I own a 2018 Ford F-150 with 56,000 miles, and I have been experiencing serious and unpredictable transmission issues. These problems first started around 48,000 miles, but at the time, I assumed it was normal behavior. However, the issues have progressively worsened, and by 55,000 miles, a wrench warning light started appearing intermittently. Symptoms: â¢While driving at highway speeds, the transmission unexpectedly drops from 10th gear to 1st gear, causing a sudden and severe deceleration. â¢The gear shifts are jerky, unpredictable, and rough, making it difficult to maintain control of the vehicle. â¢The wrench warning light appears occasionally but disappears quickly, making diagnosis difficult. â¢No diagnostic trouble codes (D DTCs) are stored or retrieved when scanned at multiple repair shops. â¢The issue happens intermittently, making it challenging to replicate on demand. â¢Started noticing issues at 48k miles, but they became significantly worse around 50k miles when the wrench light began appearing. â¢I called Ford to reset the radio/computer software, after hearing it might help, but it did not resolve the issue. â¢The unpredictable transmission behavior causes severe anxiety while driving, as I never know when it will happen again. Attempts to Fix: â¢I have taken my truck to multiple repair shops and Ford dealerships, but since no codes are present, they have been unable to diagnose or fix the issue. â¢Mechanics have checked for transmission recalls or software updates, but no clear solution has been provided. â¢I contacted Ford for a radio/computer software reset, hoping it might help, but this did not fix the problem. Safety Concerns: â¢The abrupt downshifting poses a serious safety hazard to myself and other drivers on the road, especially at high speeds. â¢There is an increased risk of accidents due to sudden deceleration and loss of control. â¢The problem occurs without warning, making it difficult to predict or prevent.
