There is a recall on the 2003 instrument cluster on your Silverado. Check with the dealer before the warranty extension is over and you end up paying for a new cluster. As for the transmission, check the transmission fluid level and have the transmission scanned for any DTC codes that may indicate an issue like a faulty TPS sensor which is a simple that can cost you a expensive transmission repair.
Good luck and keep me posted.

Why does speedometer read 65, when I'm only doing about 35?


Circuit/System Verification
Important: If the suspect gage is the speedometer, the drive wheels of the vehicle must be raised and the transmission must be placed in drive or first gear.
  1. Ignition ON, with the scan tool, perform the IPC Gage Sweep Test in the IPC Output Controls. Verify that all gage dials move from minimum to the maximum value and back to the gage minimum value.
  2. ?‡'
    If the gage does not perform the IPC Gage Sweep Test, replace the IPC.

  3. Start the engine, with the vehicle drive wheels raised and place the transmission in drive or first gear. Verify that the speedometer value matches the scan tool Vehicle Speed parameter in the ECM/PCM Engine Data List.
?‡'
If the speedometer is incorrect, test or replace the IPC.

Trasmission sleeps somtimes the gear works other times it doesnt


there are many gears.
are all gears dead, forward and reverse
even at 3000 engine RPM?
is the transmission slipping
if RPM gets stuck at say 1500 to 2000 that means the brakes are frozen in ICE.

My rpm gage is not working, my speedometer is not working, my gas gage is not working, and my oil gage is not working, and my temperature gage is not working pretty much when i start up my car and drive it...


I'd wager that the fuse that controls the gauges is shot, or one of the internal connectors got unplugged (Fuse sounds more likely). Radio, Lights, and Turn Lamps are usually on seperate circuits.

Rpm goes up and the speedometer doesnt move and it putts down the street till it catches..doesnt do it all the time...a auto guy told me it was the ignition module and the ignition coil, and he said it...


Unless you are getting a false rpm reading, then your transmission is indeed slipping. Does the engine speed up in conjunction with the tachometer? If the answer is yes, you do have a slipping tranny. Good Luck, I hope this helps.

Electrical and slipping Transmission


Transmission and gauges are probably unrelated. My '98 Caravan had 2 bad solder connections on the back of the instrument cluster where the connector attached. It takes about 10 minutes to get the cluster out. The bad solder joints were easy to spot on mine. It took 2 years for me to find the problem, but only 30 minutes to fix it and it hasn't happened again since (almost a year).
