FIGURE 1
Beginning approximately in April of 1984, a slot was added to the case cover of the THM 125C transaxle. See Figure 1. The slot was added to the "drive
feed" oil circuit to allow transmission fluid to spray onto the drive link (chain) to provide additional lubrication. The slot is a "V" shaped groove cut into
the case cover in the area and direction as shown in Figure 1.. The slot is intentional and should not be considered as a damaged case cover.
