Jerks in slow speed
Trailblazer was launched in India now. My friend owns one. It has this problem of jerking both in drive mode and reverse mode when moving in traffic in slow speeds. It has a 6 speed automatic transmission gear box and 2.8L duramax engine. I am unable to find out whether the problem is in the engine or transmission box or in the differential or in the propeller shaft. Can you please suggest some solution to this problem?
