2004 Gulfstream Crescendo will not go into gear

Been sitting for a bit due to health. Had to remove batteries to charge. Started up no issue. But the indicator for shift didn’t come on and error message saying “parking brake set in gear”and “trans ecu no data over 24 sec.”. I pulled both connectors off ecu and put back on. Nothing. Can’t put RV in gear. Any thoughts?

Check in the battery compartment for a power/ground wire that got missed. It sounds like there isn't any power to the ecm. If wires are hooked up, look for a fuse on the power side from battery to ecm. People have spent a lot of money because of a bad fuse or fuse holder.

Great idea. Do u know which batteries r responsible for that? I ask because when I charged the front 2 I took pics and hooked back up same way but forgot to on back 2. Wonder if I did something wrong with those back 2 which I believe are the accessory? Hard to find pics and diagrams as u know.
