Spn-876 compressor clutch circuit

P0740 is one of the most common transmission trouble codes. It means that the Odyssey 's computer has detected that there is an issue with the torque converter clutch (TCC) solenoid circuit. The TCC "locks" the drivetrain, which allows for a true mechanical connection between the transmission and the engine. In effect, this allows an ...
