How to Check and Add Transmission Fluid

Checking and adding transmission fluid to your 2017 Toyota Sienna is a relatively straightforward process. Here’s a step-by-step guide to help you through it:

  1. Park your Sienna on a level surface and engage the parking brake for safety.
  2. Locate the transmission fluid dipstick, which is usually labeled and located near the engine.
  3. With the engine warmed up and running, 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 appropriate fluid level range.
  5. If the fluid level is below the recommended range, you’ll need to add transmission fluid. Use a funnel to avoid spills and carefully pour the fluid into the transmission fluid filler tube.
  6. Recheck the fluid level using the dipstick, and add more fluid if necessary. Be careful not to overfill.
  7. Once you’ve achieved the correct fluid level, securely reinsert the dipstick and close the hood.

Remember, it’s crucial to follow the specific instructions outlined in your vehicle’s owner’s manual for checking and adding transmission fluid. If you’re unsure or uncomfortable performing this task yourself, it’s always best to consult a professional mechanic.
