P0782

2-3 Shift Malfunction

DTC P0782, sometimes indicated as P078200 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the transmission (gearbox) causing 2-3 shift malfunction.

This code is set when the TCM detects a problem with the 2-3 shift solenoid or valve body.
Possible causes include a malfunctioning solenoid, a clogged or dirty valve body, or a problem with the transmission fluid.
If this code is set, the first thing to do is to check the transmission fluid level and condition. If the fluid is dirty or low, the transmission may need to be serviced.
If the fluid is clean and at the correct level, the next step is to test the solenoid and valve body. If they are found to be functioning correctly, the problem may be with the transmission programming or wiring.
