Information on design changes incorporated into 200-4R transmission valve body spacer plates. The Lo/Reverse orifice in the spacer plate has been
enlarged to enhance Neutral to Reverse engagement performance (See Figure 1).
The revised spacer plates also include a new I.D. location. Previous spacer plates could not be identified while assembled in the transmission because the
identification letters were obscured by the valve body. A tab has been added at a different location (shown in Figure 1) and the identification letters are
now visible after assembly.
