Yep whole thing...then they charge you a core charge to get the old back they outsource building so you don't have an autozone screw up rebuilding them.
When i was looking for mine...I actually found a phone number to make contact with the trans compnay that rebuilds them...they know what they are doing. They even used the really high dollar red goop sealant stuff. I had an awesome shop install it and they said they were really impressed with the tranny...they said the goop stuff is like 80 dollars a bottle.
