Rodney Flush (Fluid Exchange) for 2016 4Runner

[BILT4ME]

Does anyone know or has anyone done a Rodney Flush on a 2016 (5th Gen) 4Runner?
What fluid to use? Toyota WS?
Change the filter as well?

How do you determine the correct amount of fluid during this process?

1GR- family engine and related trans? I forget the model number of the auto tranny that goes with that engine family. As I recall, the 4R and FJC of that era all used the same drive train and front end.

If so, then yeah, I have done the Rodney flush on several FJC’s, including my own.

I used Toyota WS on mine, but Amsoil also makes a good full-synthetic WS substitute.

I didn’t drop the pan and change the filter on mine, but it’s probably due for one now.

The fill/level check procedure is complicated and annoying but doable. It’s supposed to be done in a fairly narrow fluid temperature window. You can short (jump) two pins on the OBDII plug and get an indicator on your instrument cluster for that. When it’s the right temp, then you use the overflow port on the bottom of the pan to get the right fluid level, while filling it from the fill plug on the side of the tranny.

Yes, it's the 1GR. Not sure on the transmission model yet. It's all new to me and we don't have a full FSM yet, but @Malleus hooked me up, I just haven't read through it yet.

Its like starting over for me, but I'll bet better on the other side. Main thing is teaching my son the resources and what to do.

We'll look it over and formulate a plan.
Thank you!

You’re welcome!

Son helping will be good; it’s way easier with two people. One can be pouring ATF in a fill hose from above while the other is holding and watching the flushing line underneath the truck, and making sure the fill hose stays put on the fill hole.

It’s in the factory service manual, which pins to jump in the OBDII port, and how to read the (odometer?) readout in the instrument cluster.
