What owners are reporting 1 most recent
Vehicle hesitation, transmission slippage at low speeds for up shifting and hard shifting. Pulled out of a parking lot onto a main road from stop and my vehicle would not upshift and sounded like I was in neutral and would not accelerate. I had a vehicle behind me that almost rear ended me, I pulled over and had to put the vehicle in park. Once restarted, it would shift again.
