I posted this in the transmission section, but thought maybe somebody in this section may have some insight. https://ls1tech.com/forums/automatic...dtc-p0785.html

That is the 2-3 upshift solenoid. I just went through a similar bout. I also had P0740. Turned out to be the stop light switch was incorrect, not applying 12 volt signal. Seems like others have simply replaced the solenoid when that is the only issue. Seems straight forward enough.

Here's a diagram showing the 3-2 Solenoid.
