LIGHT THROTTLE TORQUE CONVERTER CLUTCH SHUDDER ON ALL 1982-1983 THM 125C TRANSMISSION
Since the start of production, 1982, the THM 125-C transmission has had some changes in the auxiliary valve body cover. The changes were
implemented to eliminate a light throttle converter clutch shudder condition.
FIGURE 1 - CAST SLOT
The 1982 auxiliary valve body cover originally had a cast slot in it, (Figure #1) to exhaust oil from the converter clutch regulator valve.
FIGURE 2 - ORIFICED CUP PLUG
The auxiliary valve body cover was changed mid model year to that of having an orificed cup plug (Figure #2) in place of the cast slot. This orifice then
regulated the exhaust from the converter clutch regulator valve.
