Installing a transmission temperature guage in a 42RLE

I highly recommend the brazed bung option noted. đź’Ż % quality.

It may not be obvious, but we run the correct tap in after soldering to clean any solder or flux out of the threads. I actually had a guy tell me that the reason that his pan leaked according to his shop is that I brazed in a bung with the wrong threads in it. He was here when he was explaining that to me. I showed him the process and the taps that we keep here along with the fact that we do every single one that way without fail purely because there is no better way to get the flux out of the threads and they always get flux in them.

I also showed him the bin full of bungs that we use. I have yet to find one with the wrong threads.

As I’ve said before…. You sir, are a scholar and a saint. 🇺🇸

I don't think this has been covered and I apologize if I overlooked it. When installing the temp sensor for the gauge into the bung in the pan is any teflon tape or other product used on the threads? Or should it be installed bare?

The threads need something to seal them. I used Teflon tape on mine.

Thanks for the pic. Any chance you could post another pictures showing how you reputed it by the front drive line and exhaust/cats? I may be overthinking but I’m worried the sensor wire may get pretty hot by the exhaust/cats

I think I have a pic or two at home on my laptop. I’ll check went I’m home.

From my memory, I went along the side of the pan and transmission then up through the floor near the gear selector and to the gauge, which I mounted on the back of the center console.

Here's the best I could find.

I followed a factory harness on the drivers side of the transmission then over the top of it. I drilled a small hole in the floor near where the gauge is, put a grommet in there that was a tight fit on the wire that leads to the gauge.

I like mine there. I know I can’t fully see all the numbers from the seat. It gives me the info I need. I will say I would have liked to put it in front of the transfer case shifter put my console base that little pocket for storage and I didn’t want to lose that spot. If I had the kind of console that didn’t have anything there I would have gone that route. Ive never been really big on the A-pillar gauge pods, don’t want to just plop in on top of the dash somewhere. Thought about the flat spot under the HVAC controls but reserving that for some switches instead. I’m happy with my decision.

I greatly prefer the e-locker switches for the flat spot on the dash switch panel. That was priority for me.

Didn’t think I’d like digital gauges but I really like them since making the change. The center console location doesn’t obstruct the numbers at all so my brain knows the temp instantly with a brief glance. Autometer makes the same gauge for the transmission temp (comes in blue as well).

Liking the gauge so far in the A-Pillar as well.

I can see some of them.

I was good with my anolog gauge in that location bc my target number was vertical and I could see the numbers in the top right quadrant from the driver seat. I couldn’t see the colder temps, but I knew that before cutting the hole and didn’t care.

With that said, my current opinion is to go digital for that location because you can quickly compute the info (and get your eyes back on the road sooner).

I have mine in the same location and it's fine. Sure, I can't readily see the reading at the very lower end, but who cares? I can easily and quickly see the reading if it approaches the danger zone. That being said, I can understand if you go off road, things can heat up quickly and driving conditions don't warrant even a quick glance down. I don't go off road.
