Trans temp gauge mounting?

Trans temp gauge mounting? I just got my Autometer tranny temp gauge and wanted to know if I could mount the supplied bung in the tranny pan? There are two different sizes and it looks like I could just drill into the pan and braze the bung in place. Then the sending unit will screw right in. I have heard of people buying drain plug kits and using that, but I want to make sure I can do it this way before buying more parts.
Also, what temps should I see in the pan? I originally wanted to mount the sending unit in the cooler line to monitor my highest temps, but I realize that it will be easier to mount it in the pan. All I need to know is what temps I should see there. It may not be the hottest temp the fluid reaches, but so I long as I know what is normal in that location I can rest assured that I am not burning up anything. Thanks for the info!

I Have mine mounted in the test port in the side of the transmission. The install is simple but this may not be what you are looking to do. With mine mounted in the test port the car has usually reads between 150-180 even with hard driving and in the summer heat. It is probably runs a little hoter than if you mounted it in the pan.

I have read that the test port won't give an accurate reading..but once again as long as one knows what the temp is supposed to be at any given point, it should'nt matter. For instance, the test port may run 150. The pan may run 175 and the cooler line might run 190. These are just guesses, but that's why I am trying to figure out the temp range for the tranny pan. Anybody know this as well as whether I can use the supplied bung?
I just installed my temp guage yesterday and used the test port and it seemed to work fine. It will give me atleast an idea of what the trans temp is and it was the easiest spot to put it. Im sure all the temps are pretty close anyway. The only thing I would really want to know is if the test port temp is hotter or colder then the fluid but im sure its pretty close so atleast I have a basic idea of what the temps are. Its alot better then having no gauge and not knowing what the temps are. If I notice my temps are to high ill prob bypass the radiator. I was driving for like 15 mins in the city in 80 degree weather and the temp was about 160 so thats not to bad. Ill have to do some more driving to get more of an avg temp though so hopefully it works out.I would be happy if the temp stayed around 180. Good luck.

Did you use a drain pan kit or the existing bungs that were supplied ???
I have a cast aluminum deep pan so the proper size hole was drilled and tapped and then the sending unit screws right in. You could only do this with a cast pan, I am assuming you have a stamped steel pan, If I remember correctly you should be able to use a drain plug kit and screw the sensor into it but I am not sure about that.
As for temps, my TH400 with a 4k stall stays right at 165 to 170 in 90 degree heat. Thats with a B&M hi tek cooler and I bypassed the radiator.

Thanks for the info...I guess I'm going to try using the supplied bung and have a shop braze it in place once I drill the hole. Then the sending unit will screw into that and I can run the wire up to the gauge. It's been really hot here...106-108 with the heat index so I am curious to see what temps I run. I was just looking for a comparison from others who measure from the pan. I have a B&M 24K and I too bypassed the radiator. If I am running too hot, I'll piggyback another 24K cooler and run two. Thanks again for the info. Anyone else want to post up temps they are running when measuring from the pan?
The very best way is to take your pan off and drill and tap a hole (3/8 npt I think) in the pan about half way down (vertically) on the side of the pan.
Any other way will give you bogus readings. I tried to tee off the tranner cooler line as some suggest but that did not work.

Besides that though, I don't think the discrepancy is going to be that much. If your trans is getting hot enough to start causing problems, you'll know it no matter where the sensor is mounted.

Do you have pics? What size T fitting did you need and is the exit line from the tranny on the top or bottom?

I would like some more info on this t-fitting as well.
