    2010 Challenger SRT8 Procharger Build - A580 clunk low load 2-3 and 3-4

    I've been helping a friend with his challenger build. Everything is working great at this point except the trans is clunking 2-3 and 3-4 under light loads. I'm guessing it's a shift pressure issue but I need help with the A580, and because it's not my car I don't want to trial and error it to death. I'm going to be getting together with him later this week so I'd like to have a plan of attack. Here are the files:

    I wanted to post a follow up for others that came across this. I solved the issue by disabling upshift torque management in the TCM. I left trans torque management enabled on the engine side.
