Diagnostic Steps

  1. Scan for Error Codes

    • Use an OBD-II scanner to check for any stored transmission-related fault codes.
    • Note any codes that may provide insight into the issue.

  2. Check Fluid Levels and Condition

    • Park the vehicle on a level surface and engage the parking brake.
    • With the engine running, check the transmission dipstick (if equipped) for fluid level and condition (should be bright red and clear).
    • Inspect for any burnt smell or metal shavings in the fluid.

  3. Inspect Transmission Software

    • Verify if the vehicle's software is up to date. Manufacturers often release updates to improve transmission performance.
    • Check with an Acura dealer for any service bulletins related to transmission issues.

  4. Test Transmission Components

    • Use a multimeter to test the transmission range sensor and solenoids to ensure proper operation.
    • Check for any visible damage or leaks in the transmission casing.
