OBD-II Code
P0759
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.

From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0759 is the intermittent version of the shift solenoid B electrical fault — the TCM saw the circuit fault appear and then disappear, usually thermal- or vibration-related.
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
- clear the code and drive the vehicle through a full thermal cycle while monitoring the solenoid command and feedback on the scan tool; wiggle-test the internal pass-through connector and external case connector with the engine running at idle in drive; check solenoid resistance both cold and hot — many failing solenoid windings only open when the copper is at full operating temperature; inspect the case connector pins for green corrosion or oil-soaked seal.
- Caveat: an intermittent code that only sets in hot weather or after extended highway driving is a thermal failure of either the solenoid winding or a marginal harness connection.
Vehicle-specific patterns1996-2002 GM trucks with the 4L60E set P0759 from intermittent case connector D corrosion that conducts when cold and opens when hot.
