How to Check and Add Transmission Fluid

Checking and adding transmission fluid is a relatively simple task that you can do yourself. Here’s a step-by-step guide to help you through the process:

  1. Start by parking your Buick Park Avenue on a level surface and engaging the parking brake for safety.

  3. With the engine running and the transmission in “Park” or “Neutral,” remove the dipstick and wipe it clean with a lint-free cloth.
  4. Reinsert the dipstick fully and then remove it again to check the fluid level. The dipstick will have markings indicating the “Full” and “Add” levels.

  6. Recheck the fluid level using the dipstick, and repeat the process until the fluid reaches the appropriate level.
  7. Once you’re satisfied with the fluid level, securely reinsert the dipstick and close the hood of your Buick Park Avenue.
