Good Day All,

My 07 Tahoe approx 89,000 miles. When I am in idle position the service stabilitrak and service trantion control message comes up and resets. When I start moving my car jumps from 1st gear into second gear and then it runs fine until I am in the idle position again.

My mechanic says I need to replace my lifters 3K job. I have cleaned the lifter valves and am still having the same problem. I am really trying to get this sorted out without having to paying a lot of money.

I also had it to the dealer here in The Bahamas and they don't have a clue.

Thanks All

 

there will be fault codes set in the computer modules....the ebcm and possibly the pcm and tcm . have them read and post them.

 

My 07 Tahoe LT is having the same issue along with a plethora of "breakdowns" lately. I have spent way too much money on it already and nothing is fixed!!!!!! I am totally exhausted and frustrated right now. I can't even at all......
