2024 Integra A-Spec CVT feels like it's slipping or hesitating

Vehicle: 2024 Acura Integra A-Spec

Hi all,

I'm looking for some advice regarding my 2024 Acura Integra A-Spec. I've noticed recently that the CVT (Continuously Variable Transmission) feels like it's slipping or hesitating, especially when accelerating from a stop or at lower speeds. It's not a violent jerk, but more like a brief loss of power or a feeling that the transmission isn't engaging smoothly.

It's intermittent, but it's happening more frequently now. The car only has about 12,000 miles on it, so I wouldn't expect transmission issues this early. There are no warning lights on the dash, but the feeling is definitely concerning.

Has anyone else with a 2024 Integra or a similar Honda/Acura CVT experienced this? What could be the cause, and what steps should I take?

ClearTheCode admin answer:

Experiencing a feeling of slipping or hesitation from the CVT on your 2024 Acura Integra A-Spec at 12,000 miles is definitely a cause for concern, even without a Check Engine Light. CVTs are designed for smooth, seamless acceleration, so any perceived slipping indicates an issue. Here are potential causes:

  1. Low or Contaminated CVT Fluid:

    • The most common cause of CVT issues is improper fluid level or degraded fluid quality. Low fluid can prevent proper hydraulic pressure, leading to slipping. Contaminated or old fluid can reduce friction properties.
    • Acura CVTs require specific Honda HCF-2 fluid. Using incorrect fluid can cause severe damage.

  2. Worn Belt or Pulleys:

    • Inside the CVT, a steel belt runs between two variable-width pulleys. If these components are excessively worn, they may not maintain proper tension or contact, leading to slipping.

  3. Transmission Control Module (TCM) or Sensor Issues:

    • The TCM controls the CVT's operation based on various sensor inputs (vehicle speed, engine RPM, throttle position). A faulty sensor (e.g., speed sensor) or a glitch in the TCM's software can cause incorrect pulley ratios or engagement.
    • OBD codes related to CVT issues often start with P07xx (e.g., P0741 for Torque Converter Clutch Circuit Performance or Stuck Off).

  4. Software Glitches:

    • Sometimes, a software update for the TCM can resolve minor operational quirks or improve shift logic. This is less likely to cause true 'slipping' but can affect perceived smoothness.

  5. Torque Converter Issues:

    • While less common at low mileage, a malfunctioning torque converter can also contribute to a feeling of hesitation or slipping, especially during initial acceleration.

When to See a Shop: Given that this is a relatively new vehicle and transmission issues can escalate quickly, it's crucial to have your Integra inspected by an Acura dealership immediately. They will:

  • Check the CVT fluid level and condition.
  • Connect to the vehicle's diagnostic port to check for any stored or pending Diagnostic Trouble Codes (DTCs), even if no warning light is illuminated.
  • Perform a road test and monitor live data from the transmission to identify any anomalies in pulley ratios, pressures, or sensor readings.

Do not delay in getting this checked, as continued driving with a slipping CVT can lead to more significant and costly repairs.
