2017 Outlander Sport CVT acting weird, jerking and slipping

Vehicle: 2017 Mitsubishi Outlander Sport ES

Hey everyone, I'm having some serious issues with my 2017 Mitsubishi Outlander Sport ES. Lately, the CVT has been acting really strange. When I accelerate, especially from a stop or at lower speeds, it feels like it's jerking or slipping, and the RPMs will sometimes flare up without a corresponding increase in speed.

It's making me nervous about long drives. I've heard some things about Mitsubishi CVTs, but I'm not sure if this is normal wear and tear or something more serious. The car has about 85,000 miles on it.

Has anyone else experienced this with their Outlander Sport? Is there a known TSB or recall for this model year? I'm trying to figure out if this is something I can address with a fluid change or if I'm looking at a major transmission repair. Any advice would be greatly appreciated!

It sounds like you're experiencing classic symptoms of a Continuously Variable Transmission (CVT) issue in your 2017 Mitsubishi Outlander Sport. These transmissions are known for their smooth operation, but when they start to fail, jerking, slipping, and RPM flares are common indicators.

Here's what you should consider:

  1. Check for TSBs and Recalls: Mitsubishi has issued several Technical Service Bulletins (TSBs) related to CVT performance and fluid changes for various models and years. While not always a recall, a TSB can guide technicians on known issues and recommended fixes. Check with a Mitsubishi dealership or use your VIN on the NHTSA website to see if any apply to your specific vehicle.
  2. CVT Fluid Condition: A fluid change might help if the fluid is old or contaminated, but it's often a temporary fix if internal components are already worn. Mitsubishi CVTs require specific fluid (e.g., Mitsubishi DiaQueen CVT Fluid J4 or equivalent). Incorrect fluid or low fluid levels can cause significant problems. However, if the transmission is already slipping, a fluid change alone is unlikely to resolve the underlying mechanical wear.
  3. Common Causes:
    • Fluid Degradation: Over time, CVT fluid breaks down, losing its lubricating and friction properties, leading to slippage.
    • Internal Wear: Components like the push belt, pulleys, or valve body can wear out, causing inconsistent power transfer.
    • Software Glitches: Less common, but sometimes a software update for the transmission control module (TCM) can address minor shifting anomalies.
  4. When to See a Shop: You should get your vehicle inspected by a qualified mechanic specializing in transmissions, or a Mitsubishi dealership, as soon as possible. Continuing to drive with a slipping transmission can cause further damage and potentially leave you stranded. They can perform diagnostic scans (looking for codes like P0741 - Torque Converter Clutch Circuit Performance or P0730 - Incorrect Gear Ratio), check fluid pressure, and assess the internal health of the CVT. Be prepared for the possibility of a transmission rebuild or replacement, which can be a significant expense.
