Thanks, bangingd. I feel it's probably the torque converter too. I suspect the transmission downshifting from 4th to 3rd would be a much bigger rpm change. I like your suggestion, but I can't figure out which PID to display. The only ones I know of that directly relate to transmission gearing are the OSS and TSS (Output and Turbine Shaft Speeds). I used to monitor these when I first got the programmer, but decided they weren't telling me a whole lot. Is it one (or both) of these? (And if so, I don't ever remember seeing a "lock" but this could be another of my "senior moments").
