Jerks- Auto Transmission Shifting Gear- RPM Drop
I bought my used 2007 Cobalt Lt (97K miles) 6 months back. Drove it for 7k miles. Recently i noticed the car Jerks when the Automatic Transmission shifts in RPM Tachometer (1st & 2nd gear). Also, the car makes a Thud (Shake) when i shift gear from P to D.
I thought it was a Cylinder Misfire caused due to bad O2 sensor and changed it
now i guess its a Transmission related issue.
I moved to USA a year ago from India for my Masters Degree.,so I have very less idea about cars.
