TORQUE CONVERTER CLUTCH SHUDDER OR EARLY APPLY BETWEEN SERIAL B3C03D AND BCD12D 1983 THM 250C

ALL CHEVROLET DEALERS
Some Chevrolet built THM 250C or 350C transmissions between serial numbers 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.
