Yes, the MIL lit up as soon as it started revving high.

I don't remember the exact P07xx code number, but the HHR factory service manual said it was for "2-3 shift solenoid circuit high".

That's why I did the resistance test, which shows the problem is inside the transmission (probably the solenoid).

Oldblue, the solenoid kit that you linked to shows a pressure switch that looks a lot different than other sites show.

This ebay site seems to have a kit with the right switch:
Solenoid Kit

Buying the 5 parts separately at Rock Auto comes to about $118 (AC Delco parts except pressure switch which is Rostra), which is cheaper than the kit.

Its below zero (F) here so even with my barn heater it will be too cold to work on it now. Monday it starts to be above 40F so I will start then. I have to wait for the parts anyways.

Now that I have the lift and a pair of tall 2 ton jackstands (up to 7' high) it should be easier to tilt the transmission. The service manual says to remove the front cradle while keeping the engine/trans supported. I have an engine hoist so I can use that to hold everything up from above if needed.

Maybe I will take some pictures for a how-to since I don't see one anywhere.

Steve look at this. Also too, I'm envious you have a lift and garage.

Thanks, Cat Man.

So it looks like he dropped the subframe down about 6" on only the transmission side, keeping the other side connected. He doesn't mention lowering the transmission down so maybe after moving the subframe down there is enough access to the cover.

He mentions that the kit should have all new rubber seal pieces. I am getting a new valve body cover gasket from Rock Auto, but I don't see the other gaskets he pointed to inside the cover. Rock Auto does sell a Mahle valve body cover that does seem to include the large ring-shaped gasket inside the cover, but it's double the price of the AC Delco gasket ($17 vs $34) and doesn't include any other smaller gasket in the cover. Any ideas? Maybe all I need to replace is the main gasket on the cover.

The case cover seal is reusable
Dropping that side of the subframe drops the trans. If you notice right at the being the trans mounts are not disconnected from the subframe. Just watch what's up top as you drop it, lines, hoses ect.
And yes change the trans filter too.
Yes take pictures too.

Thanks for the video link, it helps a lot.

I am ordering the parts from Rock Auto now and will start as soon as the deep-freeze ends.

Any reason to buy the name brand Dexron VI fluid vs the store brand?

7 quarts of Valvoline is about $65.

With the 25% off coupon at advance auto, 7 quarts of CARQUEST fluid is about $43.

Why go cheap ? This isn't something you do often like changing the engine oil every 5-10k miles. $22 extra for a 1 time expense doesn't seem excessive to me.
(just curious. Do you use the cheap store brand when you change your engine oil ?)

Posting the two products by label would help.
If it meets or exceeds DextronsVI it is fine. Valvoline does. How about CarQuest ?
