I have the proper tubing to fit the return line from the radiator,and the 8 quarts of dinosaur blood Dextron for the flush. I also bought a pint of SeaFoam Tranny cleaner that is supposed to clean out the seals,bands, etc inside the tranny. It is added to the old fluid, allowed to circulate for 15 minutes, then the flush is done.
Am I endangering my AW tranny? Should I just skip the SeaFoam and just change the fluid by itself?
Any suggestions are welcome.

I think you should plan on using closer to the 12 quarts of trans fluid as recommended by the FAQ. I've just last week finished three AW70 flushes and, give or take, that's what it took to get reasonably clean fluid out the return lines. I probably could have used even more if I was a purist as two of the three cars were obviously overdue based on the initial outpouring.

I can't speak to Sea Foam TransTune. With or without an additive/cleaner you're going to want to do a thorough flush and will need the same amount of fluid. Many will spout the virtues of synthetic, but honestly, unless you're towing or otherwise overheating the trans, then I'd save the money and do the flushes more frequently. It's really no more difficult than doing an oil change once you've got the cheap little funnel, a length of vinyl tubing and spend a few minutes calibrating milk jugs.

While you're under the car, if there's any sign of weeping around the trans pan gasket then snug up the bolts (snug, not over-tightened). I was amazed at how loose a few of them were.

10 qts worked for me, but plan on having 12 on hand. If you're flushing with Dino fluid it's cheap enough to put extra in.

Red colored fluid started coming out at 8 qt stage. I figured that was good enough, especially since I had used SeaFoam Transmission flush additive to clean out the passages.
It has worked great so far as I do not get the shuddering and bucking coming to a stop that I used to get. I think the bands (clutches) were not disengaging due to the dirty fluid and now they are.
Good luck,

Thanks, Dave. I plan to get 4 more quarts for each car of 'dinosaur blood' Dextron tomorrow if it warms up here in South Texas. I don't want to do this flushing for maybe 25K miles down the road. Guess 12 qts will thoroughly clean out the old fluid.
Should I step on the brake then shift into drive during the flush to also clean the inner parts of the torque converter? Or does it not matter?
Thanks again,

Yes, run the trans through the gears, pausing for a few moments at each. Do this two or three times during the flush so can circulate cleaner fluid into the nether regions.

BTW Unless you're quite careful about measuring fluid drained, flushed, refilled, it's easy to overfill when you're done. Best to stop a little early on the final fill and take a measure. It's roughly one pint between max-min markings. If you do overfill then simply disconnect the return line again and run a little more out using the trans pump. The FAQ suggests opening the pan drain screw to do this, but in my opinion that's way too messy, you have to jack the car up again (it's easier to do the flush operation without the car raised), it's too easy to drain too much out, plus I don't like having a panic attack if the threads don't easily catch when I'm done. And speaking of mess, if you've ever wondered why people don't like to drop the trans pan to do a full drain and cleaning just remember that there's a lot of fluid sitting up in the gears and passageways that can take days to stop dripping. If you ever have to replace a kickdown cable you'll know what I'm talking about.

Thanks again, Dave:
I will do the shifting as you suggest. And overfilling is what happens to me frequently when I flush the 4 RWD Volvos I take care of for my family. I thought that reopening the flush line would be a better way to remove the little bit of overfill rather than the leaking pan method.
I'll let you know what happens as it will warm up to the 60's tomorrow. YEEHAAAW!
