2019 Chevrolet Impala Transmission Problems

Your transmission's torque converter started shuddering and the problem continued even after service. The shuddering didn't stop, and the entire transmission ultimately needed to be replaced.

Your car jerks when accelerating, and your key fob isn't being detected properly. Your radio works but seems stuck on a basic display screen. Your brakes feel rough when you apply them. These issues suggest problems with the engine, electrical system, and braking system that should be diagnosed together.

Your car displays a 'Shift to Park' message even though the transmission is already in Park, and the vehicle won't turn off. You've had to disconnect and reconnect the battery multiple times to shut down and restart the car. The dealer couldn't diagnose or fix the issue, and the manufacturer has been notified but hasn't provided a solution yet.

When it started raining, your check engine light and reduced engine power warning came on, and you couldn't accelerate past 35 mph. This suggests moisture may have affected your engine's sensors or ignition system during wet conditions. A mechanic will need to scan your engine computer for fault codes and inspect moisture-sensitive components.
