Quick Answer
The P076F code means gear 7 incorrect ratio. It does not prove a seventh-gear gearwheel alone has failed. Save the scan, identify the exact architecture, and test the physical and electrical paths before selecting a repair.
What Does the P076F Code Mean?
P076F is standardized as Gear 7 Incorrect Ratio. It names a monitored result, not a guaranteed failed part. The reporting module, suffix and companion faults determine the relevant test branch.
P076F concerns a mismatch between the measured transmission ratio and the expected ratio in commanded seventh gear. The permitted slip and monitor conditions depend on the particular transmission.
The ratio is calculated from speed information and interpreted in the commanded operating state. If a speed signal is unreliable, the calculated result may be misleading. Preserve companion sensor and solenoid faults rather than clearing them first and leaving only the ratio code to justify a mechanical conclusion.
Hyundai TSB 24-AT-002H identifies P076F or P076F00 as an incorrect seventh-gear ratio. For its listed applications, page 3 directs the technician to address accompanying input/output-speed-sensor or solenoid codes before following a ratio-only branch. Its transmission-replacement conditions are not a universal rule for other makes or transmissions.
A repair estimate should distinguish a sensor or control-circuit correction from hydraulic work and internal mechanical repair. Ask which speed traces were validated, what gear was commanded, whether the ratio mismatch persisted with valid inputs, and what additional test isolated the apply circuit. Record fluid condition without treating color alone as a failure verdict. If a bulletin directs an assembly repair for the exact application, preserve its required checks rather than presenting the five-character code as the whole justification. Record the actual evidence, not a guessed failed gear.
Separate P076F from adjacent fault families
| Code | General description | Key distinction |
|---|---|---|
| P0730 | Incorrect gear ratio | Ratio classification without naming seventh gear. |
| P0734 | Gear 4 incorrect ratio | Different steady gear. |
| P0715 | Input/turbine speed sensor A circuit | Validate the signal used to calculate ratio. |
| P0720 | Output speed sensor circuit | Output-speed integrity is a prerequisite. |
Record the complete P076F description. The suffix, reporting module and companion faults can change the diagnostic path. Current manufacturer evidence governs when the queue wording conflicts.
P076F Symptoms and Likely Causes
P076F symptoms depend on fault status and the fallback strategy. Record what the driver and modules reported. A symptom list is not a parts list.
Save input/output speed and commanded gear at the event.
A protection strategy may prevent normal range selection.
Do not infer the failed friction element from the symptom alone.
Retrieve accompanying speed-sensor and solenoid codes before clearing.
Practical cause-checking order
- Connection evidence: A speed-sensor connection can distort the calculated ratio while the gearbox is mechanically sound.
- Electrical path: Input/output signal or solenoid circuit faults need their own diagnostic branch before ratio-only conclusions.
- Supporting condition: Incorrect fluid level/specification, leaks or pressure loss can affect clutch application.
- Component evidence: Internal friction or mechanical damage requires measured slip and transmission-specific evidence.
- Final decision branch: Calibration or controller work is justified only by exact current guidance and verified prerequisites.
Did P076F appear after recent transmission fluid, speed-sensor or control-system service? Recheck disturbed connectors, grounds, hoses, fluids, part numbers and setup steps for the seventh-gear ratio and slip evidence. Record battery and software history; a post-repair code does not prove the new part is defective.
How Serious Is P076F, and Can You Drive?
Arrange diagnosis promptly. When the warning is steady, operation remains normal and the owner's manual permits it, a short light-load trip to a repair facility may be reasonable. Avoid demanding use until the seventh-gear ratio and slip evidence is understood. P076F does not provide a universally safe distance.
Record temperature, load, speed, start state and recent service. Do not reproduce a severe symptom on public roads; another warning can make the situation more urgent.
Stop and arrange a tow if drive is lost, slipping is severe, engagement is unpredictable or the transmission overheats.
Stop for loss of drive, severe slipping, unpredictable engagement, overheating or burning odor. Do not recommend a DIY brake-torque/stall test or a high-speed reproduction run.
How to Diagnose P076F in the Right Order
-
Preserve seventh-gear speed and temperature data
Save commanded/actual gear, input and output speed, fluid temperature and the event record. Keep the original status and operating conditions so the next test answers the failure that actually occurred. If the event is intermittent, record what changes before reconnecting parts or cycling power.
-
Address speed-sensor and solenoid companion faults
Address companion input/output-speed-sensor or solenoid codes using the applicable service flow; Hyundai explicitly separates these from ratio-only cases. Confirm the exact component designation, connector view, equipment version and test state. A generic code description cannot supply a pin location, terminal assignment or pass/fail value for a different engine.
-
Verify fluid specification, level and leakage
Confirm correct fluid specification, level procedure and leakage evidence at the prescribed temperature; do not add generic fluid blindly. Check the suspected area without disturbing unrelated components. Photograph damage, note which circuits share a connection, and retest after a controlled correction so cause and effect remain traceable.
-
Test clutch application and slip with valid speed data
If speed signals are valid, evaluate clutch apply/pressure control and slip using the exact transmission procedure. Use the approved adapters and test instrument for the circuit. An unloaded continuity result can miss a fault that appears only during operation; an unsupported scan parameter is unavailable evidence, not a zero reading.
-
Investigate indicated hydraulic or mechanical damage
Inspect mechanical condition or debris only when indicated and with approved containment; a ratio result does not name the failed friction element. Compare evidence from the controller with the appropriate independent physical test. A request or learned label does not establish that the connected system can perform its function under the failed conditions.
-
Apply the supported repair and verify seventh gear
Apply Hyundai's transmission-replacement branch only to its listed applications and required conditions; verify stable seventh-gear operation afterward without provoking unsafe slip. Document what passed after the repair, including the original failure condition and any required monitor or learning state. Do not call a cleared warning a verified result when its enabling conditions have not occurred.
