Problems/Service/RepairsIf you have a problem with your HHR, want a tip on repairing or performing a particular service to you HHR here is the place to post!
When my wife gave my 2008 HHR back I noticed that overdrive was not kicking in, it came up with 2 codes PO751 shift solenoid A, wiring and plug looked good so I pulled the side cover of and a pin with a tiny spring fell out. It's a 2.4 & 4 speed automatic with 185k. It shifts fine 1st thru 3rd. I can't figure out where and what the pin belongs to. There is a tiny spring that goes on it, not sure if it's from an old broken solenoid??? Please help, Thanks 5/16 x 1 1/6 long with a tiny nipple that the spring goes on
You probably don't notice that 1st is gone also. That looks like the innards of a solenoid. My guess is somebody has been there before and broke or misplaced the spring clip (304). And the head (305) is hanging around somewhere.
If you already have the side cover off you should be able to replace it. It is called "1-2 shift solenoid".

That's just what I was thinking and hoping, I believe it was previously repaired and the pieces were left behind. None of the solenoids are burnt or falling apart. Thanks a bunch!
I found a big kit on Amazon for $70 which includes:1*Shift Solenoid A (1-2),1*Shift Solenoid B (3-4),1*EPC (Pressure Control) Solenoid,1*TCC (Lockup) Solenoid,Manifold Pressure Switch and I also have a filter and pan gasket. I see it takes Dextron IV, is it 7 quarts needed? I already have it disassembled and will be putting it back together today, I watched the same video but I was able to get the side cover completely out with a little maneuvering, I took all the mounts out except the rear mount again it's a 2008 HHR 2.4.
I noticed I had a rattle from the bad control arm bushing being shot so I was able to get a kit from eBay with 2 control arms with ball joints, 2 sway bars, 2 tie rod assemblies all from one buyer that ordered but never used them for $75 & free shipping and I also picked up 2 loaded strut assemblies off eBay for $90 with free shipping so I hope I'll have no problems with the front suspension and steering for a while.
I would say 7 quarts to start with is a safe bet.
You could measure the amount of oil drained from the unit and start there also.
You will have to have the car level and up in the air a bit so the inspection plug can be removed on the case to know exactly the correct level needed in the trans.
If you installed too much fluid to begin with, the excess will drain out until it reaches the correct level.
From what I've read, the top shift solenoid tends to burn out more times because that one is not covered in trans fluid, causing it to run hotter than the other solenoids.
I saw the level plug on the disassembly, I noticed that the transmission chain has some slack in it. I think I will just keep my eyes on Craigslist and pick up a used trans and maybe a engine and rebuild them at my leisure so when the time comes I can drop them in. I really like the car/van style and there's no rust anywhere. I've already done everything on the brakes except the master cylinder. I have a used BCM to install but after that I should be set for a while.
