The transmission and speedo COULD be the VSS (Vehicle Speed Sensor) and or related wires. The Tach is a seperate circuit that gets signal from Distributor and power is fed through the "Gauges" fuse. The only way I see them being a related concern is either The ground (G200) and is located Behind the left side of the IP, below the fuse block, on the tie bar. the other way would be the IP cluster itself.
I think you MAY have 2 issues. I would get the VSS checked and make sure your getting a signal to the VSS buffer (located next to the PCM, around the glove box area). Make sure the buffer is sending the signal out. A Scan tool SHOULD be able to assist you in this. If there is NO VSS signal the transmission will not shift properly, if at all.
Also your speedo will drop off with no VSS.
As stated, this is just advise from experience and published material.
If in doubt, please take it to a Repair shop in your area your familiar with. regards ranjit

Check fuse 55 in the eng. comp. and check the power fuse "alt pwr" 20A in the driver's side fuse panel on side of dash.
I melted my right side power plug with a portable compressor and blew the fuse in the dash panel. I need to get a new power plug now.

You need to replace cluster, 99-02 Silverado GMC all will work even if it has a trans temp truck is pre wired for it. I put a 02 Denali cluster in my 01 silverado no problems. GM can reprogram hours and odometer if you want.
