Vehicle: 2018 Mitsubishi Outlander SEL

Hey everyone,

I've got a 2018 Mitsubishi Outlander SEL with about 75,000 miles on it, and I'm starting to get really concerned about the transmission. Lately, when I'm accelerating, especially from a stop or at lower speeds, the car feels like it's shuddering or vibrating pretty badly. It's not a smooth acceleration at all.

Sometimes, it also feels like there's a delay or hesitation before the power kicks in, almost like the transmission is slipping. It's making me nervous, especially on the highway. I've kept up with all the regular maintenance, including fluid changes.

Has anyone else experienced this with their Outlander's CVT? What could be causing this, and what should I be looking for? Any advice would be greatly appreciated before I take it to the shop.

Sarah, the symptoms you're describing in your 2018 Mitsubishi Outlander SEL are classic indicators of potential issues with the Continuously Variable Transmission (CVT). CVT shuddering and hesitation are common complaints that require prompt attention.

Possible Causes:

  1. Degraded CVT Fluid: Even with regular changes, the fluid can break down over time, losing its lubricating and friction properties. This can lead to belt or pulley slippage, causing shuddering.
  2. Worn CVT Belt/Pulleys: The internal components of the CVT, specifically the steel belt and conical pulleys, can wear out. This wear can lead to improper engagement and slippage, manifesting as shuddering and hesitation.
  3. Torque Converter Issues: The torque converter can sometimes be a source of shuddering, especially if the lock-up clutch is failing or sticking.
  4. Transmission Control Module (TCM) Malfunction: A faulty TCM could be sending incorrect signals, affecting transmission operation.
  5. OBD Codes: While not always immediately present for mild shudder, a failing CVT can eventually trigger codes like P0700 (Transmission Control System Malfunction) or P0741 (Torque Converter Clutch Circuit Performance - Stuck Off). A professional scan is crucial.

When to See a Shop: You should schedule an appointment with a trusted mechanic or a Mitsubishi dealership immediately. Continuing to drive with a shuddering CVT can exacerbate the problem and lead to more extensive, costly repairs.

What to Expect at the Shop:

  1. Diagnostic Scan: They will connect an OBD-II scanner to check for any stored or pending transmission-related trouble codes.
  2. Fluid Inspection: The technician will check the CVT fluid level, condition, and color. They may also look for metallic particles, which indicate internal wear.
  3. Road Test: A road test will help the technician confirm the symptoms and assess transmission behavior under various driving conditions.
  4. Pressure Tests: Specialized equipment can measure internal transmission pressures to diagnose component wear.
  5. Internal Inspection (if necessary): In severe cases, the transmission may need to be removed and disassembled for a thorough inspection of the belt, pulleys, and other components.

Addressing this early can sometimes prevent a full transmission replacement, which is a significant expense. Ensure the shop has experience with Mitsubishi CVTs.
