    2001 Avalanche Speedometer

    Hi Guys,
    I Tried Tracing The Wiring On A 2001 Avalanche But Got Stuck Midway. The Wires From The Vss Ended In A Circuit Board On The Left Of The Dash, The Speedo Wire From The Instrument Cluster Also Ended In Another Circuit Board Under The Steering. Now The Tranny Is Not Shifting Because The Speedo Is Not Working. I Have Changed Both The Vss And The Instrument Cluster With Known Working Ones.
    Any Help Will Be Appreciated Especially With A Wiring Diagram From The Vss To The Instrument Cluster.
    Thanks For Accepting Me Into The Fold.

    NO DTCS ARE STORED WHEN SCANNED.

    I don't think the trans has anything to do with your speedometer not working my friends speedometer broke and it's stuck on 20 mph and still runs fine.
