Has anyone seen where the early 8 speeds have terrible maps and terrible converter lockups? I have gone through a lot of the drivetrain to see if I can see anything loose or any issue and I have not seen anything. Everything looks great. My main complaint is when I am stopping I get some clunks and shudder. Also when accelerating or taking my foot off of the gas and reapplying it it feels like it clunks sometimes. I took a quick drive around the block and logged some parameters. Don't know what im looking at since im so green to tuning.
