I got 2009 hhr LT was automatic but my tranny run out so I make it manual now but I got some problem in the rpm,rpm not want pass 4000 what I can do I know I need remove the ATCM or make some bypass any help thank
Unplug the TCM. The standard trans doesn't have the sensors that the auto had. I don't know if you will need to reprogram the ECM, maybe use the ECM from the donor car.
Not many have ever done the swap and none that did detailed the work here. I'm just guessing.
Why did you do the swap if you didn't know how?

I know how do swap
my automatic trans run out the swap is perfect my car run everything work but the only thing is the RPM and if I unplug the computer for the automatic transmission the car not want crank
I believe you’ll need to swap out the wiring harness for a harness from a standard trans car. May also need to swap to the ECM from the standard trans car and get it programmed to your car.

some people told me the same thing the issue is the donor is no more longer available so I need found one in eBay if a got luck if not do Programmablewhit the mega squirt or fuel tech
This is what I meant by "not knowing how", any body could bolt one on, making it work is a different thing. Would have been easier to just put an auto in, or buy a HHR with a 5 speed.
Did you wire in the clutch pedal position sensor? That is required to replace the park/Neutral switch on the auto for starting. I guess you could probably just short the wires as a proof of concept. The D-GN wire in the TCM harness should go to ground to enable starting, if it was a 5-speed the CPP would be a L-GN wire. (I think). Actually, that wire goes to the ECM, on an auto it goes to X1/pin 67 on a 5 speed it is X1/pin 45
Maybe, go to a junkyard and get the ECM and harness from an HHR with the same engine and 5 speed.
I hope that pic is not implying your next project is a turbo in a LT. That will be even more involved and possibly fatal to the engine.

Is not fatal for the engine I figured out thank and yes that is my next project the only one in my area manual trans whit turbo at least 25 psi thank for your help this is another pic for the engine I have too many year of this industry this I do for leaving
