P0700 Code: Chevrolet Cruze (2016-2019) - Causes, Symptoms & Fixes

P0700 DIAGNOSTIC GUIDE for 2016-2019 CHEVROLET CRUZE

Data context

• OWNER COMPLAINTS: No NHTSA complaints found for this make/model/year/issue combination.
• OFFICIAL RECALLS: No recalls found in NHTSA database.
• No recalls found: "No recalls found in NHTSA database."

This guide uses general automotive diagnostic knowledge plus what is typically reported for P0700 on GM transmissions. It does not cite recalls or TSBs since none appear in the supplied data. Data limitations: there are no NHTSA complaints here for this exact combination, so real-world prevalence may differ locally. Treat P0700 as a trigger code that usually points toward a deeper transmission fault (often via a P07xx sibling code) rather than a stand-alone failure.

CODE MEANING AND SEVERITY

• Code meaning: P0700 = Transmission Control System Malfunction. It is a generic (class) code that indicates the transmission control module (TCM) has detected a fault in the transmission control system and has stored a fault memory. In many cases, P0700 is set alongside one or more specific P07xx codes (which identify the exact subsystem or component fault). On the Cruze, P0700 often points to the TCM, valve body, solenoids, or related electrical/ hydraulic control circuits.
• Severity: Moderate to high. P0700 by itself may not tell you the exact fault, but it commonly leads to symptoms like irregular shifting, limp mode, and/or warning lights. In many GM applications, the vehicle may enter a reduced-power/limp mode if the TCM detects a serious fault. Because P0700 usually accompanies a more specific P07xx code, diagnosing the exact cause promptly is important to avoid drivability issues or further transmission damage.

COMMON CAUSES ON CHEVROLET CRUZE

• Faulty or failing TCM (electrical or software-related), or poor communication between the TCM and PCM.
• Transmission fluid issues: low fluid level, burnt/dirty Dexron VI fluid, incorrect fluid specification, or fluid that has degraded with time.
• Wiring and connector problems: damaged, corroded, loose, or pinched wires to the transmission solenoids, valve body, or TCM; poor ground or power supply to the TCM.
• Shift solenoid or valve body defects: sticking solenoids, solenoid coil failure, or valve body wear causing improper line pressure or shift timing.
• Torque converter issues or friction components (clutch packs) wear.
• Transmission range sensor (gear selector) or related position sensing faults affecting proper gear selection.
• Electrical grounds or battery/charging system issues causing intermittent TCM operation.
• Transmission software calibration or reprogramming needs (not a physical part failure, but a software fault can store P0700 and other P07xx codes).

SYMPTOMS

• Intermittent or harsh/shaky shifting, or difficulty shifting into certain gears.
• Delayed engagement or slip during acceleration.
• Transmission may go into limp mode and stay in a limited gear (often 3rd or 4th) to protect the system.
• Check Engine Light and/or Transmission warning light on the dash.
• Reduced power/eco mode driving feel or erratic transmission behavior under load or during cruise.
• May or may not have audible noises tied to a hydraulic/solenoid issue.
  Note: P0700 is typically accompanied by other P07xx codes that point to the specific fault (e.g., solenoids, speed sensors, torque converter, etc.). If P0700 appears alone, a thorough scan for additional P07xx codes is essential.

DIAGNOSTIC STEPS

• Step 1: Confirm and scope

  • Retrieve all codes with a reliable OBD-II scanner capable of reading manufacturer-specific P07xx codes and the TCM data stream.
  • Note freeze-frame data, pending codes, and any active vs stored codes. Pay attention to accompanying P07xx codes (they drive the repair path).

• Step 2: Inspect basics

  • Check transmission fluid level and condition (hot, on level ground; Dexron VI for most GM automatics).
  • Look for signs of fluid contamination, burning odor, or metal shavings on the dipstick or in the pan.
  • Inspect the transmission dipstick area for leaks; check under the vehicle for fluid leaks.

• Step 3: Inspect electrical and connectors

  • Inspect the TCM and transmission connection harnesses for loose pins, corrosion, or damaged wires. Inspect grounds near the TCM and related control circuits.
  • Check battery voltage and charging system; weak/variable voltage can cause transmission control electronics to behave erratically.

• Step 4: Check for age-related or mechanical concerns

  • Gear selector/Transmission Range Sensor: ensure proper operation and alignment; misreads can trigger transmission faults.
  • Check for roughness or binding in shift linkage (if accessible) and any prior transmission service history.

• Step 5: Read P07xx-specific codes

  • Identify any P0715 (Input Speed Sensor) or P0720 (Output Speed Sensor) related faults, as speed sensor problems frequently drive P0700 behavior.
  • If P0740 (Torque Converter Clutch) or P0750-P0753 (Shift Solenoids A-D) or P0760-P0763 (another set of solenoids) or other P07xx codes appear, follow their targeted diagnostic paths.
  • Use live data for solenoid activity, line pressure (if your tool supports it), and gear position to verify proper operation.

