My car is running A1. I bought it used and now is 80 000 miles. It's a 2007 LS 2.2L and I don't think it ever has a transmission fluid change or flush. Should I proceed with either or is it risky and I should leave the transmission fluid as it is? Thanks
According to the OM , it’s lifetime transmission fluid, no need to change it unless you drive in severe conditions, like heavy traffic using you HHR as a taxi or delivery vehicle.
That being said, it’s up to you, I change fluid and filter at 100,000 miles. Along with spark plugs, coolant
I know that you or your neighbor has an Owner Manual. If still not, look at my sig.
I do have the OM.
I need to double check with actual owners. I heard stories from people who changed or flushed their transmisson fluid and things went downhill from there. And I doubt the OM was written for a 15 years old HHR.
Many shops advise against flush and fill on transmission with over 100,000 miles. But they also recommend flushing the electronic power steering fluid.
I changed my tranny fluid, filter and the spark plugs when I bought my HHR.
I did not do a 'flush'.
That was in 2016 at 108k.
Getting ready to do it again this year at 190k.
This may be overkill but it's how I do things.
So, again, it’s up to you the owner, simply drop the transmission pan drain the fluid, replace the filter ( AC Delco)
gently wipe the gasket off and the gasket surfaces, wipe out the pan , reinstall the gasket and pan torque the bolts to 89 inch/lbs . Fill with transmission fluid, Here’s the chart of capacities
No matter what the parts guy or shop guy says use Dexron VI , a 2006 may have come with Dex III but GM changed recommendation to Dex VI for all. It is synthetic designed for long life.
