If you’re wondering how to check and add transmission fluid to your 2005 Cadillac CTS, follow these steps:

  3. With the engine still running, pull out the dipstick and wipe it clean with a lint-free cloth or paper towel.
  4. Reinsert the dipstick fully and pull it out again to check the fluid level. The dipstick will have markings indicating the minimum and maximum levels.
  5. If the fluid level is below the minimum mark, it’s time to add some transmission fluid.
  6. Using a funnel, carefully pour the recommended transmission fluid into the dipstick tube. Be cautious not to overfill, as it can lead to transmission issues.
  7. After adding fluid, recheck the level using the dipstick. Repeat the process until the fluid level reaches the appropriate range.
  8. Once you’re satisfied with the fluid level, securely reinsert the dipstick and close the hood.

Remember, it’s essential to use the correct type of transmission fluid recommended by Cadillac for your 2005 CTS. Consult your owner’s manual or contact a certified Cadillac technician if you’re unsure about the specific fluid type.
