TORQUE CONVERTER SHUDDER - SUPPLEMENT TO BULLETIN 82-I-227A ON 1982-83 THM 125-C TRANSMISSIONS
Some 1982 and 1983 THM 125-C transmissions may experience a torque converter shudder condition, immediately following the torque converter
engagement. Other suspected causes for this condition could be one or more of the items listed below. Inspect for the following conditions along with
those specified in bulletin 82-I-227A, file group 70, No. 68, dated November, 1982.
FIGURE 1 - TURBINE SHAFT SEAL GROOVES
1.
An incorrectly machined seal groove on the turbine shaft in the transmission. A step in the bottom corners of the seal groove (Fig. 1) will prevent
the turbine shaft seal from contacting the side wall of the groove, and will not seal. If this condition is found, replace the turbine shaft, and seals.
Follow service manual procedures for installing and sizing the seals.
