Code P0894 Buick Description

When the Engine Control Module (ECM) requests the neutral locked turbine feature, the Transmission Control Module (TCM) commands the 3rd, 5th, and reverse clutch and the 2-6 clutch to apply, which locks the turbine shaft. This provides a load to the engine and reduces the engine warm-up time. The Diagnostic Trouble Code (DTC) will be set when the TCM detects turbine speed greater than 50 RPM for 3 s. This condition must occur 3 times.
