Governor modification kit.
The Shift Point Package will service governors in the 700R4, 400,
350, 350C, 250 and 250C.
The kit includes 6 weights and 6 springs to offer a wide range of adjustments.

Useful for 700-R4, 200-4R's and other units working without computers and needing help getting lock-up in and out at the proper time. Unlike the GM vacuum switch, this switch allows the vacuum trigger point to be adjusted between 1 to 6 inches of vacuum. This switch can also be wired-in to be normally open or closed.

The lock up valve and sleeve was used in early valve bodies 81 thru 86. The later valve bodies, 86 thru 89, kept the valve bore, but were non-functional. 90 thru 93 valve bodies were produced without the valve bore. As long as the bore is in the valve body, the hydraulic package will apply.  * This kit includes 5 different springs giving 5 select lock up speed choices. * This kit includes all valves necessary.   * It allows non-electrical operation of lock up. * No more searching through cores looking for the inner valve.
