by replacing the forward clutch with the new forward clutch assembly.
The neutral to reverse package can be used to service a 1985 or 1986 (before Julian date 189) THM 125C transaxle exhibiting a harsh reverse
engagement by replacing the lo and reverse clutch assembly with the new lo and reverse housing assembly, and new lo and reverse clutch pack assembly.
(The lo and reverse clutch pack assembly contains both wave plates, the steel and composition-faced plates, and the correct selective backing plate.)
1986 and/or 1987 Model Year:
When servicing the forward and/or lo and reverse clutch assemblies on a 1986 (after Julian date 184) or 1987 THM 125C transaxle, it is important to
select the correct backing plate. The backing plate selection effects piston travel and shift feel.
FIGURE 2 - FORWARD CLUTCH BACKING PLATE SELECTION
To check the forward clutch backing plate selection, apply approximately 10 lbs. of pressure on the backing plate and check the gap between the backing
plate and snap ring. If the gap is larger than 1.49 mm (.052"), use the next thicker backing plate, and if smaller than 0.67 mm (.023"), use the next thinner
backing plate. Refer to Figure 2 for alternate backing plate selections.
The new lo and reverse clutch pack assembly (wave, steel, compositioned-faced, and selective backing plate) is serviced as an assembly only.
