Got a chance to take a look this afternoon. I’m getting good voltage at what I think is the A8 terminal (although without a better diagram I cannot be 100% sure). Looks like that means it’s time for a new TCU. I’m still a little suspicious that I had a failure at the same time I changed the fluid, but maybe the fluid change and initial low fluid level revealed an issue with the TCU that had long been lurking? I’ll go ahead and order the part now and when I get it installed I’ll be sure to post back here with the results. Big thanks for your help and patience College Man!
