Hello all new here, just purchased a 06 Commander 4.7 limited with 108,000 miles on her. Drove it home 2 hours later I go too get food and transmission goes to 3rd gear and I get a engine light. So I shut the vehicle off and restart still same issue I go get my scanner and it’s pulling 5 codes 0700,0846,0882,0988 and 0781. Now I know what the codes are but does anyone think it could be just a bad TCM or possibly a short in the harness? Really trying fix myself before I go to the local shop. BTW no help from the place that sold it to me so any and all help is much appreciated!

What I would love to know is where is the TCM? I have read that’s it integral with PCM but have also read that’s it’s a stand alone. Have not been able to find anything out at all. I also getting trans over temp service 4wd system with the key in the on position not running I go to start and nothing just clicks. I checked the yellow wire all good there all the grounds are tight.

@Mr.Dave007 I'm not certain where the TCM is located right off hand. But it might be one of the modules under the 2nd row seats. Check there.

Another question is there any particular place these harnesses tend to break or get chafed? Worked on it all day yesterday could not find and breaks anywhere.
