P0772 indicates that the vehicle's computer has detected that shift solenoid E is mechanically stuck in either an open or closed position. This prevents the transmission from properly regulating hydraulic pressure, which inhibits its ability to execute gear changes as commanded.
The solenoid itself has mechanically seized or has an internal electrical short, preventing it from moving or regulating fluid flow.
Burnt fluid or debris inside the transmission can clog the solenoid valve, causing it to stick open or closed.
Corroded, chafed, or disconnected wiring and connectors in the solenoid circuit can cause an open or short circuit.
Debris or wear inside the transmission valve body can physically restrict the movement of the valve controlled by the solenoid.
A failed PCM driver that controls the solenoid ground or voltage, though this is a very rare cause for this specific code.
It is not recommended. The vehicle will likely enter Limp Mode, restricting speed and gear selection, which can be unsafe. Continuing to drive can also cause severe internal transmission damage.
No. In most cases, this is resolved by replacing a faulty shift solenoid, changing the fluid, or repairing a wiring issue. A complete transmission replacement is rarely necessary.
Rarely. Drivers are sometimes told to replace the PCM, but this is almost always incorrect. A stuck solenoid code is overwhelmingly caused by a physical failure of the solenoid, dirty fluid, or a wiring issue. PCM failure is highly uncommon for this code.
It is an electromechanical valve inside the automatic transmission that opens and closes to direct hydraulic fluid to specific clutch packs, enabling the transmission to shift into the gears assigned to that specific solenoid.
