Only transmissions with at least three shift solenoids can set P0760, so it shows up on units such as Ford's 5R55 family, many Toyota and Mazda 5-speeds, and Chrysler's 41TE, 62TE and RFE transmissions, where it is used for the overdrive (OD) solenoid circuit. A classic GM 4L60E, with just two shift solenoids, won't log it. The TCM monitors the solenoid C circuit and sets the code when the voltage or current doesn't match its command, then usually disables the affected gears or falls back to limp mode. On some designs solenoid C is pulse-width modulated rather than simply on or off, which changes how it should be tested.
Can I keep driving? You can normally drive carefully to a shop. Without overdrive, highway rpm and fuel use go up; if the transmission is in limp mode, keep to low speeds and short distances.
How to read P0760
- P Powertrain
- 0 Generic (SAE)
- 7 Transmission
- 60 Specific fault
Symptoms
- No overdrive or no top gears – engine runs higher rpm on the highway
- Limp mode in a single gear on some transmissions
- Late or harsh 3-4 or 4-5 shifts
- Worse highway fuel economy
- Cruise control won't hold speed smoothly on hills because gears are missing
- Check engine light, sometimes an O/D OFF light flashing
Possible causes
Ranked by how often each cause is behind this code (editorial estimate).
- Solenoid C coil open or shorted
- Worn or failed solenoid pack on transmissions with combined solenoid assemblies
- Corroded or fluid-soaked case connector
- Broken or chafed wire in the solenoid C circuit
- TCM output driver failure
- Low battery or charging voltage
Diagnosis step by step
Confirm your transmission has a solenoid C
Look up the transmission code on the door label or in the service information and find what solenoid C does in it – overdrive, a specific clutch or a shift valve. This tells you which gears should be missing and whether it's on/off or PWM-controlled.
Tools: OBD-II scanner
Read freeze frame and other solenoid codes
Note speed, gear and temperature when P0760 set. A code that sets only at highway speed in top gear often means the circuit fails when the solenoid is energized for a long time and gets hot.
Tools: OBD-II scanner
Measure solenoid C at the case connector
Compare the resistance with spec and with the other solenoids of the same type. PWM solenoids usually read much lower resistance than on/off solenoids, so don't compare the two types with each other.
Tools: Multimeter
Check current draw or the waveform
For an on/off solenoid, an ammeter in series while it's commanded on should show a steady current close to battery voltage divided by coil resistance. For a PWM solenoid, a graphing meter or scope shows whether the TCM is producing a clean switching pattern.
Tools: Multimeter, OBD-II scanner
Inspect connector and harness
Unplug the case connector and look for fluid, green corrosion or spread terminals, then continuity-test the solenoid C wire to the TCM. Repair damaged sections with sealed splices.
Tools: Flashlight, Screwdriver, Multimeter
Replace the solenoid or pack
If the fault is inside the case, replace solenoid C or, on units with a combined pack, the complete solenoid assembly. Clear codes, relearn adaptives where required and road test through all gears.
Tools: Towels & shallow pan, Torque wrench, OBD-II scanner

Notes by brand
Chrysler
On Chrysler Town & Country and similar front-drive models with the 41TE or 62TE, P0760 is the overdrive (OD) solenoid circuit. The solenoid and pressure switch assembly is mounted outside the case, and a faulty assembly or its connector is a common cause; the transmission runs in 2nd gear limp mode while the fault is active.

Emissions / smog test impact
Will fail
P0760 turns on the check engine light, so the vehicle fails an OBD smog or emissions test until repaired and the readiness monitors have completed.
Frequently asked questions
Why doesn't my GM truck ever show P0760?
The GM 4L60E and 4L65E use only two on/off shift solenoids, A and B. Their extra solenoids for downshift and lockup control have other codes, so P0760 normally points to a transmission with three or more shift solenoids.
Which gear is lost with P0760?
Often overdrive or the upper gears, because solenoid C commonly controls the late shifts on 4- and 5-speed automatics. On Chrysler front-drive units the whole transmission goes into 2nd gear limp mode instead.
Can I replace just one solenoid in a solenoid pack?
On many transmissions the solenoids come only as a complete pack. Where single solenoids are sold, replacing only the failed one is fine if the others test good and the fluid is clean.
Will the problem get worse if I ignore it?
The electrical fault itself won't damage the gears, but driving for a long time without overdrive keeps rpm and temperature up, and limp mode strains the clutches that are in use.
