Consumer Description

Driving out of state. My 2021 Acadia with 41,172 miles. When pushing the gas to go there is slippage when trying to accelerate. MY car went automatically into neutral saying transmission and then not start. After a rest period it would start then repeat the same issue. In bumper to bumper traffic on I75. The most Terrifying & UNSAFE place to be at 75 to 80 mph. We happened to be driving up on construction and slow down traffic. When the car stalled. Towed it to a transmission place because of code. They replaced the DTR1 PCM.
