Does anyone know if you can add LL or deep reduction to an eaton 9 or 10 speed? We have mostly 8LL and one 9LL in our trucks and the low hole is very useful for what we do. My thought was that if the conversion is do-able, we would convert the others if the tranny ever has to come out for other reasons, or if it doesn't have to come out maybe do it anyway. I was thinking it could be as simple as adding a back box, plumbing a few airlines and shortening the drive shaft? Or maybe not?
