47RE fluid temp?

Yea that’s rough man. 

 

Either way, sounds like you’re currently tapped into one of the hot lines or areas that get little flow so show hot. This also comes into debate onto where to actually monitor temps. Most people on the forum say to monitor to hot return line. Everyone who actually works on these trans says to monitor the pan temp.

Which is true. 

 

But if you ask @Dynamic he'll say monitor the pan temperature. 

 

Like even in my case on the 1996 Dodge Ram 1500. I didn't have the bung at the time of the rebuild or I would of had Jon put it in for me. So when I got the gauge I used ISSPro's clamp on sensor setup for the hot line for now. I want to take the time and have the bung put in the rear of the transmission pan where Jon marked it for me. It will read the very same temperature that the PCM reports. Remember the stock transmission temperature sensor is part of the governor pressure sensor which is once again inside the pan.

That’s what I was getting at when I said ‘everyone who works on these says...’

 

I’m not saying booking it up to the hot line is wrong. Just depends on what temp you wanna read. I personally see no point in knowing how hot the fluid is that’s going to be cooled. I want to know how hot it is before it’s being used. 

 

Just wanted to point out two different points of view from two different types of people.

I have my probe in the tranny case where the quadzilla says to put in in their manual. I plan on splicing it into the return line this summer, but right now with this cold it doesn't even register a temp. as the minimum is 100 F unless I got WOT for a stretch then it will come up to 105 but then back down to under 100F.

There is no port in the transmission where the fluid flows enough to be in any of those ports. Either put in in the pan or the return line. Personally, I'm going for the pan. I'm going to put the sensor down low in the pan so it doubles for a drain plug.

I have a deep dish MagHytec pan, when I rebuild the tranny after the truck is finished I'll move the sensor into the port in the pan.  I need to have a new larger cooler installed behind my bumper as my heat exchanger was leaking coolant when I removed it   I won't be running the truck anymore in the winter so am not concerned with the fluid not warming up enough

I actually bought the whole new tranny line with a port built in.. IIRC Genos had them.

So I have my sensor on the hot tranny line going to the cooler

 

My tranny runs cool. as  they all should unless your out of lock up pulling a steep grade

I had my tranny rebuilt last fall in late Sept., my heat exchanger (on the side of the block) wasn't leaking, but it was really crusty, so I had the tranny shop eliminate it (cost prohibitive through the dealer to replace) and I went with a large cooler from O'Reilly's that was bolted to my bumper ... I went with a deep sump pan from LPW Racing Products-phone # 717-394-7432, I used a GlowShift temp gauge and the sensor is in the pan, I drove the truck up until Dec. when the ECM went out, I only towed a light load with it in that time frame, and the temp never went above 150, other then that, the temp would only climb above the base temp of 100 when I was idling, or in city traffic ... I'm now waiting on my ECM to come back from Auto Computer Specialist, and I'm going to re-route my grounds/B+ while I wait ..... When I was searching for a deep sump pan I found that LPW had pans that were built like the Maghytec's, but priced like the Derale's, and you could buy it with/without the pan being pre-drilled for a temp sensor (at the time a $10. option for pre-drilled) ...

do you have any info on the added cooler you used on the front of the truck?

The correct spot to measure fluid temp. is in the pan. The same place your factory sensor is on ALL 47res. I use the rule of 100* above ambient before getting nervous about trans temp. The fluid is good until a bit over 200*s F (exact number is escaping me). The difference between the derale pan and any of the cast aluminum pans is........the derale will not support the case from twisting forces like the cast aluminum pan will.

I installed a B&M aluminum pan when I got my truck.  I don't think it holds any extra fluid, but it has cooling fins, a drain plug and a temperature port and was a heck of a lot cheaper than any other pans I looked at.  I was wondering where the factory temp sensor was today.  I had to do a lot of towing and noticed the Edge monitor was showing about 30* higher than my GS gauge which is in the pan.

How come you got the two different bolts in the side? 

 

The pan was meant to work on several different variations of this transmission.  I guess one version had a bracket that mounted there so they gave you 2 different bolts for that, but didn't give you 2 extra of the other ones if you didn't need the bracket.

@jlbayes, that's the same company that I posted the info for above, the only issue I had with the whole transaction was that his website said that you may have to sign for the package, and it's not a "may" it's a "definite", and at least at the time of my purchase it could only be sent to the billing address, I was working at the time of delivery, long story, short, I was able through Fed-X to change that arrangement, and had it sent to the tranny shop doing the work, and they signed for it..... Other then that hic-up it's a great deal for an extra capacity finned pan .....
