trans temp sender in Pressure Port?

[tsmurphy72]

Looking to see who has done this and seen no problems and is it safe? I have been searching many post. People are using the pressure port on the 4L60E for the temp sender. I was worried about the depth of the sender. Will it block a passage? Has anyone seen the inside of the trans? I checked the depth of the port and it is real close. The sender tightens in and there are no leaks. I am concerned that the added length of the sender could block a passage inside. Some gauge manufactures state to install in the pressure port. I have not had a 4L60E apart to know how the protrusion of the sender effects anything inside the trans. The other solution is to weld a bung into the pan. I looked into the instrument cluster route but to expensive. Nothing is ever easy. Thanks for the help

Hi,
The pressure port seems to be an ok place from what I've seen.
I looked at three gauges from NAPA but the temps were too compressed in the operating range to be clear while driving.
Then I visited a speed type shop and saw the B&M gauge.
B&M has been a tranny beef up company for years.
It was perfect. It comes with a mounting housing also.
The gauge number range is easy to read and has color code background.
The sender mounts in a tee that you cut into the fluid line.
It really put my mind at ease while towing my fifth wheel trailer.
