My truck is back up and running now, but unfortunately the TCC slippage issue is not completely resolved. It is significantly better, but it starts to slip at about half-throttle in 4th gear. It's at least working well enough to allow me to continue working on the Arduino controller. I'm thinking I'll tune the vacuum sensor trip point to unlock the TCC before it starts slipping. It's not a long-term solution, but I've got other things I need to spend money on right now.
