2003 gmc sierra 2500 transmission issues

Asked by Zachary Sep 06, 2024 at 11:10 AM about the 2003 GMC Sierra 2500 4 Dr SLT 4WD Extended Cab SB

Question type: Maintenance & Repair

I have an 03 gmc sierra 2500 6.0 4wd,
Ive had this issue with two transmissions now,
speedometer and rpm gauges show 0, the truck is
shifting hard, ive tested 3 sensors that i have ( the
truck is only using two) all three were within 1.39 and
1.42 ohms. Ive checked my ecm ground wire at the
passanger rear of the motor and its in good
condiotion. I put my scanner on the truck and the
truck itself doesn’t know how fast its going. It wont
start by the key either. The only codes i have are as
follows.

P0137 pending - hos2 circuit low voltage sens 2
B2600 current - daytime running lamp control #1
circuit malfunction
P0502 fail since clear / current - vehicle speed sensor
circuit low input

Any thoughts or diagnostics would be greatly
appreciated. Thank you.
