Condition




The load signal (TQ) from the engine control module ECM provides the transmission control module (TCM) with information about the torque being delivered by the engine. This signal also provides information about engine speed (rpm), and whether the engine is idling or if fuel is shut-off. Diagnostic trouble code (DTC) AT-134 is posted if the transmission control module (TCM) does not register an incoming load signal when the transmission speed sensor signal indicates that input shaft speed is above 600 rpm after the torque converter.

Substitute value
The transmission control module (TCM) "Emergency mode I" program has been initiated.
