2016 MDX SH-AWD Transmission Jerking at Low Speeds - Any Ideas?

Vehicle: 2016 Acura MDX SH-AWD

Hey everyone, I'm experiencing some really frustrating transmission issues with my 2016 Acura MDX SH-AWD. When I'm driving at lower speeds, especially around 15-30 mph, the transmission feels like it's jerking or hesitating when shifting gears. It's not a smooth transition at all.

It's particularly noticeable when I'm slowing down and then accelerating again, or in stop-and-go traffic. Sometimes it feels like it's struggling to find the right gear. I've heard some chatter online about 9-speed transmission issues in these models, but I'm not sure if that's what I'm dealing with.

Has anyone else with a 2016 MDX SH-AWD experienced this? What was the fix? I'm worried it might be something serious.

ClearTheCode admin answer:

Transmission jerking or hesitation in your 2016 Acura MDX SH-AWD is a known concern for some owners, particularly with the ZF 9-speed automatic transmission. Here are potential causes and steps to consider:

  1. Transmission Fluid Condition: Over time, transmission fluid can degrade or become contaminated, leading to poor shifting performance. Low fluid levels can also cause issues.

    • Action: Check your transmission fluid level and condition. If it's dark or smells burnt, a fluid and filter change might be necessary. Ensure the correct Honda/Acura DW-1 or ZF LifeguardFluid 8 (depending on specific transmission variant) is used.

  2. Software Updates: Acura has released software updates for the 9-speed transmission to improve shift logic and smoothness. Your vehicle might be running an older calibration.

    • Action: Contact your Acura dealership to inquire about any outstanding transmission control module (TCM) software updates for your specific VIN.

  3. Solenoid Issues: The transmission uses solenoids to control fluid flow and engage/disengage gears. Faulty or sticking solenoids can cause erratic shifting.

    • Diagnostics: A diagnostic scan might reveal codes like P0700 (Transmission Control System Malfunction) or specific solenoid performance codes.

  4. Torque Converter Lock-Up Clutch: A failing torque converter lock-up clutch can cause shuddering or jerking, especially at specific speeds.

    • Diagnostics: Codes such as P0741 (Torque Converter Clutch Circuit Performance or Stuck Off) are often associated with this.

When to See a Shop: If a fluid change or software update doesn't resolve the issue, or if you're experiencing severe jerking, grinding noises, or the check engine light is on, it's crucial to have your MDX inspected by a qualified Acura technician immediately. Continued driving with a significant transmission issue can lead to more extensive and costly damage. They can perform advanced diagnostics, check for internal wear, and recommend appropriate repairs, which might range from solenoid replacement to a transmission overhaul or replacement in severe cases.
