Teflon

Would it be safe to use teflon tape when you screw in a sender for a transmission temp gauge? I'm using the test port on a 4R100 transmission 2001 7.3L PSD.

It would depend on if the sender unit has two wires or just one. If just one wire, there would be no ground return.

I have a 1-wire sender and used tape, but I made sure only a few threads closest to where you connect the wire were covered - further inside the port (once installed) were some bare threads to make the ground connection. try folding the tape in half if you do go that route.
