2003 gmc sierra 2500 transmission issues

Asked by Zachary Sep 06, 2024 at 09:21 PM about the 2003 GMC Sierra 2500 4 Dr SLT 4WD Extended Cab SB

Question type: Maintenance & Repair

I have a 2003 gmc sierra 2500 6.0 4l80e 4wd. Ive had
issues with two transmissions with it shifting hard, no
speedometer or rpm gauges, and no start by key.
Replaced neutral safety switch, checked speed
sensors, checked out between 1.39 - 1.42 ohms.
Checked my ground wire for the ecm and its intact.
Ive hooked it up to live data, and the truck doesn't
recognize how fast the truck is driving. Any help
would be greatly appreciated, thank you
