Since around 20,000 miles, my 2018 Ford Fiesta SE has had a grinding noise after shifting at certain gears. I got the car serviced at that time. Now I'm at 70,000 miles and the noise has persisted, and has gotten worse. My transmission slipped at 0mph when I was accelerating, almost causing me to lose control of my car.
The car was driving at 68 MPH and approximately 2500 RPM started to loose speed down slight hill and rpms increased to 5,500 RPM. Let off the accelerator 3 seconds rpms decreased reapplied accelerator and operated properly.
Car shudders upon acceleration from standstill. Loses power severely going uphill. Engine/transmission shakes shudders engine races and quickly accelerates after loss of power then decreases again. When moving from stop car shudders makes a grinding noise and then slowly accelerates before decreasing RPM and then races again. *tr
