2009 Tacoma Automatic Tran fluid change and flush.

I’m going to be changing my automatic trans fluid on my 2009 4.0. What fluid do I need to use? And do I need to use any additives. If so what kind and how do I need to mix the additive into the fluid. Thanks guys

That will give you all you need to know. Used this method twice and it works flawlessly. Used Valvoline Maxlife and no issues. In fact, it seemed to work better than the WS fluid. Cheaper too!

 

So you simply remove the inlet and the outlet of the trans cooler and do it that way with a 3/8 clear hose i can get from any hardware store? I see anthony250f and a few others just use the inlet and outlet lines that come out through the front fascia to get to the trans cooler. I assume either one would work? really need to do this as im at 111k and i have no idea if the PO got his transmission fluid changed at 60k or they told him 100k. This way makes it so i dont have to mess with any plugs other than the check plug correct?

 

Yep 3/8 tubing and use a pump sprayer it's really easy.

I dropped the pan and replaced the pan gasket and the filter for piece of mind. The filter is a cheap part

Wait so if i buy a pump sprayer i just open up both hoses and pump new fluid in while having another hose in a giant jug. So eventually there is only new fluid? Am i forcing new fluid in to the transmission to push the old fluid out? Or am i letting it drain into the jug first with the truck running THEN i use the pump sprayer.

 

So basically to sum this up if i get a new filter, crush washers, some 3/8 hose and some 16ga wire with a couple graduated buckets i am good? Along with 15 wuarts of ATF. I have a small hand pump but where can i find this magnificient atf sprayer?

 

Ace is the place you can find said atf sprayer

 

Ace as in, the place with the helpful hardware folks? Roger that, got some time tomorrow to do some shopping for supplies. Thanks you sir.

 

Get something like this.

 

Just don't pump out more than 2 to 2 1/2 quarts at a time. Make sure to do the transmission fluid level procedure to make sure your transmission is at the proper level when you are done. I just did mine a couple of weeks ago and at that time Walmart was running free shipping on orders over $35. I bought 4 gallons at about 17.50 each and got free shipping on the whole lot.
