A/T - New Servo Apply Pin for Improved Transmission Performance
FIGURE 2
Changes to the second servo apply pin eliminates the potential for seal damage during assembly. The changes were the elimination of the two-ring seals
as shown in Figure 2. Testing has verified that any potential leakage in this area will not affect transmission performance.
The new design second servo apply pin can be used on all 1982-88 THM 700-R4 transmissions.
NOTICE:
If a past design second servo apply pin is used on a THM 700-R4 transmission, seal rings must be installed.
