Have you had a free battery test at the auto parts store? You can do that and get the codes too while you're there.

No I haven’t but I could put it on the charger and get it up to a full charge. Although I think it’s around 2 or 3 years old and I have never had a problem with the charging system

I just checked my fuse and it’s in good shape. I have never had electrical problems on a vehicle like this before. From the looks of the forum, I would say they are common for an HHR. Do I have all of this to look forward to on my 2006 Saturn Ion? They share the same drivetrain and electricals.

All what Electrical problems? The only thing I see that might be electrical is the power steering issue.
As stated before, post up the code numbers. Chances are you replaced the TCM for no reason.

Hard shifting is rarely ever the TCM. It is usually some seemingly unrelated fault that causes it. The computers put the TCM into open loop when some performance codes set.
I don't know of any relation to the power steering, it might be the cause of the shifting symptom. When we know the code we will know more.

Guess the OP isn’t coming back ?
Would have been nice to see those code #s so we could try and help.

So I’m not throwing any codes. From a stop it won’t shift until about 3500 rpm. Then from first to second around 4000 rpm. It doesn’t seem to shift in to high gear on the expressway either. I think I was riding around 4500 rpm’s on the E-Way. Slow acceleration too. Just bought it and they had to replace the left front wheel hub. And issues. Then they said they replaced the trans speed sensor. I’m guess the output speed sensor. What could this problem be? Bad TCM or VVT. 2.4 with 122,750 miles. 2006 LT

Have you considered a transmission shop?

You have a thread for your issues. Posting in other threads can lead to confusion for those trying to help.
