Hi Mari. Thanks for sending your question to us today. In most cases, a lack of acceleration like you’re describing is due to the transmission slipping. Sometimes this is due to dirty transmission fluid while in other cases, it’s a sign of a faulty torque converter or inner seal damage. I think the best way to move forward is to have a professional mechanic complete a hard to accelerate inspection, so they can determine what repairs are needed.
