"recently while driving to work at a traffic light as i rolled i heard my car start to accelerate and the check engine light came on. I began to observe, and found out that the gearbox does this when it is downshifted from 5th to 4th gear. of course I didn't hit the car in front several times."

What To Do Next

  1. 1
    Check for recalls on YOUR VIN

    Go to nhtsa.gov/recalls and enter your VIN. Free repairs if your vehicle is covered.

  2. 2
    Get a proper diagnosis

    A code alone doesn't tell you the exact failed part. A diagnostic at a shop ($50-$150) pinpoints the root cause before you spend money on parts.

  3. 3
    Compare repair quotes

    Get 2-3 quotes. Dealer vs independent shop prices often differ 30-50% for the same repair.
