  1. Park your Sienna on a level surface and engage the parking brake.
  2. Locate the transmission fluid dipstick. It is usually labeled and can be found near the back of the engine compartment.
  3. With the engine warmed up and running, shift through each gear position, pausing for a few seconds in each, before returning to Park.
  4. Remove the dipstick, wipe it clean, and reinsert it fully into the dipstick tube.
  5. Remove the dipstick again and check the fluid level. It should be within the “Hot” range on the dipstick.
  6. If the fluid level is low, carefully add small amounts of the recommended transmission fluid through the dipstick tube. Recheck the level frequently to avoid overfilling.
  7. Once the fluid level is within the appropriate range, securely reinsert the dipstick.

Remember, it is crucial to follow the manufacturer’s recommendations and specifications when it comes to transmission fluid. Using the wrong type or overfilling can lead to serious damage to your vehicle’s transmission system.
