The block, rods, and pistons on prior Duramax engines were common failure points on tuned and modified engines due to weak components. All of these items received upgrades in the LML Transmission Problems. Nearly all Duramax powered pickup trucks were equipped with the Allison 1000 automatic transmission, with the five-speed version running from 2001 to 2005, and the six-speed starting in 2006 and running until 2019 This eliminated the problem LMM's had where diesel fuel would wind up in the engine oil, which could lead to major problems. So, by relying on an external fuel source for a DPF re-gen, the LML kept its oil free of any fuel dilution. Speaking of fuel, the LML was the first Duramax to be able to run on a B20 blend of biodiesel Problems like this are normally do to having a tune file that isn't meant for the truck, and it freaks out.
