Thanks so much for all the knowledge, I have found a friend who has a lift and know-how who is willing to help so hopefully between my engineer crazy brain and his wrenching along with the fine knowledge we have here I can maybe get it fixed a bit cheaper going slow and methodical. Glad I work from home! Thanks so much guys!

Thank you - I appreciate the info. I had feared it was pretty serious due to age etc. Will see if I can find a decent used one to swap out and while the TCM doesn’t appear to be cheap it will still be cheaper than a whole new unit and labor. Thanks again!

Just to point out - I am not a mechanic, but I am trying to educate myself before I take it somewhere to have it looked at as I am broke and if this is something I might be able to at least purchase aftermarket and get a friend with some know how to do I will. Any help is greatly appreciated. I have a 2007 2500HD, VIN 1C6SRF JT2KN890086 Transmission slipping once hot. Not doing any kind of heavy driving. Checked and filled fluid properly, not overfilled. Had fluid flushed at a shop. Still slips. Not consistently however. No clear direction from the shop other than taking it to a transmission place which will likely cost me dearly I’m afraid. Are there any specific known issues with these transmissions I might check? Are there any controls or computers or modules that tend to go bad that would cause this. Any other steps I could take that would allow me to troubleshoot further? Thanks again, motogrrl
