Hi guys I'm new here , I drive a 08 duramax 2500hd 6spd. Allison transmission, all stock . Today I got in my truck to leave to work and engine light came on and the message "engine power reduced " came on and I could not accelerate . I turned around , used my scanner to check for dtc . There was 3 codes all U codes lost communication with pcm , lost communication with AT and another communication codes . I performed a snap shot and evaluated all my inputs and outputs from the sensors etc. Everything appears to be normal , my only thoughts are possibly a bad battery or batteries ? Have any of you experienced this? I keep up on all my maintaince and I have a 100k on my truck as of now .
Thanks
Thanks
