VERY IMPORTANT!!! Easy, but important! when you install your TC, slide it in, then pull it out about 1/8 inch and turn it slightly and push back in until it goes all the way in. There will be about an inch or so between the teeth of the TC and the edge of the bell housing of the tranny. If this isn't seated all the way, you'll break the pump when you tighten the tranny to the block.
