A518/46RH transgo TFOD-HD2 shift kit install

7791C19B-757D-4B35-A616-9B54C8A809EB.jpeg I’m planning the 46RH swap to replace my 727 in the fall and have decided to do the transgo tfod-hd2 valve body shift kit. I haven’t seen a thread on this shift improvement kit so decided to give it a documented effort for those of us with limited experience with transmissions and valve bodies.
So here goes.
I referenced the instruction booklet that comes with the kit as well as the trans go YouTube video as they go hand in hand and the video, although not perfect, gives very good instruction.
