2010 hhr goes forward in all gears
You are correct this car has me crazy. As it is my god sons car and he has no money so I have taken on both the financial and mechanical responsibilities.
In P the vehicle is locked and cannot move but it feels like wants to. In R N D 1 L it will drive forward. I am in a heated shed so I drive forward then push it backwards. I have about 15 feet. Shut the car off. Then I shift the car into any position other than P and push the car to move it. If the car is in R D1L should I be able to move it easily? Thanks for your help we will get it figured out.

Just saw your post Blue. Thanks
I did check the TCM even placed a different on on from another car I have. Liked them so much I now own 3. It made no difference. All connections seem good. When is the side cover I left the PNP switch connected. I did take it off today however to check.
when I did the engine I put the pan cover back on so I was not pushing on the bottom. One of the solenoids had low reading so the original P0758 code was the issue. I think the next step will be to check the hydraulic pipe. Does that sound right?
Good afternoon. So last night I jacked it up and drained the ATF and removed the pan. The transmission lube pipe seemed fine. One of the o rings seemed wore so I had to find metric O rings. Got them correct size and replaced them all and put it back together.
I let it warm up and the ( drum roll here ) does the same thing as before. I again checked the linkage and the shifter, PNP switch. All look good.
Even disconnected the nut on the shift arm, had my son in the drivers seat, and moved it manually with a wrench through all the gears. Same results with forward motion in R N D 1 L.

(sorry for the big font copy and paste) Could these have anything to do with issues ? Thanks for your help.
I’m thinking possibly the pressure switch manifold might be faulty

I have not forgotten to post. Been to busy to work on the car. I believe it has something to do with items replaced. I am working on lowering and getting the transmission open through the wheel opening. I will post what I find.
This is what I found once opened. Looking at post and old blues last recommendation, this is as what I was hoping to find. I do not know how it came off. Most likely because I did not loosen the PNP switch on the top of the transmission. The area would have been tight and could have pushed it off. Will post again once it is driving.
Second picture shows the position where the shift connector is located. Top right of transmission under the cover. Thanks everyone!!
