P076B — Shift Solenoid H Performance/Stuck Off

P076B — Shift Solenoid H Performance/Stuck Off. A fault in the automatic transmission control. Short, gentle driving to a shop is usually possible. Typical causes: valve body wear, internal mechanical wear (clutches, torque converter), faulty transmission speed sensor.

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

How to diagnose with an OBD scanner

Read the code and freeze frame Connect an OBD2 scanner, confirm P076B is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the automatic transmission control for damage, corrosion, chafing or poor contact.
Subsystem check Command the shift solenoid h performance/ on and off with a scanner and watch the feedback signal; then remove and inspect the mechanism for sticking before replacing it.
Subsystem check Check transmission fluid level and condition — dark, burnt fluid points to internal wear.
Subsystem check Read transmission-specific codes and live data (solenoid states, input/output speed) with a capable scanner.
Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P076B does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P076B (parts and labor, USD, independent shop rates): Transmission rebuild or replacement: $2,500–$5,500; Replace a shift solenoid: $300–$800; Valve body repair or replacement: $700–$1,500; Transmission fluid service: $150–$350. Overall, fixing P076B usually costs between $150 and $5,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

How much does it cost to fix P076B?

Transmission rebuild or replacement — $2,500–$5,500; Replace a shift solenoid — $300–$800; Valve body repair or replacement — $700–$1,500; Transmission fluid service — $150–$350. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What is the most common cause of P076B?

The most common causes are: valve body wear, internal mechanical wear (clutches, torque converter), faulty transmission speed sensor.

What are the symptoms of P076B?

Drivers most often notice: no movement in severe cases, shuddering at highway speed, harsh or delayed shifting, slipping between gears.

What does OBD2 code P076B mean?

How do I diagnose P076B myself?

Start with a scan: confirm P076B, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the shift solenoid h performance/, and verify the suspect component against live data before buying parts.

When your vehicle's engine control unit detects that Shift Solenoid H is not responding correctly to commands, it stores OBD2 code P076B. This diagnostic trouble code falls within the powertrain category, specifically addressing automatic transmission operation. The transmission control module continuously monitors the performance of shift solenoids, comparing commanded states against actual feedback. When that feedback indicates the solenoid has failed to actuate or remains stuck in one position despite electronic commands to the contrary, P076B is triggered.

Modern automatic transmissions rely on a network of electronically controlled solenoids to manage fluid pressure and direct gear changes. Shift Solenoid H specifically assists with controlling transmission clutch apply and release sequences. The Powertrain Control Module (PCM) or Transmission Control Module (TCM) sends electrical signals to energize or de-energize this solenoid, expecting precise mechanical movement in return. Contamination inside the transmission valve body, worn solenoid components, or electrical circuit issues can prevent this expected movement from occurring. The module requires multiple fault occurrences under specific driving conditions before illuminating the Check Engine light—a safeguard against false triggers from single anomalous readings.

The freeze frame data captured alongside P076B proves invaluable during diagnosis. This snapshot records engine RPM, vehicle speed, coolant temperature, and load values at the exact moment the fault was detected. Technicians use this information to replicate the failure conditions during testing, dramatically improving the likelihood of catching an intermittent problem. Without addressing the underlying cause, continued driving allows internal transmission damage to accumulate, potentially transforming a straightforward solenoid replacement into a full transmission rebuild.

Symptoms of P076B

Vehicle fails to move in severe cases, particularly when shifting into gear
Noticeable shuddering or vibration during highway cruising speeds
Harsh engagement or delayed response when shifting between gears
Slippage where the engine revs without corresponding acceleration
Transmission locked in a single gear, triggering limp-home mode
Illumination of Check Engine light or transmission warning indicator
Unusual noises originating from the transmission during operation

Common Causes of P076B

Shift solenoid H mechanism contaminated or jammed by transmission debris, sludge, or corrosion byproducts
Weakened or broken return spring inside the solenoid assembly
Failed shift solenoid windings or internal electrical short/open condition
Welded relay contacts or damaged wiring creating permanent circuit engagement
Insufficient or severely degraded transmission fluid reducing hydraulic pressure
Wear or damage to the valve body bore where the solenoid seats
Associated mechanical wear including worn clutch plates or torque converter issues

Diagnosing P076B

Connect an OBD2 scanner and verify P076B is stored in the transmission or engine control module. Record all freeze frame data before clearing—these parameters guide your entire diagnostic approach.
Retrieve any related diagnostic trouble codes. Coexisting codes for pressure control, range sensor issues, or other solenoids often point toward the root cause rather than a secondary symptom.
Perform a thorough visual inspection of the transmission wiring harness and electrical connectors. Look for damaged insulation, corroded pins, loose connections, or evidence of heat damage that could interrupt solenoid operation.
Use a professional scan tool to command Shift Solenoid H on and off while monitoring the corresponding data PID. Compare actual solenoid state against commanded state, then physically inspect the solenoid if mechanical binding is suspected.
Check transmission fluid level and condition. Burnt, dark, or low fluid confirms the need for service and may indicate whether internal components have sustained heat damage.
Perform a road test matching the freeze frame conditions. Observe shift quality, note whether limp mode activates, and recheck for P076B return after clearing and retesting.

Repair Options and Costs

Addressing P076B typically follows a progression from least to most invasive intervention. Transmission fluid service and filter replacement represents the starting point, usually costing between $150 and $350. If the valve body requires attention—either due to solenoid seat wear or internal contamination—budget $700 to $1,500 for repair or replacement. Individual shift solenoid replacement typically runs $300 to $800 including parts and labor. When internal mechanical damage accompanies the solenoid failure, a transmission rebuild or complete replacement becomes necessary at $2,500 to $5,500.

How Much Does Fixing P076B Cost?

The total repair investment for P076B varies substantially depending on which component is ultimately responsible. Independent shop labor rates typically add $75 to $125 per hour. A straightforward solenoid replacement with transmission fluid service might total $400 to $900. Valve body work commonly reaches $800 to $1,600. Complete transmission overhaul or replacement represents the highest expense, often ranging from $2,500 to $5,500. An accurate diagnosis before purchasing parts remains essential—the majority of P076B cases resolve through fluid service or solenoid replacement rather than full transmission work.

Can You Drive with P076B?

P076B carries a caution severity classification. Short-distance travel to a repair facility may be acceptable if the transmission continues shifting without slippage or harsh engagements. However, extended highway driving with an active solenoid fault risks accelerating internal wear, potentially causing additional solenoids to fail or damaging clutch packs beyond repair. Limp mode, when engaged, protects the transmission by restricting operation to a single gear—but continued driving in this reduced state strains the transmission unnecessarily. Prioritize professional diagnosis within the first few days of noticing symptoms.
