It will be low transmission fluid, blocked filter or problems with the solenoids. Best way to fix is to call a mobile auto electrician with a pro grade scan tool to diagnose the issues. Their tool is bi-directional and can command solenoids to operate and verify that they have.
sounds like your overdrive solenoid is bad. Best to take it to a trans shop. be forewarned they are going to wan to sell you a new trans, depending on the mileage they might be right.
Sounds like anti-theft system problem ! There is a little red light center top of dash pad , When you try to start the vehicle does the light flash fast ? If the vehicle thinks it's being stolen it won't let truck crank over an it turns off the fuel injectors !
Remove door cover and see if there is power getting to the electric motor with a test light,check if power is getting to the switch,check relays first.
may need clened because its not recognising a disc.. get a can of dvd spray with the tube on it(like dusting spray) and insert the tube and inch or so inside the slot..spray short bursts of spray into the unit..wait a minute or so and retry..repost findings..
