When to change trans fluid

have a 4spd auto tranny. Iv heard either 100k miles or 60k miles and not sure which one to believe, so i figured the folks on the 4cyl forum would know best..

Also, what fluid would be best to use? I am sure there is a specific type that needs used.

 

You need to be more vehicle specific. Cant hurt to change it early if your at 60k id change it now

 

I change mine between 60-100k and thats km. Any vehicle. Depending on use ofcourse. High performance you'd do it more.

 

vehicle is a 2011 4cyl 4x4 4 spd auto.

 

Here is a general information link http://www.tacomaworld.com/forum/technical-chat/325531-aisn-warner-340-series-transmissions.html

 

manual says 10.8 qt of Toyota atf type t-IV. Is there any equivelant to that, or is that what I have to use. I havnt looked into it, but id assume Toyota asks an arm and a leg for their fluid

 

That may be the total capacity, but you will only get about 3-4 qt out by pulling the drain plug. The rest is up in the torque converter and other galleys and passages inside the transmission.

I changed mine at 60k miles, Toyota T-IV fluid is not that expensive, check Amazon. I drained & refilled then drove a couple thousand miles, repeated 2x. I figure about 80% of the fluid is fresh, good enough for me.
Toyota T-IV fluid.

 

Best time is between 8 and 9 AM.
