Did you guys ever get it fixed? my 06 HHR with 177,XXX MILES locks act up when transmission begins to flutter from 2nd to 3rd gear and rpms go up to 5,000 after letting it sit for about an hour it goes back to normal it does it every now and then, the car was in the chevy body shop for about 2 months after being in a minor accident the hood and the radiator was replaced they had to jump start it when i picked it up its been 2 months since i picked it up and everything else is fine i need a few repairs of my own here and there but this problem accused right after i picked it up, i got the battery checked and auto zone said it is still good and i checked the rear 50 amp fuse by the battery as well, any idea?thanks

 

Hi Jesse, to the forums!!

Did AZ give you a printout of the battery test results?

What kind of "acting up" are we talking about?

Like was said before, the 2 systems really are not related, it's most likely an electrical problem. If the battery is the original, it is way past it's lifespan.

 

i uploaded a video of what it does please check it out thanks.

 

Is that the CEL or MIL light lit? What codes are there in the OBD II?
I’m thinking deadcell battery on its way south!

 

We don't charge by the word here; could you please tell us what your exact problem is?

I really doubt it is exactly the same as the OP, since he changed his in mid stream.

You have a check engine light, maybe find out why?

 

The locks and transmission act up when both problems are present, it has a hard time getting up to 40 mph the battery is not original and the check engine light is for a temperature sensor it needs to be replaced but the temperature gage is within normal range it never gets to even half, and no autozone didn’t give me a printout

 

First thing would be for you to have the CEL codes pulled and post them up here. Code numbers only. No descriptions since those can be misleading.
I got nothing from that short video.

FYI. There is no specific CEL for a temp sensor. There is one (P0128) for coolant temp too slow to reach operating temperature. 95% of the time that CEL is for a bad thermostat.
The analog temp gauge on the dash is not very accurate. Use the digital temp reading in the info center of the DIC. I'll bet your temps are too low.

Also. Posting which engine you have would help too.

 

I got the same code twice P0128 from Auto zone I also forgot to add that the cruise control doesn't work and the fuel gage fluctuates when these problems are present and car wouldn't go past 60 mph last night i will post a new video shortly my engine is 2.2L MFI DOHC

 

Oh, the A/C doesn't work either.

The p0128 means that the temp is not HIGH enough; the t-stat is stuck open.

New batteries can go bad.

There is no direct link between the door locks and the transmission.
