I just did mine last weekend, just flushed 5 qts of oil from the trans and put back another 5 qts into the trans. I used RedLine trans fluid from ECSTUNING and replaced both plugs (drain and fill) as well as the 17 bolts in the trans oil pan. The trans now shifts smoother than before and I expect to do one flush more again until 100K. Thanks for this awesome DIY guide !
