What Does the P0894 Buick Code Mean?

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.
