How it works
The block is dual-fit. One side fits early 6L80 and 6L90 transmissions that have the combined line fixture. Roll it 90 degrees and it fits the 6L80 transmission with the bypass block.
It connects to your flusher through quick connect fittings: 1/4 in NPT male on two ports and 3/8 NPT male on the other two.
