P0894 is an OBD-II diagnostic trouble code meaning “Transmission Component Slipping.” This generic transmission code means the PCM/TCM detected that a rotating component inside the transmission is slipping, by comparing input and output speeds and finding more difference than there should be for the commanded gear. Slippage indicates clutches or bands are not holding properly, which can quickly worsen and damage the transmission through overheating and accelerated wear. It often comes with rough or flaring shifts, reduced power, and overheating, and should be addressed promptly. This code is most commonly reported on 2007-2016 GMC Yukon XL, with repair costs ranging from $150 to $3,000.
