Just looked and saw it for myself now. That's awesome. Do you know what the threading was that your unit s then? I'm guessing it's an NPT. I bought another Autometer Autogage 2355 to use as a transmission temp indicator, it comes with 1/8 NPT, 3/8 NPT and 1/2 NPT, hoping one of those works. I'm guessing that if it's detecting temperature there, the fluid level is that high in the transmission, and some is likely to run out when I pull that? I'm probably going to drop the pan and replace it with a deep finned pan anyway at the same time.
