Trans Temp gauge mounting

Installing the punisher valve body next week, along with the ATS kit, glow plugs and A pillar gauges. My question is, where is the best place to mount the tranny temp probe.
I've been told it's best to weld the bung onto the pan and also been told there's already a 1/8 NPT hole near where the lines come/go for the cooler. Do both locations provide accurate readings? Any experiences with it as far as which is best or is it personal preference or simplicity? It's the E4OD tranny and autometer gauges.

Ford trans tech explained the best place to put it once. I don't remember where but it wasn't in the pan.

On the driver side of the trans just above and in front of the neutral safety switch, there is an 1/8 npt plug you can remove and screw your sensor in. This will read the operating temp of the tranny

It's the pressure test port I think it's called. But yes, this is where most guys mount the temp sensor. I plan to mount mine there next weekend.

Is there one of these holes on the C6?

Yes, but i never tried putting a sensor in it, it might not be deep enough.

That sounds like the best option. Certainly better than hangin it off your pan. Seems like a great way to get it ripped off in the brush and loose all your tranny fluid and smoke it before ya know it.

Being a manual tranny guy till recently I remember the best place was a tee in the fluid out to the tranny cooler.

Bad part, I don't remember if fluid out was the front or back line.

Ran them both ways. You want the temp of the fluid your tranny is picking up. The temp in the line out to the cooler was hotter than what's in the sump of the pan.

The rear most line is the return line on the tranny.

If you do mount it in the pan, you want to mount it to the rear and on the vertical wall of the pan, NOT hangin down from the bottom. 2 reasons, road hazards and the wind under your truck will be enough to give false readings.

If I remember right, Fordtranstech (I hope that handle is right) said the fluid out gave a better indication of the tranny internal temps, which is what you want to monitor.

I read these threads every day, and usually just skim over the automatic threads because I have no experience.

My new truck has an E4OD, I should have been paying more attention.

I'll second the cooler line location. Thats basically going to be the hottest part of the fluid anywhere in the transmission (that you can actually reach with a sensor probe) and therefore, the most accurate. Anywhere from the outlet of the transmission up to the inlet to the cooler should give you a satisfactory reading. I need to do this on mine but never got around to it yet.

I've taken measurements from the pan with an infra red thermometer, and compared that to valve body readings (taken via laptop interphase to the controller) and the difference was already about 10F. I heard some one else confirming similar results. Over all, the pan is probably the worst possible place to mount your temperature sensor because its not a realistic source for how hot the transmission is really running.

I have tried the temp sender in both cooler lines. First in the line from the convertor to the cooler. I found the gauge would spike with load, which makes sence as the convertor is the heat source. However it was not a good indication of transmission temp, as it would do this even with the transmission cool enough to hold your hand on it. The instructions on the guage said to install in the return from the cooler. This results in steady reading that will rise with load, but not spike. It was a B & M guage.... Don

Like I said I ran it both ways and went back to manufacturers reccomendations of measuring the sump temp not the out going used atf. Like Don said with the fluctuations and at times almost pegging the autometer gauge your not getting the best readings. My opinion it's better to know what the tranny is taken in, an over all temp will suffice.

Throwin a boost question log on the fire

The gauge should be here tomorrow (here in PO-DUNK you can't just drive down the street and pick one up, it's all done online) and I'll see what Autometer recommends compared to all the good advice you all have. Much prefer gettin the actual "hands on" info. The more I think about it, the less I like the idea of pan mounting. You never know what kind of situation you're gonna get in "off the road" (or on the road if you live in jack rabbit country) and 16 quarts of hot tranny fluid would drain pretty fast out of a .343 hole in your pan. Boost. (I'm only kinda sorta off topic) When the ATS kit goes on I know I'm going to be asked about setting the waste gate. What's a "relatively" safe amount of boost to throw at it on a factory motor with out the head studs?

safe side 10-12. Of course EGT's also effect gasket failure (among melted piston tops) so keep it below 1100*f.
