What/How is/does the sending unit work on a Isspro. All I know is seeing the picture of the gauge only.

How does the sending unit install , any pix? What about this '94 trans line that has a fitting??? Is a electric wire run from a sending unit to the gauge or is it mechanical like a Stewart Warner water temp gauge?

The sensor just screws into the line and you attach a wire into the gauge.

 

2 wires run down to the senser. There is a driver/amplifier box to mount under the dash somewhere which drives the guage.
Simple install, not hard at all.

 

my isspro had a 3/4 sensor probe.....i just took the tranny pan off........drilled a hole on the bottom out of the way from hitting anything when the pan was put back on and used a 3/4 bolt and nut and screwed them together with the nut inside the pan and then i braised the pan and the nut together.......waalaaa.....tranny drain plug/ aka spot to screw in tranny sensor...... "man sometimes when i got nothing better to do i come up with the best ideas for installations....."
