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!
