Can I install this temp sensor in Ford E40D test port?

Hi all, I would like to know if it would be safe to install this 1/8" NPT temperature sensor probe in the test port of my 1990 E40D transmission with it's longer "nose", or if I need to get a port ...

I used the E40D test port on a previous 1995 F53 and found the temp readings to be quite reliable for monitoring the internal conditions. When I had a remanned E40D installed prior to installing the gauge, I noticed that the tech used that port for temp testing as well as pressure testing. He recommended using it for an aftermarket gauge as well. As to the temp sensor the OP is considering, I can only suggest that he probe the port to see if there's enough depth for it.
