2016 TLX V6 SH-AWD 9-Speed Transmission Jerking and Hesitation

Vehicle: 2016 Acura TLX V6 SH-AWD

Hey everyone, I've got a 2016 Acura TLX V6 SH-AWD with about 75,000 miles. Lately, the 9-speed automatic transmission has been acting really weird. It feels like it's jerking quite noticeably when shifting, especially at lower speeds, and sometimes hesitates to engage a gear from a stop.

It's pretty unsettling and makes for a less smooth drive. I've heard some early 9-speed transmissions had issues. Has anyone else experienced this with their 2016 TLX? What did you do to fix it?

ClearTheCode admin answer:

Transmission issues like jerking and hesitation in the 2016 Acura TLX V6 are a known concern for some owners, particularly with the ZF 9-speed automatic transmission. This can be a complex issue, but here are common causes and steps:

  1. Software Updates: The most common initial fix involves a transmission software update. Acura released several updates to improve shift quality and address these symptoms. This often resolves minor jerking and hesitation.
  2. Transmission Fluid Service: Ensure your transmission fluid is at the correct level and has been serviced according to Acura's maintenance schedule. Old or low fluid can contribute to poor shifting.
  3. Transmission Mounts: Worn or damaged transmission mounts can cause excessive movement and lead to a feeling of jerking or harsh shifts.
  4. Internal Transmission Issues: In more severe cases, or if software updates and fluid service don't help, there might be internal wear or damage to the transmission components. This is less common but possible.

Diagnostics:

  • A common diagnostic trouble code (DTC) related to transmission issues is P0700 (Transmission Control System Malfunction), which indicates a general fault in the transmission control module (TCM). Further sub-codes will usually be present to pinpoint the exact issue.
  • A professional scan tool can read specific transmission-related codes and monitor live data to identify solenoid issues or clutch pack wear.

When to See a Shop:

  • You should see an Acura dealership or a reputable independent mechanic specializing in transmissions as soon as possible.
  • If the issue is worsening, accompanied by warning lights on the dash (like the 'Check Engine' light or 'Transmission System' warning), or if you notice any unusual noises, immediate attention is required.
  • They can perform the necessary software updates, conduct a thorough diagnostic, and recommend appropriate repairs, which could range from a simple fluid change to a transmission overhaul or replacement in rare cases.
