IPD's new web site is great! For flushing: http://www.ipdusa.com/products/4808/t7072-automatic-transmission-flush-hose-kit

Just get a clear plastic hose to fit over the end of the cars lower tranny hose and rout the drain to a gallon milk jug, marked at the 2quart level. Start the engine and pump out only 2 quarts. Add 2 quarts to the tranny dipstick hole and repeat until fluid is clean. Pumping out more than 2 quarts will produce bubbles and mess up the tranny pump. The entire operation takes 30 minutes or so, mostly waiting for the 3309 fluid added through the dipstick hole!

As for the B4 valve, doesn't look too hard. I would like to see pictures of someone lying on their back with their arms always in the wrong position :>) The tip for using a spare 10mm bolt looks great.

A lot of 3309 shouldn't come out, but let it drip/pour into a container to measure it.

Toyota sells 3309 fluid at a reasonable price, they use the same tranny. You will need at least 10 quarts for a good flush.
