Understanding Transmission Fluid

Transmission fluid plays a vital role in your vehicle's operation. It acts as both a lubricant and a coolant, reducing friction between moving parts and helping to maintain optimal operating temperatures. Over time, this fluid can degrade or become contaminated, leading to potential transmission issues. For the 2018 Chevy Colorado, it is essential to use the correct type of fluid, typically Dexron VI, as specified in the owner's manual.

Regularly checking and maintaining the transmission fluid level is important. If you notice any signs of low fluid levels—such as rough shifting, unusual noises, or dark-colored fluid—it’s time to add more.

Tools Required

Before you start adding transmission fluid, gather the following tools and materials:

  • Transmission fluid (Dexron VI)
  • Funnel or fluid pump
  • Rags for cleanup
  • Safety gloves (optional)
  • Catch pan (if needed)

Having these tools ready will make the process smoother and prevent spills.

Steps to Add Transmission Fluid

Adding transmission fluid to your Chevy Colorado involves several straightforward steps. Follow these carefully to ensure you do it correctly.

Step 1: Prepare Your Vehicle

Ensure your vehicle is parked on a level surface and that the engine is running at operating temperature. This allows for an accurate reading of the fluid level.

Step 2: Locate the Fill Port

The fill port for the transmission fluid is typically located on the side of the transmission case. For models without a dipstick, you will need to use a pump or funnel:

  • Identify the fill plug: This is usually a small bolt or cap on the side of the transmission.
  • Remove the fill plug: Use a wrench or socket to loosen and remove it carefully.

Step 3: Check Fluid Level

Before adding new fluid, it’s wise to check the existing level:

  • Insert a clean finger into the fill hole (if accessible) or use a dipstick if your model has one.
  • The fluid should be bright red and should not have a burnt smell.

Step 4: Add Transmission Fluid

Using a funnel or pump, slowly add new transmission fluid into the fill port:

  • Pour in small amounts at first.
  • Check frequently to avoid overfilling.
  • The total capacity for your vehicle is approximately 10-12 quarts, but only about 4-5 quarts can be added during a standard service.

Step 5: Replace Fill Plug

Once you have added enough fluid (the level should be just below the fill hole), replace and tighten the fill plug securely.

Step 6: Clean Up

Wipe away any spilled fluid with rags to prevent slipping hazards.

Step 7: Test Drive

After adding the fluid, take your Colorado for a short drive. This helps circulate the new fluid throughout the system. After driving, check again for leaks around the fill port.

Common Mistakes to Avoid

When adding transmission fluid, be cautious of these common pitfalls:

  • Overfilling: Adding too much fluid can cause foaming and lead to erratic shifting.

  • Using Incorrect Fluid: Always use Dexron VI or low-viscosity ATF as specified in your owner’s manual.

  • Neglecting Regular Checks: Make it a habit to check your transmission fluid monthly or before long trips.

Signs You Need More Transmission Fluid

Keep an eye out for these indicators that may suggest low transmission fluid levels:

  • Rough or delayed shifting
  • Unusual noises from the transmission
  • Dark or burnt-smelling fluid
  • Slipping gears during acceleration

If you notice any of these symptoms, it’s crucial to check and add transmission fluid as soon as possible.
