I have an '06 SS 2.4L automatic and the check engine light and t/c light is on. Hard shift from 1st to 2nd and it lags when I turn left. Bringing it in Monday to dealership (no warranty) to do a diagnostics and they are going to report it to GM. If anyone else has the same model same year with this problem pleas post it so I can print it out and send it to GM. I'm hoping they will do a recall so it can be fixed at no cost to us poor people. Thanks!
