Automatic locks and tranny problems
SO IM GONNA TRY THIS ONE MORE TIME A FEW MONTHS AGO I ATTEMPTED TO GET HELP FROM THIS SITE BUT APPARENTLY I STARTED MY THREAD THE WRONG WAY, SO IM GOINGBTO TRY AND DO IT THE RIGHT WAY THIS TIME. So my 06 hhr won’t engage the automatic locks when shifting from and out of parking and when this happens a number of problems accur 1. Transmission won’t shift into 3rd or beyond 2. Cruise control won’t engage 3. Locks in the car will sometimes lock and unlock themselves, when I started having this problem was in the winter and I got the battery, and charging system checked and they all passed, a mechanic of mine hooked up the scan tool and 3 codes came up B2705, B0595, and B3006 I should note that I can move my gearshift in and out of park without applying the brake and even when the car is off, the car use to belong to my dad MAY HE RIP😔 so this car means a lot to me and I wanna get it fixed but it’s really fighting me I took some videos of the symptoms the car makes and I will share the links, as I mentioned the car belonged to my dad so I’m not 100% sure what kind of maintenance and work was done, but if their is any questions I can surely find out.thanks |
What you did wrong before was not answer questions or give exact details.
Now we know what is wrong, it is right there in the pic. Check with a GM dealer the special extended warranty may still be in effect. The reason for the lock connection is that the doors are programmed to lock when the gear selector is not in park and can be programmed to unlock when placed into park. This might be caused by the park neutral sensor switch mounted on the transmission where the cable is attached. Might be the brake pedal position sensor. The cruise control is probably because the CHMSL (the third brake light) has a bulb or 2 blown out. But may be related to the malfunction. Does remote start work? is there a seatbelt/airbag warning? Has an after market security system been installed? Can you move the lever out of park without stepping on the brake? Have the ignition switch recalls been done? Was this going on before the radio and nav was installed? |
Here is the test procedure, step 13 is run the engine see if the code comes back.

Was this going on before the radio and nav was installed? the ignition switch recall was done about 3 or 4 years ago I remember because the key would get stuck and we had to stick our finger underneath to get the key out, the remote start doesn’t work, I bout the FOB remote on Amazon but I went to a Chevy dealership to have it programmed but the remote start still didn’t work even after, but I didn’t have any of the current problems I have right now, I did replace about 2 light bulbs in the 3rd break light but I will have to double check if they went out again, no seatbelt/ airbag warning lights, yes I can move the lever with out applying the break, and no this was not happening before or after the radio was installed. |
The ignition recall really had nothing to do with "key stuck", however that leads us back to the gearshifter lock control solenoid. That is not serviceable by itself.
There was a special warranty that covered a new shifter assembly, I think that expired. Check with GM. There was a "stuck in park" problem also. What this is telling is the solenoid is stuck. Could try spraying it with some WD40 or the like. It is on the side of the shifter assembly. Neither of these address your specific problem, but you can visualize what I mean. https://www.chevyhhr.net/forums/how-...ark-fix-52951/ https://www.chevyhhr.net/forums/how-...-delete-39229/ There is a nylon bar in there that pushes the micro swicth that energizes the solenoid. Another suspect I have is that many nav systems are wired into the gearshift. That connection may be doing something if it is there. Thats why I asked about that. |

The micro switch has disappeared! It should be attached to those 2 wires.
New assemblies used to be on eBay for around $100. All years work. like this among others. https://www.ebay.com/itm/GM-OEM-Cent...kAAOSwXXxZQ4r1 If you want a used one send a PM to hellshotrod, he has several HHRs he needs to liquidate quickly. |
Extended coverage for the shifter is still in effect.

Does anyone know if there are part #s for these 2 pieces that I circled in the picture because they are missing in my assembly and I want to at least replace them before I even attempt to call Chevy to see if my assembly is under the warranty I don’t want them giving me an excuse they can’t because of a missing component.https://cimg4.ibsrv.net/gimg/www.che...4e7f20f4b.jpeg |
There are no part numbers, as I said earlier they are non-serviceable. Brand new assemblies are $65, used cheaper. Now that you have done all the labor yourself it really isn't worth putting it back together, is it?
|
David’s most likely got one, maybe even from an 09,10, or 11

