Transmission fluid swap

I drove about 20 miles between each drain and fill. My thermostat is also pinned open.

 

I thought there was a removable dip tube so you could get it all out?

 

It doesn't all come out. There is still at 2+ qts in the pan. I got almost 7qts total when I drained my pan and then removed it

 

Valvoline is good too. I did a complete exchange when I had my 15 Tacoma that used WS.

 

OEM Toyota WS is about 12.50 to 14.00 a quart. (theres your baseline)
AISIN, ATF0WS Arguably the only closest things to OEM. Paid on Rock 7.50 a quart.
(some people feel only oem for longevity, others like the instant savings of MaxLife (forum reviews can vary on they feel it works))
I went with AISIN, they are the manufacturer of the transmission. They know what it likes.

$25.92 bucks for Maxlife (Just checked Ama....) (1 gallon container)
30 for AISIN, ATF0WS (4 bottles @ 7.50 each) Rock does charge to ship.
54 for Toyota OEM WS (figure 13.50 per quart x 4)

What I dont trust with MaxLife is that it covers specs from all over the place.
Dexton 2,3.... Honda, Toyoto, Mercedes, BMW....
How can one lubricant cover all of them? Does it cure cancer too?
Dont get me wrong, stuck on the side of the road and need to fill it?
No problem. If at home doing maintenance? Not going to cheap out for only a few bucks.

 

What about undoing the transcooler line?

 

Way easier. Pin the t stat, pull a cooler line and turn the truck on to pump 2 or 3qts out. Dump same amount back in. Do that 3 or 4 times and you're set.

 

Holy moly. That looks like it’s been in for 200k miles.

 

Is there any data for those oils where one can see the difference?
My uneducated and ignorant understanding, it does not "cover" all of them, it is just the requirements for the ATF are so close to each other that by adding a couple of more additives they "cover" many manufacturer's requirements. Probably i'm wrong, but it is just my thought, so just putting it out.
BTW, my 2008 4runner uses this ATF for 244,000 miles and never complained, knock on the wood.

 

Grab a translator and have fun.

Did a 2.5gal pump and dump change. Oem fluid looked just like OPs. I'll probabky do another 6 quarts in 1 or 2k miles.

All I did was pull the lower hose from the t stat and pumped out 3qts, added 3, pump 3, add 3. Color definitely improved but still on the darker side.

 

Miles? What brand of fluid?

 

37k. Amsoil
