Will changing the auto transmission fluid help?

Hi,

As it has never been changed, it certainly won’t hurt the transmission by changing the fluid with the correct replacement fluid, (see 2nd image for details). If there are any metal flecks floating in it they will only cause more damage as time goes by not less.

According to the maintenance schedule from the owners manual for your vehicle the automatic transmission fluid should be inspected every 15,000 miles and changed every 30,000 miles (or 2 years) if towing a trailer, using a camper, using a car top carrier or driving on rough or muddy roads.

Here’s an image taken from the owners guide that details this
