Vehicle: 2017 Acura MDX Technology

My 2017 Acura MDX Technology is acting up. Lately, the transmission feels really clunky, especially when shifting from 2nd to 3rd gear. There's a noticeable hesitation, and sometimes it feels like it's slamming into gear. It's really unsettling and I'm worried about long-term damage.

I've also noticed a slight delay when accelerating from a stop. No warning lights are on yet, but the driving experience has definitely changed for the worse. Has anyone else experienced this with their MDX? What could be causing this?

  1. Check Transmission Fluid: Start by checking your transmission fluid level and condition. Low or dirty fluid can cause significant shifting problems. Ensure it's at the correct level when the engine is warm, and note if it looks dark or smells burnt.
  2. Software Update: Acura has issued software updates for transmission control modules (TCM) in some MDX models that can address shifting irregularities. A visit to an Acura dealership might be necessary to see if your vehicle qualifies for such an update.
  3. Pressure Switches/Solenoids: Faulty transmission pressure switches or solenoids are common culprits for jerky shifts. These components regulate fluid flow and pressure within the transmission.
  4. OBD-II Scan: Even without a check engine light, a professional OBD-II scan can reveal pending codes (like P0700 - Transmission Control System Malfunction or P0705 - Transmission Range Sensor Circuit Malfunction) that indicate specific issues within the transmission system.
  5. When to See a Shop: If checking the fluid doesn't resolve the issue, or if you notice any warning lights (especially the "D" light flashing), it's crucial to have your MDX inspected by a qualified Acura technician immediately. Continued driving with a slipping or harshly shifting transmission can lead to more severe and costly damage. They can perform a diagnostic test, check for software updates, and pinpoint the exact component causing the problem.