Well I replaced the gearshift assembly from the junk yard it has the all leather handle it looks like a newer model, fitted everything but no luck, I noticed that the lever that is in the driver’s side doesn’t even pull back when I press the brake, my door locks still did the same thing open and close by themselves while parked, so I removed the door fuse to see if it made a difference and watch the YouTube video that I attached to this reply that’s what my car does now with the newer gearshift assembly and door fuse unplugged (sigh) https://cimg6.ibsrv.net/gimg/www.che...782d9e75f.jpeg |
Have you checked your brake lights. The brake switch is what is supposed to unlock the shifter.
Next would be the neutral/park switch on the trans, that probably is the door lock thing. And maybe the cable connection there, maybe it is not staying in the "drive" position. |
How does the neutral/park switch look like? |
It is where the cable attaches to the trans.
Those are the only other parts I can think of that could wear out, everything else would have to be cutting wires or rerouting electricity. I am guessing that the BDM gets the signal to lock the doors from that switch, can't think of anywhere else. The shift cable has been known to wear out as well as the ball connector. https://cimg1.ibsrv.net/gimg/www.che...c7cc0043e9.png |
Here is how to adjust the cable
https://cimg7.ibsrv.net/gimg/www.che...0e851730ce.png Here is how to install and adjust the switch, if anyone has been in there this is on my short list https://cimg6.ibsrv.net/gimg/www.che...cee313e69d.png |
Am I missing a fuse to the TCM? https://cimg3.ibsrv.net/gimg/www.che...9a5f5a41b.jpeghttps://cimg4.ibsrv.net/gimg/www.che...0ec1d99b6.jpeg |
First, that wire attached to the power steering could cause problems. If it is supposed to be always hot and has an inline fuse a safer place for it would be the other outside terminal.
Secondly, page 5-84 is really mis leading in the way they patched it together. The legend that you have circled actually belongs to the picture on the previous page, the inside fuse box. Position #25 under hood is for the fuse puller. https://cimg0.ibsrv.net/gimg/www.che...c6c10058ca.png |
Underhood fuse box
https://cimg6.ibsrv.net/gimg/www.che...4f5cf768e.jpeg K I need a better picture! https://cimg8.ibsrv.net/gimg/www.che...eb6c359d4.jpeg Fuse puller |
Ok thanks guys, I checked it by the passenger side and all my fuses are good, I also disconnected the TCM and checked for any corrosion but all was well. I took my car to AutoZone to get any possible codes pulled but they said there where no active or pending codes. My brake lights work and ended up just putting a zip tie to prevent my shifter from ever locking up again. So I guess this weekend ima gonna check the safety switch. |
It would help to know what other modification were made. Obviously somebody thought the shift mechanism needed to be torn apart and modified so the safety systems are disabled instead of being repaired under warranty. They did send letters to registered owners a few years ago.
How many stories of a dog or a child pushing the lever into reverse and causing damage and death? Wait! Now you are saying the lever was getting stuck after you put the new one in? Can you hear a click from the gear shift when you step on the brake (lever in park)? If not replace the brake pedal switch/inspect the wires. Do the door locks still click on/off? Gauges still wonky? Try this, add some dielectric grease to the connector pins |
The gauges aren’t wonky in the winter they kinda were but now only the fuel gauge kinda but very little does it do that, from what I know and visually inspected no other modifications where made. When I start the car in the morning after sitting over night the car drives perfectly fine shifts into gears normally, it isn’t until I stop the car and out it in park when my shifting and automatic door locks start to lock and unlock by themselves every 5 minutes or so. The weird thing is that when the cruise control works after I place the car in park and begin driving again if my rpms are around 4,000 and the car isn’t shifting into 3rd, when I engage the cruise control and it actually activates the rpms will drop to around 2,000 and transmission will shift normally. I’m getting ready to change the brake switch even tho I did hear a click before when pressing the brake pedal but to avoid locking up on me that’s why I put the ziptie and I’m going to buy the dielectric grease . |
If it drove with missing parts in the shifter some other mod was made.
Somebody did something to the car that was a intended to defeat safety interlocks, now that "fix" has failed and the interlocks are causing problems. |
Like what? |
No idea. People don't understand that the car systems are interconnected and controlled by computers. Simply tapping into the wrong wire can shut it down. At this point you need to basically rebuild the electrical system. Take the fuse box apart, look for taps cut wires everywhere. Disconnect connectors inspect them add dielectric grease etc.
Where does the wire off of the PS go? That shows some inept installation. What about OnStar? Has that been messed with. It is connected to the OBD2 system, if somebody yanked the wrong wire it could cause problems. |
Hmm, I’ll re read this thread and get back to y’all.
Hmm, yeah , let me see..... |
