trans temp gauge
You tap a spot on the trans oil pan for the fitting.
I have been told that anywhere around your coolant temp is fine....but my buddies TH400 turbo car with a 3600 stall and a giant cooler never gets much above 140.

about 150* on the freeway and 180-210* city (210 on a hotter day, or driving hard)
I have my sender in a custom t-junction into the exiting coolant lines of the trans. Very accurate. Much more accurate than the pressure port on the driver's side of the trans.

This will give you an idea. I posted this up a few months ago. It works great and my temps are spot on with GoFast908Z's.

T-fittings like that can be bough at any hardware store. (Lowes, Home Depot, or even at Pep Boys or AutoZone, etc.)
I dont' knwo the size, but if you have your temp sender with you, you could always test fit standing in the store like I always do...

but you dont want to know how cool the cooled fluid is, but how hot the fluid inside the trans is. In a time of parts breakdown the internals of the trans will heat up much faster than the fluid coming out the cooler. it's better to know when the internals are overheating so that you can cut the car off before you cause more damage.

Exactly...how cool the temp gets means nothing to me. I simply want to know the hottest temps my tranny ever sees and this is the way to tell that. I don't remember the dimensions on the T-fitting. For ***** and giggles, I did this same thing for my water temp gauge since the sending unit is exactly the same as the one for the trans temp gauge. I used the T-fitting to do the TB bypass killing two birds with one stone. Pretty amazing how much difference there is in the displayed water temp on the factory gauge and the aftermarket one. Factory reads 210* all the time, aftermarket fluctuates between 180*-210*. I was supposed to get pics of that as well but haven't had a chance yet.
