2018 Outlander CVT hesitation and rough shifting from a stop

Vehicle: 2018 Mitsubishi Outlander SEL

My 2018 Mitsubishi Outlander SEL, with about 70,000 miles on it, has started acting really weird lately. When I accelerate from a complete stop, it often hesitates for a second or two before the power fully engages. Sometimes it even feels like it's 'slipping' or shifting roughly, which is strange for a CVT.

It's especially noticeable when I'm trying to go uphill or merge into traffic quickly. I'm really worried about the transmission, as I've heard CVTs can be expensive to fix. Has anyone else experienced this with their Outlander?

ClearTheCode admin answer:

  1. Check Transmission Fluid Level and Condition: For CVT transmissions, the fluid is absolutely critical. Low or degraded fluid can cause hesitation, slipping, and rough operation. While some CVTs are considered 'sealed for life,' it's always worth having a qualified technician check the fluid level and condition. If the fluid is dark, smells burnt, or has metal particles, it needs immediate attention and likely a fluid flush or replacement.
  2. Software Updates: Mitsubishi, like many manufacturers, frequently releases software updates for the Transmission Control Module (TCM) to address shifting anomalies, improve performance, and enhance durability. A Mitsubishi dealership can check if your 2018 Outlander SEL has any pending or recommended software updates that could resolve your issue.
  3. Common Causes: Beyond fluid issues, common causes for CVT hesitation include a worn torque converter, a faulty valve body within the transmission, or issues with transmission speed sensors sending incorrect data to the TCM.
  4. Diagnostic Trouble Codes (DTCs): If the problem is significant, your vehicle's computer might store diagnostic trouble codes. Common CVT-related codes to look for include:
    • P0741: Torque Converter Clutch Circuit Performance or Stuck Off.
    • P0700: Transmission Control System Malfunction (a general code often accompanied by more specific ones).
    • P0715: Input/Turbine Speed Sensor Circuit Malfunction.
  5. When to See a Shop: You should take your Outlander to a reputable mechanic or Mitsubishi dealership as soon as possible. Continuing to drive with a slipping or hesitating transmission can lead to more severe and costly damage, potentially requiring a full transmission replacement. Early diagnosis can often prevent minor issues from becoming major repairs. A professional can perform a diagnostic scan, check fluid pressures, and inspect internal components if necessary.
