One version being the early version of the Duramax pre EGR engine called the LB7 and the other being the LLY engine. We won’t candy-coat it, the water pump’s design is flawed. Originally began having transmission issues in Nov 2020 with surging while stopped in cold weather. 6, claiming to use nearly 60% of freshly designed parts not used in previous version. 6L, but this is not the ticking or cycling that I have heard on my previous Duramax.
