Location of TCM
I have a 1500 Chevy Silverado 2009 model (with some 2010 parts because it was produced in Oct) and I have exhausted all means of trying to find the transmission control module. The transmission was just rebuilt a couple of years ago and now it’s acting just like how everyone describes as a bad TCM. I tried resetting it two different ways and it didn’t help. I can’t find it under the hood or dash. I’ve watched literally hundreds of videos and read Google and everywhere it says it should be….its not. I have a new TCM just need to change it out. Thanks