Specifications are vehicle-specific. There is no universal voltage, resistance, current, pressure, waveform, timing, temperature, percentage, learned value or drive cycle for P076F. Test state, connector location and system design change what a valid value means. Use only specifications for the exact VIN and do not transfer the OEM example in this article to another application.
P076F Repairs and Typical Costs
The correct P076F repair follows the failed test. Wiring, a physical repair, a proven component, software and controller work are different outcomes. Do not replace an assembly from the generic code alone.
After installation, recheck connector seating, harness clearance, fluid or mechanical setup and every required learn. Fluid level is meaningful only when checked by the exact transmission procedure, including its temperature and operating conditions. A generic top-up can create another problem or hide evidence of leakage. Ask for the recorded level, fluid specification and pressure or clutch-apply findings before authorizing internal work or replacing an assembly.
| Possible path | Current US estimate |
|---|---|
| Diagnosis and confirmation of seventh-gear ratio and slip evidence | VIN-specific quote |
| Verified connector, harness or supporting-system repair | VIN-specific quote |
| A component replacement supported by the failed test | VIN-specific quote |
| Required OEM setup and repeat-condition verification | VIN-specific quote |
There is no single national P076F repair price because these rows are alternative outcomes. Ask for an itemized estimate showing diagnostic time, parts, labor, fluids, service-information access and verification. Location, taxes, related damage and warranty eligibility change the total. Do not add the rows together or authorize an assembly without the supporting failed test.
Using iCarsoft CR Eagle P for P076F
On a supported vehicle, iCarsoft CR Eagle P can retrieve accessible module faults, save available freeze frame, display ECU-provided live data and create a diagnostic report. For P076F, preserve the original evidence and compare related modules before clearing an erasable record.

iCarsoft CR Eagle P
Review supported codes and relevant live data together. Confirm the exact VIN, controller access, PIDs and any requested active test with iCarsoft before purchase; generic product capabilities do not guarantee a P076F-specific function.
Check current CR Eagle P price and availabilityCheck CR Eagle P compatibility by VINThe official product page describes full-system diagnostics, available freeze frame and live data, and supported bidirectional tests and ECU coding; availability varies with the vehicle, ECU and software. Active-test and coding availability varies by vehicle and ECU and requires VIN confirmation. Follow OEM prerequisites and stop for abnormal operation.
Know the measurement boundary. The scanner reports information supplied by the vehicle. It does not directly prove terminal tension, circuit load capacity, leakage, pressure, temperature, mechanical travel or internal condition in the seventh-gear ratio and slip evidence. It also cannot replace the OEM-capable scan recording and transmission-specific fluid/pressure test equipment when the OEM procedure requires them. Interpret commanded and reported values alongside measured evidence.
Verify the P076F Repair
After repair, verify connectors, harness clearance, setup and controller supply. Save post-repair findings, then clear only erasable records through the approved procedure. Battery disconnection is not a repair.
Run the manufacturer's applicable verification conditions in a safe workshop or route. Compare the original operating state with current data for the seventh-gear ratio and slip evidence, and check current and pending faults in related modules. One clean start or idle period does not prove that every conditional monitor has completed.
If P076F returns, compare its suffix, status, failure order and operating conditions with the saved baseline before replacing another part. Revisit the failed branch and inspect anything disturbed. Keep mechanical repair, monitor completion, readiness and local inspection eligibility as separate outcomes.
A permanent P076F can remain immediately after a successful repair. If the vehicle stores it as a permanent DTC, a scan tool or battery disconnect cannot erase it. Once current and pending faults are absent, the OBD system removes the permanent record only after the applicable monitor reruns and passes.

P076F Frequently Asked Questions
Does P076F mean the named component is bad?
No. P076F describes gear 7 incorrect ratio, not a confirmed part. It also does not prove a seventh-gear gearwheel alone has failed. Test accessible wiring, supplies, grounds and supporting physical conditions, then follow the exact monitor tree. Replace a component only when its branch fails or an applicable OEM action specifically supports it.
What should I check first for P076F?
Save every module's codes and freeze frame before clearing. Confirm the full definition, suffix and VIN architecture. Then inspect recent transmission fluid, speed-sensor or control-system service, connectors and shared supplies. Those facts determine whether the next test needs the OEM-capable scan recording and transmission-specific fluid/pressure test equipment or a manufacturer-specific functional procedure.
Can I drive with the P076F code?
Only consider a short light-load trip when operation is normal and the owner's manual permits it. Stop if drive is lost, slipping is severe, engagement is unpredictable or the transmission overheats. The code number cannot establish a safe mileage allowance, and another warning can make the situation more urgent.
Why did P076F return after a part was replaced?
P076F can return after a replacement if inaccurate speed data, incorrect fluid level or specification, a control or hydraulic fault, or internal slip remains unresolved. Validate the speed signals first, then follow the specific pressure and clutch-apply tests. The Hyundai replacement branch applies only when its listed vehicle and diagnostic conditions match. Verify the repaired operation without repeatedly provoking severe slip.
What should a P076F repair estimate include?
A VIN-specific estimate is required because diagnosis may lead to wiring, a supporting physical repair, a verified component, software or a controller. Ask which failed test supports the quote and whether diagnosis, taxes, setup and post-repair verification are included.
Can CR Eagle P diagnose and clear P076F?
On a supported vehicle, CR Eagle P can organize available faults, freeze frame, live data and reports, and can clear erasable records after repair. Confirm exact ECU coverage. It cannot force-clear a permanent DTC or replace physical measurements for the seventh-gear ratio and slip evidence.
