2007 SS Trailblazer Won't Accept Trans Tune

I am working on a 07 SS Trailblazer, I read the tune made some changes in the engine and transmission and saved the file, and tried to flash it and it came up with a error, it was a 1C0000 error, I did a write entire, and the issue went OK......But none of the transmission changes took place, just the engine. I did this 3 times just to make sure it wasn't something I did wrong, same out come every time. No transmission changes just engine........

Any tips?????

Thanks Mike

when you get the 1C0000 error just do a write entire.

I have had a couple read issues with the E38/E67 PCM's where the TCM didn't reset after a read. Try pulling the TCM fuse(s) and that should cure the problem. Oh and do a write entire so it programs the TCM as well.

I did the entire write but it didn't take the trans changes, as far as the fuse when should I do it?

Mike

Pull it/them for 30 seconds. There may be 2 TCM fuses. Then try write entire again.

Thanks I will give it a try......

Mike

Well finally got the SSTB back and pulling the TCM fuzes worked !!

Thanks for the help
