2021 4 runner fluid replacement.

[tblt44]

Next weekend will be replacing fluids on my daughters 2021 4 runner.
Truck 90k on the clock.
It was bought with 38k, I assum no fluids ever changed.
For front and rear diffs I have Valvoline 75w 90
Transfer case I have Redline MT-LV
Transmission Im sticking with Toyota WS fluid from the dealer
Power steering Im using toyota ATF/power steering fluid from the dealer.
Break fluid Prestone Dot 3
Will try to get the truck in maint mode to get transmission temp correct.
Any good recommendations on a fluid transmissionfer pump to fill the Transmission?
Just did oil last weekend (Mobil 1 Extended Performance 0w20)that's not on the list next weekend.

Grease all your driveshafts while down there.
Think about a coolant change as well.
In general you have a good plan. The transfer case could also take 75w90, the ATF could have been Valvoline Maxlife.
For the ATF, you can go fancy monitoring temps if you want, or measure the exact fluid that came out, and put it the same back in. I've done this simple method three times on various Toyotas with success. I still don't get the temp monitoring procedure, seems excessive.

Yes I read many different options on the t.c and transmission but just playing it safe. Redline fluid wasn't much more than the valvoline anyways and it takes less than 2 it's. Have left over for next time

For atf fill I run 6’ of hose down from the hood into the trans, and get a funnel onto the hose. Drizzle it in from above. The 21 4R is probably pretty easy to do this on. My son has a 19 and the fill bolt has generous access

All went good
Filling the transmission with a 1/2 i.d. hose from under the hood and funnel went great.
Couldn't get the truck in maint mode to get transmission temp.
I went by feel of the fluid temp
Front diff a bit of a pain. Had to jack up drivers side to torque the fill bolt

90k all fluids not that bad. Bought truck at 42k. No ideavif ever changed
Diffs had metal flakes but not that bad.
Transfer case could have been left alone
Transmission dark but not black still reddish maroon
