I didn`t check the hyd pressure before I pulled it a part.
The input spline look fine no sigh of and distorison.
The piston gets pushed by hyd pressure in to the clutch pack either forward or backwards and those parts look fine.
The oil that came out kinda looks like AW46 but the customer has put other kinds of oil in there as he had leaks.
I`m going to mark all the hoses today so I can look in to the rear end and see what I can find back there.