• Step 6: Functional tests

  • Road test under various loads (accelerating, cruising, decelerating) to observe shift quality and locate when faults appear.
  • Check for repeated faults under a specific temperature range (cold/hot), as some solenoid/valve issues are temperature dependent.

• Step 7: Decide on repair path

  • If a P07xx code points to a sensor or wiring issue (e.g., speed sensor, solenoid circuit, worn connector), repair or replace the component, then recheck P0700.
  • If a mechanical fault is detected (valve body, clutches, torque converter, or valve body debris), address the component per the fault level (solenoid replacement, valve body cleaning or replacement, or more extensive transmission service).
  • If software is suspected, a dealer or shop with GM-compatible programming tools can reflash or update the TCM/PCM software; note that software changes can resolve some instances of P0700.

• Step 8: After repair verification

  • Clear codes, perform road test, and re-scan to ensure no new codes reappear.
  • Confirm proper shifting, no limp mode, and normal transmission temperature during operation.

RELATED CODES

• P07xx family codes are the direct relatives you should investigate when P0700 is present. Typical related codes include (examples; numbers may vary by model and year):
  • P0715 – Input/Turbine Speed Sensor Malfunction
  • P0720 – Output Speed Sensor Malfunction
  • P0740 – Torque Converter Clutch Circuit Malfunction
  • P0741 – Torque Converter Clutch Performance or Stuck Off
  • P0750 – Shift Solenoid A Malfunction
  • P0755 – Shift Solenoid B Malfunction
  • P0760 – Shift Solenoid C Malfunction
  • P0765 – Shift Solenoid D Malfunction
• Practical note: In many Cruze cases, P0700 co-occurs with P07xx codes that point to solenoids, speed sensors, or torque converter issues. Use the scanner’s live data to confirm which subsystem is failing before beginning major repairs.

DIY vs PROFESSIONAL

• Do-It-Yourself (DIY)
  • Pros: Lower parts cost; hands-on diagnosis and simple fluid changes are feasible with basic tools; learning experience.
  • Cons: Major transmission work (valve bodies, solenoids, TCM programming, or internal trans work) requires specialized tools, good lifting equipment, proper torque specs, and safety protocols. Risk of making a fault worse or missing a critical fault.
  • Suitable DIY tasks: Verifying codes, checking fluid level and condition, inspecting connectors for obvious damage, basic sensor checks, and performing a controlled transmission fluid change if you have the know-how and equipment.
• Professional
  • Pros: Access to factory-level scan tools, precise diagnostics, proper torque specs, software reprogramming, and warranties on parts and workmanship.
  • Cons: Higher labor cost; potential for longer wait times depending on shop availability.
• Recommendation: Start with a thorough diagnostic scan to identify the exact P07xx code(s) associated with P0700. If the issue involves sensors, solenoids, or a valve body that you can access with basic tools and knowledge, you may handle small repairs yourself. For valve body, TCM, or major hydraulic issues, rely on a qualified shop.

PREVENTION

• Regular transmission maintenance
  • Follow GM/vehicle manufacturer intervals for transmission fluid service (type Dexron VI where specified).
  • Use the correct grade and maintain proper fluid level; check fluid condition regularly, especially after long trips or heavy driving.
• Drive smart
  • Avoid aggressive starts and hard accelerations that heat the transmission.
  • Avoid towing heavy loads beyond the Cruze’s rated capacity, which can overwork the transmission.
• Keep electrical health strong
  • Ensure the battery and charging system are healthy; poor voltage can trigger transmission control faults.
  • Inspect and clean electrical connections to the TCM and trans sensors; fix corroded or loose connectors.
• Monitor and address symptoms early
  • If you notice shifting irregularities, erratic behavior, or warning lights, diagnose early to prevent further hydraulic or mechanical damage.
• Software updates
  • If a calibration/software issue is suspected, have dealer or a qualified shop check for available software updates or reprogramming for the TCM/PCM. While not cited from the data, software updates can resolve some P0700 scenarios in GM vehicles.
• Documentation
  • Maintain a record of any codes, symptoms, and repairs. This can help the mechanic diagnose quickly if the vehicle is moved between shops.

Bottom line

• P0700 in a 2016-2019 Chevrolet Cruze is a generic transmission control fault that usually requires identifying a specific P07xx fault code to pinpoint the root cause. The Cruze’s 6-speed automatic transmission relies on a combination of the TCM, solenoids, valve body, and speed sensors; faults in any of these areas can trigger P0700. With no NHTSA complaints or recalls in the provided data, this guide focuses on typical causes, symptoms, and repair paths seen in practice, while noting data limitations. When diagnosing P0700 on this model, expect to check for accompanying P07xx codes, inspect fluid and electrical connections, and consider solenoid/valve body issues or TCM software as common fault pathways. If you’re not comfortable with transmission work, seek a qualified technician to avoid inadvertently causing further damage.
