Ok so far we got...
P0161 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 2 Sensor 2
P0446 - EVAP Vent Solenoid Valve Control System
P0740 - TCC Enable Solenoid Circuit Electrical
P0785 - 3-2 Shift Solenoid Circuit Electrical
P1860 - TCC PWM Solenoid Circuit Electrical

Let me check some more...

From what I can tell this one is gas cap related. Check filler neck, vent holes are not plugged and gas cap seal and Integrity.

The last 3 appear to be transmision curcuit wiring possibly in steering column,
or ignition switch itself....anybody else?
I'm pooped after that...

By the way br2819, when you get a chance. In the Top/Left of this web page(User CP) could you edit your signature, To reflect your Truck. So we know what your driving for future referrence. Thanks :biggrin:

Was the remote start an aftermarket unit? Dealer installed or other?
