2019 Camry SE: Rough Shifting and Hesitation at Low Speeds

0

Vehicle: 2019 Toyota Camry SE

I've been noticing some concerning transmission behavior in my 2019 Toyota Camry SE, which has the 8-speed automatic transmission. When driving at low speeds, especially in stop-and-go traffic, the car often hesitates before shifting, and then the shift itself can feel quite harsh or clunky.

It's most noticeable when accelerating from a near stop or when the transmission is downshifting. It doesn't happen all the time, but it's frequent enough to be a concern. I have about 65,000 miles on it.

Is this a common issue with the 8-speed automatic in the 2018-2020 Camry models? Could it be a software issue, or something more serious with the transmission itself? Any advice on what to tell the dealership?

ClearTheCode admin answer:

Rough shifting and hesitation in the 8-speed automatic transmission of your 2019 Toyota Camry SE is a concern that has been reported by some owners. While not universal, it's a known area of discussion for this transmission generation.

  1. Common Causes:

    • Transmission Software/Calibration: Often, these symptoms are related to the transmission control module (TCM) software calibration. Toyota, like other manufacturers, refines shift logic through software updates to improve smoothness and responsiveness.
    • Fluid Condition: While less likely at 65,000 miles if regularly serviced, old or low transmission fluid can contribute to rough shifts. However, Toyota's 8-speed is often considered 'sealed for life' by some, though many recommend fluid changes around 60k-100k miles for longevity.
    • Valve Body/Solenoid Issues: In some cases, issues with the transmission's valve body or solenoids, which control fluid flow for shifting, could cause inconsistent or harsh shifts.

  2. OBD Codes: A check engine light might not always accompany these symptoms, but if it does, potential codes could include:

    • P0700: Transmission Control System Malfunction (general code, indicates an issue in the TCM)
    • P0741: Torque Converter Clutch Circuit Performance or Stuck Off
    • P0751: Shift Solenoid 'A' Performance or Stuck Off

  3. When to See a Shop: You should schedule an appointment with a Toyota dealership or a reputable transmission specialist soon. Describe the symptoms precisely, noting when they occur (e.g., specific gears, temperatures, speeds).

  4. What the Shop Will Do:

    • Diagnostic Scan: They will scan for any stored trouble codes, even if the check engine light isn't on.
    • Check for TSBs: They will check for any Technical Service Bulletins (TSBs) related to transmission shifting for your specific model year and VIN. Toyota has released software updates for transmission behavior in various models.
    • Test Drive & Fluid Check: A technician will likely test drive the vehicle to confirm the symptoms and check the transmission fluid level and condition.
    • Software Update: If a TSB exists, they will perform a software reflash of the TCM, which often resolves these types of issues.

It's crucial to address this to prevent potential long-term wear on the transmission components.
