The following conditions may occur on some of the subject vehicles if the torque converter clutch (TCC) solenoid screen (item 33) and/or O-ring seal
(item 68) is missing from the spacer plate or mispositioned in the spacer plate:
-
TCC applies during 1-2 shift.
-
TCC applies in 2nd gear during acceleration, then releases at steady throttle in 2nd gear.
-
TCC appears not to apply in 3rd gear because it already applies in 2nd gear.
-
TCC applies with wiring harness disconnected from transaxle.

NOTICE:
All 1984 THM 440-T4 transaxles and early 1985 models built prior to the Julian Dates listed below have the TCC solenoid screen in the
valve body and do not use an O-ring. The conditions listed above do not apply to these early transaxles.
