I recently got a P1860 code. I changed the trans filter, fluid, TCC PWM solenoid and both shift solenoids. Once I reconnect the battery, the codes don't come back until I shut off the vehicle and restart. Any ideas would be helpful.

I think it's a bit more complicated than just replacing the parts and disconnecting the battery. First of all do you have a scan tool able to read and clear body, chassis and transmission codes?

Maybe someone with a bit more transmission experience can chime in here? I don't think a battery disconnect will erase transmission pending codes or learned parameters. A tech2 may be needed or have a trusted transmission repair shop look into it. Good luck
