[IWantATurbo]

i have my tune that i have been slowly working on, and it makes it run but my trans wont shift just stuck in 3rd. my donor car was a 06 Silverado but my trans is a 2wd out of a 03 trailblazer.

so i took my toon and an 03 camaro stock toon side by side and changed everything in the trans folder that was different. then tried to write it and it wont upload and says wrong ecm how can that be?

Im lost as to what i did wrong?

There are no 03-09 MY Camaros.

Oh ok.

Looks like there is such a thing. Would it be ok to reference an 02 file instead?

Ok I managed to find a tune for a 2003 camaro. It was difficult track down because the only place they were sold was Djibouti. I've attached the file for future reference.

Interesting VE table. I wonder what kind of intake manifold came on these 03's?

Sounds like it is unpowered. Does Pin E on the transmission connector have 12 volts?

It doesn't come from the PCM. You need your own diagrams/service manual if you are going to work on this thing yourself. Otherwise pay someone to do it for you.

You need to check AT THE TRANS, no matter how hard it is to get to, because that power wire is the one that is real common to back out of the connector for some weird reason.

???????

That's great. Is the wire and its terminal making connection to the mating pin in the trans-side of the connector?

[IWantATurbo]

did not have to put my peace of wire in very far to get power
