u may have a brake fluid leak, bad master cylinder,

selinoid ? Solenoid Wouldn't think so , but you never know without testing . With the truck running you step on the brake which let's you shift from park into a gear . That part works right ? Automatic Transmission Shift Lock Control Circuit Description The automatic transmission shift lock control system prevents the automatic transmission from being shifted out of park position unless you depress the brake pedal with the ignition in run or start. When the ignition switch is in run or start, the current flows from the BU/LPS fuse located in the engine wiring harness junction block through CKT 839 (PNK) to the park/neutral position switch. The park/neutral position switch also feeds the backup lamps portion of the switch. With the transmission in park, the current flows to the automatic transmission shift lock control fuse located in the engine wiring harness junction block through CKT 275 (LT GRN). The current then flows to the stoplamp switch through CKT 584 (LT GRN/BLK). The current continues to the automatic transmission shift lock control solenoid through CKT 1135 (DK GRN/WHT). The ground path is provided through CKT 1850 (BLK) to G203. When you depress the brake pedal, the normally closed contacts in the stoplamp switch open and the current flow is interrupted. When the current flow interrupts the automatic transmission shift lock control solenoid de-energizes. The transmission may then shift to another gear. Once the transmission shifts to another gear (except park), the contacts in the park/neutral switch are open thus stopping the current flow to energize the solenoid when the brake pedal releases.

You can program it if you have a good scan tool,or take a trip to a good garage in your area,they will have one and fire up your radio.

Should be 4-6 bolts and nuts under the truck on the front of the frame rail

It sounds like the "SCAN" button is hung up. Try hitting the scan button again to turn it off.

I should just pry off

Your instrument cluster may be going out.

You need to change the bulb in the Left front lamp. I hope this helps. Take care.

First thought- defective cylinder. Now when you say blown out do you mean came apart and the cups and cylinders came out? If that is so then I would say faulty installation. The cylinder rod may not have been installed correctly. Or the shoe hold down springs came apart.

A 1999 Silverado does not have vacuum lines to the transmission. It is fully electronic.

Have you tried setting the time on your clock? Owners manual should walk you thru the steps.

It should be under the truck inside the frame rail about 5 or 6 feet behind the front wheel on the drivers side

Can park be selected by going under the vehicle and manually pushing the gear selector into the park position? If so then cable adjustment is next.

Did you have the vehicle scanned for DTC'S - diagnostic trouble codes ? That's the place to start , not at auto zone ,pep boy's ,advance etc.... Qualified repair shop that has a professional scan tool , scan all the modules on the vehicle .

I hope you were not in the middle of no where when this happened. First before you take off the nut mark it with a scribe so you can see where the not sets on the pinion shaft then count the number of turns it takes to remove the nut. When tightening the nut back, just realign the marks. Since the seal is still leaking it may have been damaged. Make sure to lube it before installation. I usually fill the area where the spring sets with grease. Watch this video https://www.youtube.com/watch?v=lD8QNQATrNs
