Can anyone tell me where I can refill automatic transmission fluid on a 2004 Toyota Sienna? I know where the drain plug is but I'm having a hard time figuring out where I can pour the new transmission fluid in. Thanks for any information.

why are you changing the trany fluid so soon?

Normally you don't need to change transmission fluid so soon ... but I had to...

In any case, I have figured it out. It's really simple, there is a dipstick for transmission fluid (it's similar to the dipstick for engine oil, and has an orange color), just pull that out and pour the transmission fluid in.

I really Hope that u put Type 4 trans fluid from Toyota in it becauseif u didn't read the dipstick your trans is toast!!!! y did u change so soon?

How often does Toyota recommend changing the transmission fluid?
