DTC P0781: 1-2 SHIFT (1-2 SHIFT VALVE)

DESCRIPTION

The 1-2 shift valve performs shifting to 1st gear and other gears. When shifting to 2nd and 4th gears is
impossible, or when the ECM directs the transmission to switch to 5th and 6th gear and the engine overruns
(clutch slips), this DTC is output.
