2022 LoneStar just over 11k on it. 3 months ago they had to replace the transmission valve body cause the thing went into limp mode, would shift, no power, auto s/s didn’t work. They kept it for 2 weeks. Said the issue was fixed. Just got in the truck this morning to drive a short distance and the transmission was being odd. Then the light came on three code U0402 and all the same issues. What is this?? How do I fix it? Is it going to keep happening? Did I get a dud. If so bye bye RAM.
