2011 chevy express no commo to the tcm

Ok so here is what I've found for any future reference. First- battery voltage was good checked both batteries. 12.4 volts on both batteries. Second- Disconnected batteries and pulled TCM. Third- Checked continuity between pin 9 and pin 69. Good continuity of .03-.04 ohms Fourth- Checked all grounds Fifth- Reinstalled TCM, and Reaatached Batteries. Sixth- Checked for power and ground at the following pins: Pin Connection 10 Battery +--- Good 70 Battery +----Good 9 Ground--------Good 69 Ground--------Good *****43 Accessory Power----***No power here, or I should say not battery voltage, with key in the accessory position or in the KOEO position. What should it be? I couldn't find the specified voltage. 63 Ignition Power 58 ground After that I started the truck, and it went into manual and showed the gears. Scan tool showed no loss of communication codes after I cleared them. Turned truck off and then left it with KOEO like you would to read codes, adn clear them( previously where it would not communicate with the scanner) Communicated fine and showed no loss of communication with TCM at all or pending. So if that means anything to you let me know haha

where is the location of the TCM 2011 chevy g3500 espress

Good day. Have a problem with my 2007 Chevy Express 2500. Starts out and drives fine for about an hour . After transmission starts shifting really harsh. Not sure why.

I had the no indicator, hard shift or no shift, and no tow haul and code u101 and it was all caused by a bad connection in the abs controller plug
