P0760
SeriousShift Solenoid C Malfunction
Usually drivable short-term, often minus some gears — which means higher RPM and more heat than normal, especially at highway speed. Keep trips modest, skip the towing, and get it tested soon. If the fluid turns out dark or burnt, move faster: the fluid is likely why the solenoid quit.
What this code means
P0760 flags a malfunction in shift solenoid C — the third member of the solenoid set the transmission uses, in combination, to select gears. The story is the same as its A and B siblings (P0750, P0755) with a different circuit: the computer commands C and either the circuit tests faulty or the transmission's response says the solenoid didn't act. Because gear assignments are unique to each transmission design, which shifts go wrong varies — typically it's the upper gears or specific shift pairs, showing up as held gears, skipped shifts, high cruise RPM, or limp mode. The two failure families are electrical (coil, connector, harness) and hydraulic sticking (debris and varnish — check the fluid first). On many transmissions solenoid C shares a pan or valve-body location with its siblings, so labor quotes track the same access question.
Symptoms you might notice
- Missing or skipped shifts, often in the upper gears
- High RPM at cruising speed (no top gear)
- Harsh or mistimed shifts
- Limp mode
- Check-engine light
What it costs to fix
Typical range: $80–$600 · about ~0.5–3 hrs of labor
| If the cause is… | Part | Labor |
|---|---|---|
| Shift solenoid C | $30–$150 | ~0.5–3 hrs |
| Wiring / connector repair | $10–$120 | ~0.5–1.5 hrs |
Identical economics to the other shift solenoids: an inexpensive part whose bill is set by whether it's pan-accessible (short job) or behind the valve body (hours). If several solenoids are aging, doing the set while access is open often beats repeat labor later.

Frequently asked
Does the solenoid letter (A, B, C) tell me how serious it is?
No — the letters just index different circuits, and seriousness is about the failure type, not the letter. Any of them can be a cheap coil failure or a sticky plunger. What the letter does is tell the technician exactly which circuit to test and which shifts should be affected on your transmission's logic chart.
Why am I missing my top gears specifically?
On many (not all) transmissions, solenoid C participates in the upper-gear combinations, so a dead C leaves the lower gears working and the top ones unreachable — hence high RPM at cruise. Your transmission's shift table is the authority; the symptom pattern plus the code usually agree with it.
Can I just keep driving without top gear?
For days, not months. The car functions, but sustained high-RPM cruising raises fluid temperature and burns extra fuel, and whatever stuck this solenoid (often contaminated fluid) is still circulating. It's a finish-the-week code, not a live-with-it-all-year code.
What's the realistic best case and worst case?
Best case: dirty fluid, a service frees the solenoid, done cheap. Middle: one dead solenoid, cheap part, labor per access. Worst realistic case: sticking valve body needing cleaning or replacement. A rebuild only enters the picture if the pan shows real friction debris — a solenoid code alone doesn't put you there.
