Shift solenoid C circuit fault.
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 work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
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.

P0760 indicates an electrical fault in the Shift Solenoid C circuit (3-4 shift on many transmissions, lockup or 2-3 on others depending on application). The PCM detects an open, short to power, or short to ground in the solenoid driver circuit and typically commands a limp-home state with fixed gear engagement.
Start with the cheapest checks
scan for companion codes (P0765 often appears with internal harness failure), inspect the external transmission connector for fluid wicking up the wires (a classic sign of failed internal case connector seal), then back-probe the solenoid feed at the case connector with the key on and measure resistance to the solenoid body. Typical resistance specs are 19 to 31 ohms on GM 4L60E/4L65E shift solenoids at room temperature, 9 to 16 ohms on Ford 4R75W/4R75E units, and 11 to 15 ohms on Chrysler 45RFE/545RFE solenoid block units. Anything reading infinite (open), under 5 ohms (shorted), or wildly out of spec when hot points to the solenoid; an in-spec reading with the code still setting shifts suspicion to the harness, internal case connector, or TCM driver. Caveat: ATF-contaminated external harnesses can wick fluid all the way to the TCM and destroy the driver, so always inspect and seal the case connector before installing a new solenoid or you will burn the replacement.

- 2003to 2007 Chevrolet Silverado/Tahoe with 4L60E/4L65E commonly fail the 1-2 and 3-4 shift solenoids together due to debris from a worn 3-4 clutch pack contaminating the solenoid screens, and GM TSB 04-07-30-009 covers updated solenoid kits.
- 2004to 2008 Ford F-150 with 4R75W trips P0760 from the internal wiring harness chafing on the case rib near the solenoid body, requiring a new internal harness rather than just the solenoid.
- 2005to 2010 Honda Odyssey with the 5-speed (BGRA/BYBA) sets P0760 from the linear shift solenoid B failing electrically, and Honda issued multiple service news bulletins for the updated linear solenoid assembly.
- 2007to 2012 Nissan Altima with the RE0F10A CVT will flag P0760 equivalents when the step motor or pressure solenoid valve body assembly fails, almost always requiring full valve body replacement.
Estimated repair$180 to $850.

P0760 — frequently asked
What does a P0760 code mean?
Shift solenoid C circuit fault.
What causes a P0760 code?
Common causes: Failed solenoid; Wiring.
What are the symptoms of a P0760 code?
Typical symptoms: Harsh shifts.
Is it safe to drive with a P0760 code?
Not for long. Driving on this one risks further damage. Get it to a shop rather than carrying on with it. Estimated repair: $200-$800.
How do I diagnose a P0760 code?
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. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
