I just replaced the K1 spring, what came out looks very different than the pics in the link (mine has missing parts). I have to drive it more to tell if it makes much difference.

There is an error in one of the steps of the walk through.

"Drop the pan and this is what you see. This is facing toward the rear of the car. The front of the transmission valve body has all these little plates. We'll be removing the one on the lower right of this picture and replacing some parts inside it with the K-1 spring kit......."

It should be "This is facing toward the FRONT of the car"
