Transmission doesnt shift properly and CEL when remote starting 2003 trailblazer

0 votes
Did an install on a 2003 trailblazer. ONLY when using the remote start it throws 3 codes P0740, p0785, p1860 all pertaining to the transmission. If you clear the codes, and dont use remote start they do not come back. I made sure the 2nd accessory is an accessory and not an ignition. Any idea what I may be missing? Using D2D

Either an ignition or accessory is not being powered or its not powered correctly. That is what causes this issue.
