How to Check and Add Transmission Fluid

Now that you know the transmission fluid capacity, let’s discuss how to check and add fluid to your Pontiac G8’s transmission. Here are the steps you need to follow:

  1. Start by parking your vehicle on a level surface and engaging the parking brake.
  2. Locate the transmission dipstick, which is usually labeled and located near the back of the engine compartment.
  3. With the engine running and the transmission warmed up, remove the dipstick and wipe it clean with a lint-free cloth or paper towel.
  4. Reinsert the dipstick fully and then remove it again to check the fluid level. The dipstick will have markings indicating the proper fluid level range.
  5. If the fluid level is below the recommended range, you will need to add transmission fluid. Use a funnel to pour the fluid into the dipstick tube, being careful not to overfill.
  6. Recheck the fluid level using the dipstick and add more fluid if necessary. Remember to always add fluid in small increments to avoid overfilling.
  7. Once the fluid level is within the recommended range, securely reinsert the dipstick and close the hood.

It’s important to follow these steps carefully and ensure that you are using the correct type of transmission fluid. If you are unsure or uncomfortable performing this task yourself, it is always best to consult a professional mechanic.


Keeping your Pontiac G8’s transmission fluid at the proper level is essential for maintaining its performance and longevity. By using the correct type of fluid and following the recommended capacity, you can ensure that your transmission operates smoothly and efficiently. Remember to regularly check your fluid levels and top them up as needed to avoid any potential issues down the road. Take care of your Pontiac G8, and it will take care of you on the road!
