Which valve bodies it fits

The lock-up valve and sleeve were used in early valve bodies, 1981 thru 1986. Later 700R4 valve bodies, 1986 to 1989, kept the valve bore but it was non-functional, and 1990 thru 1993 valve bodies were made without the bore. As long as the bore is in the valve body, the hydraulic package will apply, with no need to search through cores for the inner valve.
