Hey Fellas,
My 2003 Chevy Duramax/Allison was running fine last week, then I added the Hypertech model #30029. I corrected the tire size for 285-75-16 's and put it on level 3. I went on a 120 mile trip to let the Allison learn and drove it easy, because my wife & kids were with me. When I started driving the next day all kinds of codes set.
P0700-TCM
U1800-lost communication with fuel injection control module
U2104-controller area network-bus reset counter overrun
U2106-powertrain control module
U2105-lost communication with engine control system
C0035-left front wheel speed sensor
C0040-right front wheel speed sensor
C0055-rear wheel speed sensor
P0380-glowplug
P0880-TCM power input signal
P0742-torque converter clutch-stuck on
P1093-fuel rail pressure low
The truck shifted hard from 1 to 2, normal from 2-3-4, and wouldn't shift to 5th until I ran it up to about 65 and let off the gas. I've put it back to stock settings, changed the fuel filter, the spin-on filter, and changed the trans. fluid even though it smelled normal. I change the spin-on every time I change the oil. It still shifts the same and sets the same codes.
I called Hypertech twice to see if they had heard of this before, but that was a waste of time. The local dealer checked and reflashed with factory settings. They said some of the parameters were completely blank. When they said leave it for a couple of days, I ran.
Truck is stock except tires, Hypertech programmer, and a tank of bio now and then.
Great site and thanks for any help in advance.
