Tranny Question

i use a test port on teh side of my trany in my 92 dodge. i also take into account that it is an average temp just like the pan. i was in a hurry and wanted the gauge in for teh first trip. been meaning to tap into the hot line out. jiMMy

So if I tap into a line which do I want to hit? The hot out or the line in after the cooler? I was told by a local shop the line in but that doesn't sound right

It really comes down to personal preference. If you want the absolute maximum temp to be displayed, go with the hot line out of the tranny. If you want to see the temp of the fluid going into the tranny from the cooler, then tap into the cool line in. If you want an average temp of what's in the pan and about to be sucked into the pump, install a bung in the pan and put your sender in there.

I prefer to know what the fluid in the pan runs at, so I put my sender in the pan. I bought a bung from autometer and welded it in.

The important thing is to know where you are getting your reading and understand what the appropriate temp is for that spot. You don't want atf to go over about 250*F, so consider that your max temp if you tap into the hot line. Your pan and cool line should be significantly lower than what the hot line would read- mine runs about 160*f and may get to 180*F under extreme situations.

thanks for the info....That will help, so if I use the pressure port it should run about the same temp as the pan?
