Codes in this family

This is the complete published member list for this guide. Each code retains its own page; shared diagnostic context does not mean that every member has the same test or repair.

What these codes mean

These forty-three entries compare shift-solenoid control and response faults while preserving eight reported condition types. P0750–P0774 retain the five-entry A–E groups: general or malfunction, performance or stuck off, stuck on, electrical and intermittent. The control-circuit groups P0972–P0974 A, P0975–P0977 B, P0978–P0980 C, P0981–P0983 D, P0984–P0986 E and P0997–P0999 F separately retain range/performance, low and high. The member list preserves every exact code and full title, including the unsuffixed P0760 designation.

The letter identifies the application’s solenoid designation. It does not establish a gear number, physical position, number of installed valves, universal binary gear-selection table or wear ranking. Identify the transmission, reporting controller, full code and any suffix before selecting a circuit or component. A vehicle can use different solenoid functions and driver arrangements from another vehicle with similar generic labels.

An electrical report and an unsatisfactory commanded response are different observations. Performance or stuck does not certify that wiring and electrical control are healthy. Electrical does not establish whether a terminal, internal harness, solenoid or controller has failed. Intermittent does not mean every test must be hot, the event was harmless or a connector is more likely than a winding. Use the actual monitor’s evidence rather than a rule based on the name.

Ford’s covered 2024–2025 summary separates open, short-to-ground, short-to-power, functionally failed-off, functionally failed-on and intermittent results. Its shift-solenoid table also shows full-code suffixes such as _13, _7F, _7E and _1F. The 8F24 table separately names shift solenoids, a torque-converter clutch solenoid and line-pressure control. Those examples do not provide universal terminal numbers, fault durations, gear assignments or test specifications.

Hyundai’s August 2023 bulletin 23-AT-003H-1 provides another bounded example for its listed eight-speed applications. Its P075300, P075800, P076300, P076800 and P077300 entries identify UD, 46, 37R, OD&LR and 28 respectively, separately from torque-converter and pressure-control solenoids. The bulletin includes preliminary data and wiring checks before its specified service sequence and conditional follow-up. That does not establish a universal replacement order, failed-part frequency or fitment for another transmission.

The control-circuit condition must remain distinct from a functional or general electrical result. Ford’s covered P0985/P0986 examples identify E short-to-ground and short-to-power while listing open and functionally stuck conditions separately. Mitsubishi’s cited 2019 RE/23C P0998/P0999 procedure instead names a low-clutch shift-solenoid short/open pair with its own operating prerequisites. Neither example assigns a universal F polarity, gear, component count, parked actuation proof or diagnostic rule to every transmission.

Save the full scan, status, available event information, recent work and the actual shifting complaint before clearing faults. More than one solenoid code can justify checking shared paths, but it does not prove one common conductor or rule out individual faults. One code does not independently certify shared supplies. Record warnings and symptoms without deliberately provoking slipping, binding, overheating, rough-road dropouts or a missing gear.

Have qualified personnel select the specified power state, access, circuit, command-response and hydraulic checks for the installed system. Do not use a generic guide to improvise live-harness movement, direct battery power, pressure tests, air tests or forced gear engagement. Any operating-condition testing must follow the matched professional procedure, with its specified equipment and precautions. A static resistance result, a click, a plausible scan value or a valve tested outside its assembly does not independently establish the whole diagnosis. Use the specified equipment and limits; do not substitute another solenoid’s reading.

Repair the demonstrated condition and complete the setup and verification required for that exact repair. There is no universal instruction to reset adaptations or perform a particular drive after every solenoid fault. Stop safely and arrange assessment or recovery for binding, serious slipping, unexpected engagement, loss of propulsion or applicable stop warnings. A restart, retained gear or cleared code does not establish safe continued operation. Ask for an itemized estimate covering the confirmed circuit, component or assembly and the actual access and setup.

Identify the circuit on your vehicle

Match the full DTC, reporting module, and any failure-type suffix to the service information for your exact year, make, model, engine, and equipment. An identifier alone does not establish installed hardware count, location, connector pinout, or a universal measurement.

Where the manufacturer publishes its own meaning for this code, that is the one to work from — it describes the actual component on your vehicle, which the generic definition cannot. Keep the generic description for what it is good for: it tells you which subject area the standard assigned the code to, which is useful context when the two appear to disagree. If they do disagree, follow the manufacturer.

About This Diagnostic Information

These guides provide general diagnostic context. A trouble code records a condition detected by a control module. It does not automatically identify a failed part, and the right diagnostic procedure can vary by vehicle.
