1. Gather your materials. You will need:
* Transmission fluid (use the type recommended by your owner's manual)
* A funnel
* A clean rag
2. Prepare your vehicle. Park your Cobalt on a level surface and turn off the engine. Set the parking brake.
3. Locate the transmission fluid fill plug. The fill plug is located on the side of the transmission, near the top. It is usually marked with a red or orange cap.
4. Unscrew the fill plug. Use a wrench to loosen the fill plug. Be careful not to drop the plug into the transmission.
5. Insert the funnel. Insert the funnel into the fill hole.
6. Add transmission fluid. Slowly add transmission fluid to the funnel until it reaches the "Full" mark on the dipstick. Be careful not to overfill the transmission.
7. Replace the fill plug. Once you have added the correct amount of transmission fluid, replace the fill plug. Tighten the plug until it is snug.
8. Check the transmission fluid level. Use the dipstick to check the transmission fluid level. The fluid should be between the "Full" and "Add" marks on the dipstick.
That's it! You have now successfully added transmission fluid to your 2010 Chevy Cobalt.
