is there a module on the tranny? Maybe put the old module on your new tranny? IDK if they have an electronic ID that your car is checking for.

 

TQ converter been checked for position?

 

Just spoke to a friend who is a tech at Rotolo Chevrolet. No Tech II programming would be necessary for a trans swap but, of course, they had no other advice other than 'bring it in and we'll take a look at it'.

 

Yes, there was a new module on the new transmission. We did try swapping it for the older one and still had the same problem. I am probably going to end up taking it in to the shop. We've already done the hard part and saved lots of money changing out the transmission ourselves that I can probably stomach the cost of the shop repairs now.

 

Are you saying that the eng. is turning over when you turn key or power go's off when you turn key to start and nothing happens

 

I am willing to bet that this turns out to be one of those forehead slap things. BTW, did you check the AT fuse? Linkage adjustment is "special" if I remember correctly.

 

The engine is not turning over at all. The only thing that happens when I attempt to crank it is that the lights and radio shut off, but the poster above says that's normal. I hear no clicking or anything in the engine even attempting to move or start.

 

Indicating that the computer thinks that there is some reason to not allow a start? Like neutral switch is not sending the correct signal. How about the remote start interlock/hood switch. Could be any number of wires that did not get plugged in all of the way. Many of those wires are (sort of) TTL signal wires and could be temperamental. Ground straps? The AT control module is under the "Darth Vader" hood in front of the fuse box, check the connector for pulled or frayed wires, and I am pretty sure that there is a fuse and/or relay for the AT in the under hood fuse box.

Please keep us posted, I am hanging on to a failing tranny myself.

 

What and where is the AT fuse?

 

Look under the cover of the "under hood" fuse box for a diagram. Mine says pos. 43 is the trans fuse and pos 26 is a trans relay. I am not an expert, just guessing at things, and I may be misinterpreting the labels. Look for anything that says TCM, trans, drive train, ECM, PCM etc. and check them. It is easy to pop a fuse while blindly plugging in those connectors, is all I'm saying.

I just looked at the "2006 HHR Service Manual" (PM me for info) in the "automatic transmission section" around page 235 for the cable adjustment procedure. Sounds sort of like the neutral/park switch is the problem, although the book describes the opposite, i.e. "starts in gear".
