A/T - 200R4 Delayed Neutral To Reverse Engagement

SIL 89-34 (Nov)

SUBJECT: 1988-1989 THM

Delayed Neutral to Reverse Engagement
-- Revised Spacer Plates
New Spacer Plate I.D. Tab

DESIGN CHANGE:




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 identification letters are now visible after assembly.

All THM 200-4R models built after July 7, 1989, (Julian Date 188), were built using the revised spacer plate.

PART NUMBERS AND I.D.:




Part numbers and identification letters have not changed. Therefore, when servicing a THM 200-4R spacer plate, order the usual part number, and the replacement part will be the updated spacer plate.
