2017 RDX AWD Tech Transmission Jerks at Low Speeds

Vehicle: 2017 Acura RDX AWD Tech

I've noticed a strange issue with the transmission in my 2017 Acura RDX AWD Tech. When I'm driving at low speeds, particularly in stop-and-go traffic or when accelerating from a near stop, the transmission seems to hesitate and then sometimes jerks into gear. It's not a smooth transition at all.

It feels like it's struggling to decide which gear to be in, and then engages quite abruptly. This wasn't happening when I first got the car. I'm worried it might be a sign of a bigger problem.

The car has about 75,000 miles on it. Has anyone else experienced this with their RDX, especially the 2017 model? What could be causing this kind of transmission behavior?

ClearTheCode admin answer:

Transmission hesitation and jerking at low speeds can be concerning, but there are several common causes for this behavior in a 2017 Acura RDX. Here's a breakdown:

  1. Check Transmission Fluid: The first and most crucial step is to have a qualified technician check the transmission fluid level and condition. Low or old, degraded transmission fluid is a very common cause of shifting problems. Acura transmissions are particularly sensitive to fluid quality and level. Ensure the correct Acura-specific fluid (e.g., DW-1) is used if a top-off or change is needed.
  2. Software Update: The Transmission Control Module (TCM) in your RDX may require a software update. Dealerships often have updates that address known shifting quirks or improve shift logic for specific model years. This can often resolve minor hesitation issues.
  3. Adaptive Learning Reset: Over time, the TCM learns your driving style. Sometimes, resetting the TCM's adaptive learning values can help the transmission "relearn" optimal shift points. This procedure typically requires specialized diagnostic equipment and is best performed by a dealership or an independent shop with the right tools.

Causes: Low or degraded transmission fluid, Transmission Control Module (TCM) software issues, faulty solenoids within the transmission valve body, or internal wear on clutch packs.

When to see a shop: If checking the fluid and potential software updates do not resolve the issue, it could point to internal transmission components like solenoids or issues with the valve body. Ignoring these symptoms can lead to more severe and costly transmission damage. Seek professional diagnosis immediately to prevent further wear. While transmission issues don't always trigger a check engine light, a technician can check for pending diagnostic trouble codes (DTCs) related to the transmission system (e.g., P0700 series codes).
