Dodge Grand Caravan acceleration issue due to suspected transmission failure at 70,000 miles on Dodge Grand Caravan

Some Dodge Grand Caravan owners report experiencing slow acceleration issues, which may be attributed to several factors beyond suspected transmission failure. Common causes include a clogged air filter that restricts airflow to the engine, a dirty mass air flow sensor affecting the air-fuel mixture, and a clogged fuel filter that limits fuel flow. Additionally, a malfunctioning fuel pump can disrupt fuel delivery, while a faulty oxygen sensor may impact engine performance by altering the air-fuel ratio. Owners also note that a dirty throttle body can hinder airflow, worn spark plugs can lead to misfiring, and a clogged catalytic converter can restrict exhaust flow. It is crucial for owners to seek a professional mechanic's diagnosis if transmission failure is suspected, as regular maintenance and timely repairs are essential for optimal performance of the Dodge Grand Caravan.
