Does anybody know where you check to fluid for the automatic transmission on a 4.7 motor. There is no dipstick? Also I checked the scheduled maintenance manual and it does not show the service interval time frame to preform this maintenance. Any suggestions?
The short story is Toyota claims it's a lifetime fluid. For most changing at 60k seems like the right answer.
As for changing/checking the fluid this thread is a great resource. It describes how-to and talks about WS fluid. Also within the thread are some great links that are worth following.
