Can someone get me a pic or a diagram of where the transmission test port is on a Torque flight 727 three speed. I'm doing a temp gauge and iv got no clue where the port is.

 

Test ports aren't a good place to install a temp gauge. Test ports are on the right side of the trans. Three of them first one is the front servo test port (closest to bellhousing), 2nd port is line pressure port, 3rd is the rear servo test port.

 

Okat where is a good spot to put the temp gauge?

 

Either in the pan or the hot line coming out. The pan gives you a good average. The hot line tells you the hottest point.

Where is the "hot line"

 

It's the line that comes out the tranny and heads to the cooler.

 

the front one just behind the bellhousing
