Intermediate clutch piston done with new seals and bushing.

Old bushing had a groove worn into it.

Pressing in the new bushing. I was slightly off center though the oil hole wasn't covered at all. I suppose this is OK?

Wondering if i could find a manual shift tcase from a 1500hd or 2500 with a 4l80 and the driveshafts would fit?? And not have to worry about swapping i out on my tcase. Also wondering how hard it would be to get trans crossmember from truck with 4l80 and make it work, time for research!!!
