OBD-II Code
P0773
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$300–$2,400
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0773 is the electrical fault on shift solenoid E circuit — this is typically a fifth or sixth solenoid in transmissions with more than 4 forward gears, or the TCC-related solenoid on some platforms.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

Cheapest-first ladder
- identify which physical solenoid is the E designation for this transmission (it varies by platform); measure the resistance at the case connector against the FSM spec for that specific solenoid; inspect the internal pass-through harness; check TCM driver voltage with the connector unplugged.
- Caveat: shift solenoid lettering is not standardized across manufacturers, so always cross-reference the code definition against the specific FSM before ordering parts.
