FIGURE 1 - TRANSAXLE IDENTIFICATION INFORMATION:
A 1982-1984 THM 125C transaxle may exhibit a harsh Park/Neutral to Drive engagement.. Refer to Figure 1 for transaxle identification information.
FIGURE 2 - FORWARD CLUTCH ASSEMBLY:
At the start of production (SOP) 1985, all THM 125C transaxles were built with a new forward clutch assembly. This change eliminated the check ball in the forward clutch housing (Figure 2, Item 624--arrow indicates check ball location) and provided bleed orifices in the forward clutch piston assembly (Figure 2, Item 629).
The new forward clutch housing (Part Number 8653977) is used to service all 1982-1984 THM 125C models. The new forward clutch piston and seal package (Part Number 8637973) must be installed when replacing a forward clutch housing.
