Vehicle: 2018 Mitsubishi Outlander ES

Hey everyone,

I've got a 2018 Mitsubishi Outlander ES with about 75,000 miles on it, and I've started noticing a weird shudder or hesitation, especially when accelerating from a stop or at lower speeds (under 30 mph). It feels like the transmission is struggling to find the right ratio, and sometimes there's a slight jerk.

I'm wondering if this is a common problem with the Outlander's CVT, or if it's something I should be seriously concerned about. I've heard some things about CVT reliability, and I want to make sure I'm not ignoring a bigger issue. Has anyone else experienced this with their 2016-2026 Outlander?

Are there any known Technical Service Bulletins (TSBs) or recalls related to the CVT for this model year? I'm trying to figure out if this is just a characteristic of the transmission or if it's a sign of impending trouble. Any advice on what to check or ask my mechanic would be greatly appreciated. Thanks!

ClearTheCode admin answer:

It sounds like you're experiencing a common concern with Continuously Variable Transmissions (CVTs), often referred to as a 'shudder' or 'hesitation.' While CVTs operate differently from traditional automatics, these symptoms can indicate a few potential issues that warrant investigation, especially on your 2018 Mitsubishi Outlander.

  1. CVT Fluid Degradation: The most frequent cause of CVT shudder is degraded or incorrect transmission fluid. CVT fluid is highly specialized and critical for the belt/pulley system's friction and cooling. Over time or mileage, it can break down, leading to improper operation. Mitsubishi typically recommends CVT fluid changes at specific intervals (often around 30,000-60,000 miles, depending on driving conditions). If your fluid hasn't been changed, or if the wrong type was used, this could be the culprit.

  2. Valve Body Issues: The CVT's valve body controls fluid pressure and flow. Malfunctions or wear in this component can lead to inconsistent pressure, causing hesitation or shuddering during ratio changes.

  3. Software Calibration: Sometimes, the issue can be resolved with a software update for the Transmission Control Module (TCM). Mitsubishi, like other manufacturers, occasionally releases TSBs for re-calibrating the CVT's operating parameters to improve shift quality and address minor drivability concerns. It's worth checking with a Mitsubishi dealership if there are any outstanding TSBs for your specific VIN.

  4. Internal Component Wear: Less commonly, but more seriously, the shudder could indicate wear in the CVT's internal components, such as the belt or pulleys. This is usually accompanied by more severe symptoms or warning lights.

When to See a Shop:

YouYou should have your Outlander inspected by a qualified mechanic, preferably one with experience in CVTs, as soon as possible. They will typically:

  • Check for Diagnostic Trouble Codes (DTCs): Even without a check engine light, a scanner might reveal pending codes related to transmission performance, such as P0741 (Torque Converter Clutch Circuit Performance) or P0776 (Pressure Control Solenoid 'B' Performance), which can be associated with shuddering.
  • Inspect CVT Fluid: They will check the fluid level, condition, and color. If it's dark or smells burnt, a fluid and filter change (using genuine Mitsubishi CVT fluid) is often the first step.
  • Test Drive and Diagnosis: A professional will perform a diagnostic test drive to confirm the symptoms and may use specialized equipment to monitor CVT parameters in real-time.

Addressing this issue promptly can prevent more extensive and costly repairs down the line. Ensure any fluid changes use the correct Mitsubishi-specified CVT fluid.
