## 🧠 What Is Gearbox Fluid and Why Is It Important?
Your gearbox (also called the transmission) is responsible for transferring power from the engine to the wheels. Inside are many moving parts—gears, shafts, clutches, bearings—that rely on fluid for:
– **Lubrication** – Reduces friction and wear between metal components
– **Cooling** – Helps dissipate heat generated by gear movement
– **Hydraulic pressure** – In automatics, it’s used to apply clutches and bands
– **Cleaning** – Carries away metal particles and debris into the filter or pan
Over time, gearbox fluid:
– Breaks down from heat and friction
– Becomes contaminated with metal shavings and debris
– Loses the additives that protect parts
When that happens, you may notice:
– Hard or rough shifting
– Slipping gears
– Whining or humming noises
– Delayed engagement when shifting into drive or reverse
Changing the gearbox fluid on schedule helps **extend gearbox life** and **avoid expensive transmission repairs or replacements**—which can cost thousands.

Some cars have sealed transmissions and no dipstick. If yours does have a dipstick, you can do a basic check:
1. Park on level ground and set the parking brake.
2. Start the engine and let it warm up (some vehicles require checking hot; verify in your owner’s manual).
3. Shift through all gears slowly, ending in Park (or Neutral if recommended).
4. Pull the transmission dipstick, wipe it clean, reinsert, and pull again.
5. Check:
– **Level** – Should be within the recommended range.
– **Color** – Healthy fluid is usually **bright red or pink** (or light amber for some types).
– **Smell** – Should not smell burnt or extremely sharp.
If it’s low, dark, or burnt, have a professional inspect it.
