Hi. There is a speed sensor mounted on the transmission. Check the wires that lead from the sensor to the instrument cluster in your dash. Make sure the speedometer is connected to the sensor, and the connection is not loose. If the wiring at the sensor, and speedometer are ok, simply replace the speed sensor.

yes mileage is stored in bcm not speedometer cluster

You will have to check and see if there is a poor connection down on the transmission tail shaft or transfer case tail shaft. checking for broken or corroded wiring. the other thing is a bit more expensive you will have to replace your IPC (Instument Panel Cluster)

Hey Larry , Silverado are notorious for heater blender door problems, look at accuator its controlled by vacuum and possible something got down there and its jammed.

Google your codes & read up

Torque specs for what? Headbolts, rods, mains, ring gear, lug nuts?

It's inside the IP. There are resistors in it that seems to drop out all the time. I haven't figured out if it is a bad solder joint or from heat. But I fix them all the time. They are about 3/8 inch long X 1/16 inch in diameter. Dark brown in color. Located on the top of the board on both left and right sides. They do fall off. So be carefull when you open up the IP. They are hard o find on dark carpet.

I don't know what "timming" or "minic" means, but (from context) I'm assuming you think that you are having some kind of a a TIMING chain problem. The timing chain simply goes around the crank shaft sprocket and around the cam gear, turning the cam shaft. If it is in place, your vehicle will run. If it breaks, the vehicle will not run. If it is loose, your vehicle may run rough, but there will be an obvious rattling noise coming out of the timing chain cover at the front of the engine, as it moves the tensioner aroundr. That's about it for a timing chain. There is nothing else to it. Hope that answers your question! Now if you have an actual SYMPTOM you'd like diagnosed, try again.... and use spell check :)

Remove the Transmission pan. It is the larger one of the 4 solenoids, it is the rearward one of the set of solenoids. Usually a black color and round like a small pepper shaker. If you are replacing this one, you really should replace them all. This governor pressure sensor, when if fails, usually causes the transmission to start off in 2nd gear and then upshift to other gears is delayed and harsh.

Code po449 is for bad  solenoid vent valve.After replacing the valve  check for the   12 volts at the "pink" wire.
This error relates too 

The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Definition:
EVAP (Evaporative Emission System) purge/vent solenoid circuit condition

Explanation:
The solenoids and system wiring are monitored for opens or shorts

Probable Causes
1- Purge or vent solenoids defective.
2- Check connector and wiring.
3- Fuel saturated vapor canister.
4- Failed EVAP vent solenoid.

The cost of the vent solenoid valve is near to 30 bucks. And the valve is located near the gas tank.

More then likely the switch is bad. This is one of the most common failures, even if all the other switches work, doesn't mean that one switch couldn't be bad. Start testing power is you can I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_677dced97ad9bddf

these trucks are equipped with an electric vent door motor known as a vent actuator. I believe the actuator that controls this vent is located behind the dash on the driver side.
