Chevrolet Express 3500 transmission failure with no reverse and oil loss after 90 miles, new transmission installed on Chevrolet Express 3500

Some Chevrolet Express 3500 owners report experiencing transmission issues, including a lack of reverse gear functionality and oil loss after driving only 90 miles. The absence of reverse gear may stem from problems such as worn-out gears or faulty sensors, complicating vehicle maneuverability. Additionally, oil loss shortly after driving could signal a leak in the transmission system, which requires immediate attention to avoid further damage. Owners may also face significant costs associated with installing a new transmission, making it crucial to ensure proper installation to prevent future complications. It is advisable for owners to consult a qualified mechanic or transmission specialist to diagnose and address these issues promptly, as timely repairs and maintenance can help maintain the vehicle's performance.
