issues become major repairs.
