are you sure it is not 894? if so, then either your tranny fluid is low or dirty, or the trans itself is having an internal problem. with luck, you are just low on fluid, if so, check for leaks too.

Sounds like you should take it to a trany shop to have checked out. P0894 CHEVROLET - Torque Converter Clutch Fluid Diagram.... Possible causes - Low transmission fluid level - Dirty or contaminated fluid - Internal transmission failure.... When the Powertrain Control Module (PCM) detects excessive Torque Converter Clutch (TCC) slip when the TCC should be engage, then the trouble code P0894 is set. P0894 Chevrolet Description..... The Powertrain Control Module (PCM) monitors the difference between engine speed and transmission output speed. In D3 drive range with Torque Converter Clutch (TCC) engaged, the engine speed should closely match the transmission output speed. In D4 drive range, with the TCC engaged, the TCC slip speed should be -20 to +50 RPM.
