I'm 2 changes into the 3 change program to switch over to Amsoil. The car is just about to hit 70000 miles and the first drain looked like oil out of the motor. After the 2nd it was reddish black, you could at least tell it was transmission fluid.
The car drove just fine before, but now you never feel it shift, you can hear it a feel the RPMs change, but the shift itself is almost unnoticeable. I hate to be the guy pimpin Amsoil, but in this case I think it's the best option since the price is almost the same. There's a little more labor involved, but after the first drain you figure it out and the next 2 times together are probably quicker.
I got the 2.5 gal jug with $10 for a 6 month membership. I think it worked out to less than $110 with shipping, hard to say exactly I got a lot of other things and overall the $10 deal saved me about $50 total when I worked it out both ways.
I've been getting 80oz out with each change I may have enough to do 4 changes, I'll have to wait until my O rings come in to see if there is enough left after the 3rd for another one.
