Hurst2001 , to answer your question I choose Mobil synthetic but Castrol, and Valvoline have similar fluids.

CA Blue HHR

Is there a filter to change?

Yes, there is a filter.

DexRon VI specification is a Synthetic.

I just purchased a "transmission filter kit" from Advance for around $20. It's got a filter and a pan gasket.

My estimation of re using an after market gasket has changed, that thing is thin with no ribs or metal inner lining. I will probably re use the OE gasket.

I did re use the OE gasket. The 2011 had 2 donut magnets on the pan instead of the 1 square magnet on my 2008. I noticed a fair asmount of gray sludge in the pan, comments? The ATF was still "red-ish" after 96,000 miles, but closer to black.

I do notice a difference in shifting, but that may be because I put almost a quart more in than came out. I have added a ATF cooler since I got the car, and seems to have a small leak on the R side axle seal.

Where can I find instructions on changing transmission fluid in the 5-speed manual HHR 2.0L
Turbo?

Why would you replace it?

Simply put: drain it, refill it.

Assuming you have the GETRAG , close to the same on MU3

drain the bottom hole. fill at the top hole. Big arrow toward front of CAR.
