Toyota T IV it's about 3 - 4 QTS Drain & Fill. I have a trans cooler also.

From the service manual. I have a 300, but the 400 is in the book as well.

I was thinking to go with Purple Power Max atf? or should I just use the Toyota genuine brand

The 300 and 400 use the same A650E transmission. 1.9 (I simply put in 2.0) quarts of Toyota T-IV will do it.

You can certainly go with a different brand if you wish, but I'm not sure if a drain and fill is the best idea, as you'd be mixing the two different fluids. Also, I'm not sure I'd attempt a tranny flush if it's never been done before and your car has higher mileage.

If you don't want to flush you could also just replace most of the fluid by simply disconnected the cooler line at the rad and let the car pump out the fluid. I think there is a DIY using this method somewhere here. Basically you disconnect the cooler line turn the car on for about 10 -15 seconds to let the car pump out tranny fluid into a bucket. Repeat this a few times and add fresh fluid whenever you have pumped out a quart or more. Keep doing this until you have replace about 12 quarts. Check to make sure you are the correct fluid level when you are done.

Isn't it true that the transmission will really use a FULL 7-8 qts if a total drain and fill is done?

I just drain 2 qts in a glass jar from the pan and replace with 2 new qts every oil change. I use Amsoil. I'd rather use a synthetic and from what I have researched the Toyota IV is a great fluid, it's just not synthetic.

this! except you should fill while the fluid is being pumped out. ive always done it this way. its a 2 person job though.

keep on filling till the fluid thats coming out changes to a nice clear/red. shut car off and top it off. run the car again, shift through gears, top it off. go for a drive and check the fluid level again. done
