How much ATF oil for flush?

[INDYMAC]

I have a 2000 Toyota Tundra 4X4 and want to take my own oil in for an ATF flush at the dealer. Does anyone know how much I'll need to buy? The manual only states 2.1 qts for a drain and fill. I'm guessing it will take 12-14 qts.
I'm trying to get away from Toyota's Dexron III because my torque converter has always been inconsistent on lock-up...sometimes smooth, occasionally hard. I currently have 130K miles on the transmission. No towing, but occasional heavy loads. I'm looking at the following upgrades:
AMSOIL ATD Torque-Drive
Schaeffer's #204SAT All Trans Supreme
LE 1150 Trans-All EHP
They all look like they will do the trick on paper. Does anyone have any experience with them?

When using our BG machine a work it is 16 quarts no matter what.

Extra won't hurt anything but the wallet. Actually give it more time to get more old oil out as it is not a direct 1:1 new versus old oil equation.

for that flush it yourself if your gonna bring your own oil.

I did my truck on the street with 2 buckets. I have no dipstick on the transmission. I used the hard lines on my transmission for fill and draining with some extra 3/8id hose from home depot. Worked great and saved lots of money except like $12for hose and buckets.

One hose into a full bucket of new ATF for delivery, and one hose into an empty bucket for waste?
When you started the engine, how long did you let it run, and were there any procedures to be especially aware of?

You will not get suction out of the intake transmission line. I used a hand pump. I ran the truck for about 2 or 3 quarts shut her down and then pumped in the same amount (if you have dipstick fill that way). I had a total of 15 quarts of oil for transmission and that is with 3 extra to make sure I flushed it all out.If you used something like this WEB

you can do it all simultaneously. Also if you have a transmission cooler your going to allow the oil to exit out of the cooler into waste bucket and then fill via transmission return line. This way you flush cooler too. Worked great for me. Fluid is nice and red and the old one was super dark brown. This method works great, because you flush out your torque converter also. When your done just check your level via dipstick or like transmission with service port under transmission(pain)

Thanks for the suggestions guys. I ordered 4 gallons of AMSOIL ATD Torque Drive and will try to do the flush, or have Toyota do it for $87.50. They thought it was a good idea to get the Toyota Dex III out of there and the AMSOIL in too, even if I just had their flush done 10K miles ago.
