Torque Converter Clutch Solenoid: All Technical Service Bulletins
Torque Converter Clutch - Shudder or Early Apply
Model Year 1983
Bulletin No. 83-193
File in Group 70
Number 35
Date Oct. '83
SUBJECT:
Torque Converter Clutch Shudder or Early Apply
MODELS AFFECTED:
All 1983 LeSabres equipped with THM 250C (M31) Transmissions
Some 1983 LeSabres equipped with THM 250C (M31) transmissions with serial numbers between B3C03D and BCD12D, may experience a condition
of torque converter clutch shudder or early apply.
If this condition is encountered, the cause may be a restriction in the T.C.C. solenoid assembly which prevents it from exhausting. This causes the
solenoid to function as though it were applied at all times. Therefore, the converter clutch will apply whenever the 2-3 shift is made and will not release
until the transmission is downshifted to a lower gear.
To correct the condition, the T.C.C. solenoid must be replaced.
