Transmission fluid maintenance?

Hi,

The idea that changing the fluid can be harmful is based on fluid condition. If the fluid in the transmission is extremely dirty and has a burnt smell, a total flush can lead to the transmission slipping. However, with the mileage you have on the vehicle, it is unlikely to be at that point.

Check the fluid condition. It should be a reddish color. If you want, wipe a small amount of the fluid on a white napkin, take a pic of it, and upload it for me to see. I should be able to make a recommendation based on seeing what you have.

Let me know.

Here is an generic guide to help walk you thought eh steps of changing the fluid, which I would just do the drain and fill if the fluid is not too bad.

Fluid Type

Change Automatic Transmission Fluid Only As Necessary.

Generally, it is necessary to change automatic transmission fluid only if your vehicle is driven under one of the Special Operating Conditions listed under one of the Scheduled Maintenance Guide or Owners Manual Supplement.

When changing the automatic transmission fluid, use only "Toyota Genuine ATF WS" (ATF JWS3324 or NWS9638) to aid in assuring optimum transmission performance.

Notice: Using automatic transmission fluid other than "Toyota Genuine ATF Type WS" may cause deterioration in shift quality, locking up of your transmission accompanied by vibration, and ultimately damage the automatic transmission of your vehicle.
