I have been running Valvoline MaxLife ATF in my 2010 FJ Cruiser since I purchased new. Replaced about 3.2 qts per year just draining pan and refilling. Just put back same amount as you drain out.

 

Yeah I have bought it from Walmart too, but you have to get the order total over $50 to get free shipping. For some reason they don't stock it in the stores around here. Sometimes Autozone has it $2 off, which makes it $17.99.... and for some reason Advance is the highest at $25.99

And you're right, I use a Sherwin Williams measure bucket and I get exactly 104oz out, so I put exactly that much back in.

 

Same thing here in Colorado. Used to stock it at WalMart and now they only stock their SuperTech generic stuff and Castrol Trans Fluid. So I buy online. Walmart changed their free shipping threshold to $35...so two 1 gal bottles will get you free shipping. Direct to my door and I pay lower tax since I am in unincorporated area and only have to pay state/county tax when delivered to my door rather than buying in the store.

 

I bought some sort of WS compatible stuff from Walmart. I spent 10 minutes reading the back of all the bottles they had there. Feels the same as the stuff Toyota put in it before and I saved a ton of money.

Also, if you happen to have a scan-gauge, you can program it to read your transmission temp and double check the temperature is ok without having to fiddle with shortcutting the OBDII #4 &#13 (I believe thats correct) and then putting the truck into AT Fluid check mode.

 

I use my ultragauge to check the fluid level, there are two temp sensors in the transmission. You want to use the pan temp and check the fluid between 97°F and 115°F. I verified that the temps are correct when I did a drain and fill in April.
