Thanks for the pdf instructions.
What I gained from that:
-Drain the ATF.
-Add ATF through overflow hole.
-Run vehicle, to completely flush torque converter and valve body with the new fluid (I assume). Twice.
-Drain fluid again.
-Tighten drain plug
-Refill final time through overflow hole.
-Fill until fluid wants to run back out of the overflow hole.
-Tighten overflow plug.
I've got a hand pump that threads onto quart and gallon bottles. I think that will fit the bill.
I did a drain and fill on my QX80. It’s definitely not as easy as the previous gen having the ATF filler tube accessible in the engine bay.
You’re going to need an ATF filler adapter. I bought mine from Amazon, part # CTA 7425. For less than $20, I also made my own DIY pressurized ATF filler pump, courtesy of YouTube. A hand pump is going to take much longer to get the fluid into that tiny filler hole because the diameter of the hoses on those fluid hand pumps are too big.
Don’t ignore the recommended temperature ranges either. It does affect how much the ATF drains when instructed too.
