Stock TCM Parameters Needed - 2006 Trailblazer SS T42

Hey All,

Looking for some help on the stock settings for a 2006 TBSS TCM (OS 24235341). I am replacing the transmission with a built one and want to put all the settings back to stock. The TCM was tuned by the previous owner's tuner so I don't have access to the stock file, and I can't find a stock file for download anywhere. I have 2007 and 2008 stock files, but I'm told the 2006 was different, and even these two have a few differences between them, so I'm not 100% sure.

I'm mainly concerned about getting the baseline shift pressures, force current motor, and TM settings right, but if anyone has any other helpful input I'm all ears. Thanks!
Brent

Hey Brent, if no one else posts one today, I'll grab my external HDD and pull the stock 06 TCM file I have and post it up later tonight.

That would be great, thanks a million! I think the 07 and 08 files I have came from another thread where you posted those too. :thumb_yello:
I really appreciate the help!

This is a stock 2006 Trailblazer SS TCM file. It is also up to date.

Awesome, thank you Al!

They may well be Brent, a few people have asked for them over the years! (I have 09 files too BUT they're a bit different as GM went to the different style 4L60/70E for 09+.)

06 and 07 TCM OS' work together with the 06 and 07 ECM OS' too.

Perfect, just what I was looking for! Thanks to both of you for the great support!
